All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.

The embodiment of the invention provides a mail migration method, a mail migration device, electronic equipment and a computer readable storage medium. Specifically, the embodiment of the invention provides a mail migration method suitable for a mail migration device, and the mail migration device can be integrated in electronic equipment.

The electronic device may be a terminal or the like, including but not limited to a mobile terminal and a fixed terminal, for example, a mobile terminal including but not limited to a smart phone, a smart watch, a tablet computer, a notebook computer, a smart car, etc., wherein the fixed terminal includes but not limited to a desktop computer, a smart television, etc.

The electronic device may be a server, which may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network ), and basic cloud computing services such as big data and artificial intelligence platform, but is not limited thereto.

The mail migration method of the embodiment of the invention can be realized by a server or a terminal and the server together.

The mail migration method is implemented by the terminal and the server together, and the method will be described below.

As shown in fig. 1, the mail migration system provided by the embodiment of the present invention may include a user side device 10, a service side device 20, and the like; the user-side device 10 and the service-side device 20 are connected to each other through a network, for example, a wired or wireless network connection.

The user side device 10 may include a plurality of terminals, and provide functions of mail display, mail sending and receiving for the user, so that the user can perform mail management operations such as sending and receiving, deleting, and the like of the mail.

The service-side device 20 may include several servers, and provides various business services for the user. For example, a storage server that stores mail contents, pictures corresponding to the mail contents, storage addresses of the pictures, authentication tokens, and the like may be used, for example, a mail server that transmits, manages, and the like mail.

In some examples, the user side device 10 may be a terminal for performing mail migration operations for a user, for sending a mail migration request to the service side device 20.

The service side device 20 may be configured to obtain a mail migration request through an access layer of the mail migration system, and generate a mail migration task based on the mail migration request; through a logic layer of the mail migration system, selecting a target queue for writing mail migration tasks from task execution queues controlled by the logic layer, and writing the mail migration tasks into the target queue, wherein the tasks in one task execution queue are executed by one server; determining a target server corresponding to a target queue in the distributed deployed servers, and reading a mail migration task which needs to be processed currently from the target queue through the target server; acquiring target mail data to be migrated based on a mail migration task through a target server; and E, based on the target server, performing mail migration on the target mail data.

It will be appreciated that in some embodiments, the steps of mail migration performed by the service-side device 20 may also be performed by the user-side device 10, which is not limited by the embodiment of the present invention.

The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.

The embodiments of the present invention will be described in terms of a mail migration apparatus, which may be integrated in a server and/or a terminal in particular.

As shown in fig. 2, the specific flow of the mail migration method in this embodiment may be as follows:

201. and acquiring a mail migration request through an access layer of the mail migration system, and generating a mail migration task based on the mail migration request.

The mail migration system may be an organic whole having a migration function for user mails. In some examples, the mail migration system may include at least an access layer and a logic layer that are in communication with each other and interact to collectively implement mail migration functionality.

It can be understood that the mail migration system in the embodiment of the invention can provide mail migration service for external enterprises for enterprise-level mailbox users and can also provide mail migration service for common individual users.

For example, the mail migration system may migrate mails of one or more employee accounts corresponding to a certain enterprise, or may migrate mails of a certain personal account belonging to a person. When the mail migration system performs mail migration, all mails in a certain account or some accounts can be migrated, or only part of the mails can be migrated, which is not limited by the embodiment of the invention.

The access layer is a module in the mail migration system, which has functions of supporting cluster deployment, remote procedure call (Remote Procedure Call, RPC) and the like. The access layer provides a functional interface which can be called by other modules, so that communication with the other modules can be realized.

In some embodiments, the access layer may include one or more servers to obtain mail migration requests, respond to mail migration requests, schedule mail migration tasks, and so forth.

Specifically, the mail migration request may be generated based on an operation of the user at the user-side device. For example, the user side device may generate a mail migration request in response to a triggering operation of the user on the mail migration control, and send the mail migration request to the mail migration system.

Alternatively, the mail migration request may be generated by the service-side device. For example, due to the limitation of the storage space, mail data of employees in the same enterprise may be stored in different storage areas, and in order to facilitate management of the mail data, the service side device may generate a mail migration request to migrate the mail data stored in the different storage areas into the same storage area.

In some examples, the mail migration request may be just an instruction that can trigger the mail migration system to perform mail migration, and no other information is included. The mail migration system may send an information acquisition request to the user side device or the service side device that generates the mail migration request in response to the mail migration request, so as to acquire information that may be used in the mail migration process.

In other examples, in order to improve mail migration efficiency, the mail migration request may include migration indication information, where the migration indication information may be used to indicate migration associated information corresponding to the target mail data, and the step of "generating, by an access layer of the mail migration system, a mail migration task based on the mail migration request" may specifically include:

Acquiring migration associated information indicated by migration indication information from an information storage layer of the mail migration system based on a mail migration request through an access layer of the mail migration system;

The information storage layer of the mail migration system can be a data storage module which supports cluster deployment and is high in availability in the mail migration system and can be used for storing information such as mailbox information of users, mail migration states of all users, migration logs and the like.

Specifically, the migration instruction information can indicate information that is required to be used when migrating the target mail data. For example, the migration indication information may be a user identification (such as a user ID, a mailbox account number and a mailbox account number of the user, etc.) of the user initiating the mail migration; alternatively, the migration indicating information may be a storage location of migration related information in the information storage layer, and so on.

Wherein the migration related information is all or part of information required in the process of acquiring the target mail data and/or migrating the target mail data. Specifically, the migration association information may include, but is not limited to, a mailbox account number and a mailbox account number password of the user, an IP port of a server storing the target mail data, a migration protocol type adopted in the process of migrating the target mail data, and the like.

In the embodiment of the invention, the mail migration task is an instruction set which can be issued to a logic layer of the mail migration system for execution. The mail migration task may include migration related information, or may include a specific mail migration instruction, a mail migration parameter, and the like.

It can be understood that in the embodiment of the present invention, mail migration may be implemented in a cluster deployment manner, and in a mail migration system, there may be a case where several servers are running simultaneously. If a plurality of servers request migration related information from the information storage layer at the same time, information transmission errors may occur between the servers and the information storage layer, so that the information storage layer can give permission to acquire information to the servers of the access layer. That is, the step of "obtaining, by the access layer of the mail migration system, migration association information indicated by the migration indication information from the information storage layer of the mail migration system based on the mail migration request" may specifically include:

sending a permission acquisition request to an information storage layer of the mail migration system through an access layer of the mail migration system based on the mail migration request, and triggering the information storage layer to generate a permission issuing instruction based on the permission acquisition request;

And acquiring a permission issuing instruction, and acquiring migration associated information indicated by the migration indicating information from the information storage layer according to the permission issuing instruction.

The permission acquisition request is a request sent by the access layer to the information storage layer, so that the information storage layer is requested to allow a certain server to acquire migration related information. The authority issuing instruction is a code for allowing a certain server to acquire migration related information from the information storage layer.

Specifically, when the access layer sends the permission acquisition requests, the servers deployed in the cluster in the access layer can actually send the respective permission acquisition requests to the information storage layer synchronously. And the information storage layer can generate a right issuing instruction corresponding to any server according to the right acquiring request of each server.

In this embodiment, the rights acquisition request of each server may include identification information of each server, and the information storage layer may generate the rights issuing instruction for a certain server according to the identification information of the server in the rights acquisition request.

Alternatively, in other embodiments, the access layer may send the rights acquisition request of the access layer to the information storage layer when sending the rights acquisition request, and the information storage layer may generate the rights issuing instruction for the access layer. After the access layer acquires the authority issuing instruction, a server can be determined from the servers to acquire migration instruction information from the information storage layer according to the authority issuing instruction.

Alternatively, in other embodiments, the access layer may schedule servers deployed in the cluster, and when sending the rights acquisition request, may send the rights acquisition request of a certain server to the information storage layer. The information storage layer may generate a rights issuing instruction corresponding to the server according to the rights acquisition request of the server.

Optionally, in order to ensure the security of the information in the information storage layer and avoid the malicious program from acquiring the migration related information, the authority issuing instruction generated by the information storage layer may include verification information for acquiring the migration related information from the information storage layer.

202. And selecting a target queue for writing the mail migration task from task execution queues controlled by the logic layer through the logic layer of the mail migration system, and writing the mail migration task into the target queue.

In an embodiment of the present invention, the logical layer of the mail migration system may be a message queue module (MQ module) that supports cluster deployment and high availability.

The task execution queue may be a message queue controlled by a logic layer. The task execution queue may transfer mail migration tasks to be executed to a server corresponding to the task execution queue for execution.

The target queue is a queue written with the current mail migration task in one or more task execution queues.

In the practical application process, when the target mail data is migrated, the migration failure may be caused by the reasons of single machine failure, network connection failure and the like of the server. In order to avoid that the migration failure of some target mail data affects the overall service of the mail migration system, the migration result can be detected, and when the migration failure result exists, the task is timely redistributed. That is, the mail migration method provided by the embodiment of the present invention may further include:

detecting a migration result of the target server for mail migration of the target mail data;

when the migration result is migration failure, determining a mail migration task corresponding to target mail data of the migration failure;

the step of writing the mail migration task into the target queue is performed.

For example, as shown in fig. 3, the server MQ4 in the logical layer is down due to a fault, and all the mail migration tasks in operation are broken, so that the migration result of the target server for performing mail migration on the target mail data can be detected, for example, whether the sending of the mail migration tasks in operation is overtime is identified through the task scheduling of the access layer. If the migration result is that the migration fails, for example, the mail migration task is sent out overtime, the access layer can reinitiate the mail migration task, i.e. re-write the mail migration task into the target queue.

It can be understood that, for the situation that the server of the logic layer is down due to a fault, if the access layer finds that the server where the target queue written originally by the mail migration task is located cannot communicate when performing task scheduling, a new target queue can be determined, and the mail migration task is written into the new target queue. That is, the mail migration method provided by the embodiment of the present invention may further include:

when the mail migration task fails to be written into the target queue, selecting a task execution queue except the target queue from task execution queues controlled by the logic layer as a new target queue for writing the mail migration task;

the step of writing the mail migration task into the target queue is performed.

For example, after the access layer reinitiates the mail migration task with failed migration, it finds that the server MQ4 cannot be Ping-enabled, and then the mail migration task can be sent to other servers for processing, that is, a new target queue is determined, and the mail migration task is written into the new target queue, so as to ensure the stable overall migration.

The target server corresponding to the new target queue is different from the target server corresponding to the task execution queue whose migration failed.

It can be seen that in the embodiment of the invention, the modules such as the access layer, the logic layer and the like are split and deployed, and after each module is deployed with a cluster, even if a single machine fails, the response of cluster service is not affected.

In some alternative embodiments, because the amount of data to be migrated is large, if all mail data is migrated at one time, the required migration time will be relatively long, which affects the normal use of the user. Therefore, the same batch of data can be migrated at regular or irregular time and for multiple times according to the actual requirement of the user for mail migration. That is, the step of "obtaining a mail migration request through an access layer of a mail migration system, generating a mail migration task based on the mail migration request", includes:

the mail migration method comprises the steps of obtaining a mail migration request through an access layer of a mail migration system, and generating at least two mail migration tasks based on the mail migration request, wherein the mail migration tasks comprise task issuing time, and mail data which are corresponding to different mail migration tasks and need to be migrated are different.

The task issuing time may be a time or a time period. The access layer can determine the task issuing time of the generated mail migration task according to the number of mail migration tasks currently being executed or waiting to be executed, the importance degree of mail data corresponding to the generated mail migration task and other factors.

For example, the access layer may determine to generate three different mail migration tasks according to the mail migration request, so as to implement migration of mail data corresponding to the mail migration request. Mail data corresponding to the mail migration task 1 may be mails sent and received by a user within 7 days recently, mail data corresponding to the mail migration task 2 may be mails sent and received by the user within 7-30 days, and mail data corresponding to the mail migration task 3 may be mails sent and received by the user 30 days ago.

Correspondingly, before the step of "selecting, by the logic layer of the mail migration system, the target queue for writing the mail migration task from the task execution queue controlled by the logic layer", the mail migration method provided by the embodiment of the present invention may further include:

judging whether each mail migration task meets the task issuing conditions or not based on the task issuing time of each mail migration task;

and issuing the mail migration task meeting the task issuing condition to a logic layer of the mail migration system through the access layer.

The task issuance condition may be that a time interval between the current time and the task issuance time (a certain time) is not greater than a preset issuance time threshold, or may be that a time interval between the current time and a start time or a final time of the task issuance time (a certain time) is not greater than a preset issuance time threshold, or the task issuance condition may be that the current time is within the task issuance time and the mail migration system may execute the mail migration task, or the like.

By the aid of the method, the mail data can be migrated at regular or irregular time and multiple times, so that the number of users supported by the mail migration system is increased, and the service capacity of the mail migration system is improved.

203. And determining a target server corresponding to the target queue in the distributed deployed servers, and reading the mail migration task which needs to be processed currently from the target queue through the target server.

In the actual application process, the execution of the mail migration task in the target queue actually requires the server to provide hardware or software resources. For example, the mail migration task in the target queue may be specifically performed in the server by running a thread or process.

In the embodiment of the invention, the servers of the logic layer can adopt a distributed deployment mode, so that an expandable cluster structure is realized, and the execution pressure of mail migration tasks is reduced.

It is understood that there may be one or more target servers corresponding to the target queue. For example, if the logical layer determines that the task amount of the mail migration task in the target queue is smaller, only one target server may be allocated to process the mail migration task. If the logic layer determines that the task amount of the mail migration task in the target queue is large, a plurality of target servers can be allocated to process the mail migration task.

In general, if mail migration is too long, the user's experience of use is greatly affected. Therefore, when the processing capacity is insufficient, service expansion needs to be performed in time to avoid the too long time for mail migration.

For example, in some examples, the mail migration request may include a target migration duration, and before the step of "performing mail migration on target mail data based on the target server", the mail migration method provided by the embodiment of the present invention may further include:

predicting the actual migration time length of the mail migration process according to the target mail data and the target queue;

if the actual migration time length is longer than the target migration time length, determining a new target queue and a new server corresponding to the new target queue, so that the new actual migration time length predicted based on the new target queue is not longer than the target migration time length.

The target migration duration may be a time set by the user through the user side device, or may also be a time set by the service side device according to a requirement. For example, the service side device needs to migrate mail data of different storage areas to a designated area before a certain time, and at this time, the target migration duration may be set according to the time.

Specifically, the actual migration duration may be determined according to the data amount of the target mail data and the number of target queues scheduled by the logic layer. For example, when the number of target queues is the same, the larger the data amount of the target mail data, the longer the actual migration period is.

Correspondingly, in the mail migration process, the mail migration can be performed by a newly-added server through the target server. That is, the step of "performing mail migration on target mail data based on the target server" may specifically include:

and E, performing mail migration on the target mail data based on the target server and the newly added server.

For example, if the number of members of the enterprise a is huge and the migration task cannot be completed as expected according to the current processing capacity of the MQ of the logical layer, as shown in fig. 4, at this time, the transverse capacity expansion can be performed on the MQ of the logical layer alone, and the cluster migration capacity can be improved by increasing the number of MQ, i.e. increasing the number of servers, without modifying codes, which is very convenient.

In the embodiment of the invention, the modules such as the access layer, the logic layer and the like are split and deployed, so that the capacity can be independently expanded according to the bottleneck in the mail migration process, and the resources are saved. For example, when the single scheduling speed of the access layer is too slow, the access layer can be expanded, so that the scheduling capability of the access layer is enhanced.

204. And acquiring target mail data to be migrated based on the mail migration task through the target server.

In particular, the mail data may include, but is not limited to, the mail body, sender, attachment, signed content, etc. of the individual mail of the user. The target mail data is data corresponding to a currently executed mail migration task in the mail data.

Wherein mail data may be stored in a data source. The data source includes mail data that can be migrated. It will be appreciated that the data source and information storage layers may be two distinct modules, as shown in fig. 5. For example, the data source may actually be a database that provides data support for conventional usage procedures for mailboxes, such as mail deletion, mailing, etc., while the information storage layer may be a database that provides data support for mail migration procedures.

In some alternative embodiments, in order to facilitate rapid determination of the cause and location of the problem when the mail migration is problematic, migration record information generated during the mail migration may be included. That is, the mail migration method provided by the embodiment of the present invention may further include:

obtaining migration record information generated when mail migration is carried out on target mail data;

In the practical application process, the information storage layer can set effective time for the stored migration record information. When the existing migration record information is invalid, the invalid migration record information can be deleted to save storage resources. Alternatively, when the storage resources are sufficient, the invalid migration record information may not be deleted, which is not limited by the embodiment of the present invention.

205. And E, based on the target server, performing mail migration on the target mail data.

In the embodiment of the invention, the logic layer can manage a plurality of worker nodes for executing mail migration tasks, and the server resource is scheduled to provide resources for the worker to process the mail migration tasks. The worker may migrate data according to mail migration tasks.

In the actual mail migration process, different mail migration types exist, and migration programs required in migration are different. Thus, the mail migration task may include a target mail migration type of the mail migration process, and the step of "performing mail migration on target mail data based on the target server" may specifically include:

Analyzing the mail migration task based on the target server to obtain a target mail migration type corresponding to the mail migration task;

and migrating the target mail data based on the target migration program.

For example, the scheduling task in the logic layer message queue is processed by a Worker, and the Worker judges the migration type used by the user according to the target mail migration type corresponding to the mail migration task, determines the corresponding migration program as the target migration program, and starts to migrate data.

Specifically, the mail migration type may be a mail transmission type corresponding to a different mail transmission protocol. For example, mail migration types may include, but are not limited to, simple mail transfer protocol (SMTP protocol), post office protocol (POP protocol), internet information access protocol (IMAP protocol), and so forth.

The target mail migration type is a mail transmission type adopted when target mail data are migrated.

It can be understood that some functions in the mail migration process can be implemented by general codes, such as logging in, acquiring a folder list, downloading a designated id mail, etc., when determining a target migration program, the general codes can be directly called to implement the functions, and codes related to the mail migration type, which are not general, are determined according to the mail migration type, that is, the step of determining the target migration program corresponding to the target mail migration type specifically includes:

According to the target mail migration type, determining a target migration function corresponding to the target mail migration type from migration functions corresponding to at least one preset mail migration type;

The target migration function may be a function code which cannot be applied to data of each mail migration type, and corresponds to the target mail migration type.

It will be appreciated that the target migration function may include both generic code and non-generic code, in which case the target migration function may be referred to as a target migration program. Alternatively, the target migration function may include only code that is not generic, and the target migration function and the generic code may be combined when the target migration program is generated.

As shown in FIG. 6, general functions of mail Migration, such as logging in, obtaining a folder list, downloading a designated id mail, etc., are defined in the Migration module base class Migration, and the specific implementation is that the sub-class inheriting it implements the corresponding function according to the requirements of different protocols.

The class migrationfactor realizes the creation mode of all types of migration modules, and when in use, the corresponding migration modules can be created only by inputting the corresponding protocol types. When the expansion is required to adapt to a new protocol, the expansion can be completed only by realizing a new subclass and adding a corresponding creation mode into the subclass.

In the practical application process, besides mail migration, the user may have other functional requirements, for example, sending a prompt message before mail migration or after mail migration is completed. In order to reduce the code modification cost and the code invasiveness, the functions other than mail migration and the migration program for executing the mail migration functions are separated in the embodiment of the invention, so that the customization demands of different users are realized. Before the step of generating the target migration program corresponding to the target mail migration type based on the target migration function, the mail migration method provided by the embodiment of the invention may further include:

and acquiring an extended function code, wherein the extended function code is used for realizing an extended function in the mail migration process.

Specifically, the extension function may be to push a reminder message to a client of a user performing mail migration when the mail migration starts, or send a reminder mail to the user performing mail migration after the mail migration ends, and so on. The extended function codes corresponding to the different extended functions may be different codes according to the function design.

Correspondingly, the step of generating a target migration program corresponding to the target mail migration type based on the target migration function includes:

Generating a target migration program of the mail migration process according to the target migration function and the extended function code;

at this time, the step of "migrating the target mail data based on the target migration program" includes:

executing the extended function code in the target migration program;

The procedure for executing the extended function code in the target migration program and the procedure for migrating the target mail data based on the target migration function in the target migration program are not limited in order.

As shown in fig. 7, the extended function code may be executed (Before auth) Before the target migration function (Do imap.auth ()) is executed, or may be executed (After the target migration function is executed (After auth). The setting can be specifically performed according to the actual demands of the user.

For example, the enterprise CorpA requests to send an email notification when the user starts using the IMAP migration task, and then the function of the target migration function corresponding to the IMAP type is not changed, and only needs to insert new email notification logic after the Auth identity is verified.

For example, to avoid modification of the code of the target Migration function corresponding to the generic IMAP type, the system uses a decorator mode, as shown in fig. 6, where the CorpA inherits the base class Migration and is used as the target Migration function corresponding to the IMAP type, and in the CorpA detector class, the target Migration function corresponding to the IMAP type is initialized as a member variable in the class. In implementing the base class migration interface as in fig. 7, an implementation in IMAP is actually used, but code may be inserted before and/or after its execution.

In some alternative embodiments, the target migration program may also be preset, that is, the step of determining the target migration program corresponding to the target mail migration type includes:

and determining a target migration program corresponding to the target mail migration type from migration programs corresponding to at least one preset mail migration type according to the target mail migration type corresponding to the mail migration task.

According to the mail migration method provided by the embodiment of the invention, as shown in fig. 14, in the service evolution process, as the call volume is higher and higher, the logic layer service expansion supports the mail migration requirement.

As shown in FIG. 15, when the mq36 goes down on a certain day 17:24-17:35, the migration request cannot be processed normally, but the whole cluster service is not affected in FIG. 16, and the tasks of the mq36 are uniformly distributed to other machines, so that high availability is realized.

It can be seen from the above that, in the embodiment of the present invention, a mail migration request may be obtained through an access layer of a mail migration system, a mail migration task is generated based on the mail migration request, a target queue for writing the mail migration task is selected from task execution queues controlled by a logic layer through the logic layer of the mail migration system, the mail migration task is written into the target queue, wherein, a task in one task execution queue is executed by one server, a target server corresponding to the target queue in a distributed deployment server is determined, the mail migration task currently required to be processed is read from the target queue through the target server, target mail data required to be migrated is obtained based on the mail migration task through the target server, and mail migration is performed on the target mail data based on the target server; in the embodiment of the invention, the mail migration system comprising the access layer and the logic layer is designed, and the servers corresponding to the task execution queues in the logic layer are distributed, so that the splitting of mail migration service is realized, the coupling of mail migration flow is reduced, the queues for mail migration can be expanded at any time, the mail migration processing capacity is enhanced, and the mail migration efficiency is improved.

The method described in the previous examples is described in further detail below by way of example.

In this embodiment, a description will be given with reference to the system of fig. 1.

As shown in fig. 8, the specific flow of the mail migration method in this embodiment may be as follows:

801. the service side equipment acquires a mail migration request through an access layer of the mail migration system, and generates at least two mail migration tasks based on the mail migration request, wherein the mail migration tasks comprise task issuing time and target mail migration types of mail migration processes.

Mail data which are corresponding to different mail migration tasks and need to be migrated are different.

As shown in fig. 9, the access layer module a performs the scheduling task at regular time according to the configuration parameters, and because of the cluster deployment, there are multiple servers running at the same time, but only one server is expected to perform scheduling, so that the distributed lock needs to be acquired first, and here, the optimistic lock can be simply implemented by using the storage layer database.

By means of the distributed lock, it can be ensured that when a plurality of threads are concurrent, only one thread operates the service, the method and the variable at the same time.

The access layer server which acquires the distributed lock starts to run the scheduling program, acquires user information which needs to be migrated from the storage layer database, including account passwords, request server IP ports, migration types and the like, and generates mail migration tasks. And sending the migration task to the logic layer message queue.

802. The service side device judges whether each mail migration task meets the task issuing conditions or not based on the task issuing time of each mail migration task, and issues the mail migration task meeting the task issuing conditions to a logic layer of the mail migration system through the access layer.

In some alternative examples, the task issuing condition may be null, that is, after the server of the access layer generates the mail migration task, the mail migration task may be directly sent to the logic layer, and the logic layer determines the execution time of the specific mail migration task, and so on.

803. The service side equipment selects a target queue for writing the mail migration task from task execution queues controlled by a logic layer through the logic layer of the mail migration system, and writes the mail migration task into the target queue.

804. The service side equipment determines a target server corresponding to a target queue in the distributed deployed servers through a logic layer, and reads the mail migration task which needs to be processed currently from the target queue through the target server.

As shown in fig. 10, when a task is scheduled to be executed in the logical layer message queue, an executor, i.e., a worker, may be created. And the mail migration task is processed by a workbench. The corresponding key node log and failure log in the migration process can be written into the storage layer immediately. And storing the migrated folders and mails into a target mail system.

The mail system generally refers to a mail service providing system supporting mail storage and inquiry.

805. The service side equipment analyzes the mail migration task based on the target server to obtain a target mail migration type corresponding to the mail migration task.

The Worker can judge the target mail migration type used by the user according to the task information in the mail migration task, and creates a corresponding migration module through a protocol factory to start migrating data.

806. The service side equipment determines a target migration function corresponding to the target mail migration type from migration functions corresponding to at least one preset mail migration type based on the target server according to the target mail migration type.

The general function of mail Migration, such as logging in, obtaining a folder list, downloading a designated id mail, etc., is defined in the Migration module base class Migration, and the specific implementation is that the sub-class inherits the general function according to the requirements of different protocols.

The factory class migationfactor realizes the creation mode of all types of migration modules, and when the factory class migartion factor is used, the corresponding migration modules can be created only by inputting the corresponding protocol types. When the expansion is required to adapt to a new protocol, the expansion can be completed only by realizing a new subclass and adding a corresponding creation mode into the factory class.

The use of modular code design can reduce the need for customization, development costs for protocol extensions.

807. The service side equipment acquires the extended function code through the target server of the logic layer, and generates a target migration program of the mail migration process according to the target migration function and the extended function code.

The extended function code is used for realizing the extended function in the mail migration process.

The use of modular code designs can reduce development costs for customization needs. The adaptation of all protocols is uniformly managed through a factory mode, and the custom requirement of an inserting enterprise is realized by using a decorator mode, so that the modification cost and the code invasiveness can be greatly reduced.

808. The service side device executes the extended function code in the target migration program based on the target server of the logic layer, and migrates the target mail data based on the target migration function in the target migration program.

In the embodiment of the invention, the split service is used for independent deployment, so that the coupling between modules is reduced, and the capacity can be transversely expanded at any time when stronger processing capacity is required; the single service cluster is decentralised, and a small number of machine faults can not influence the normal running of migration.

In typical application scenarios such as enterprise-oriented mail migration service, the method and the system can be used for constructing a set of mail migration system with high flexibility, so that stable migration service is realized. The use of modular code design reduces the need for customization, development costs for protocol extensions. The service is decoupled by using the micro-service design concept, and the service is deployed according to the functional clusters, so that the service capacity is conveniently expanded, the processing capacity is improved, and the service availability problem of the single-machine service is solved.

In order to better implement the method, correspondingly, the embodiment of the invention also provides a mail migration device.
