Description

Data processing method and device and application server

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data processing method and apparatus, and an application server.

Background

In the communication operation process, due to the needs of a client, misoperation of an operator and the like, the situation that a completed service order often needs service rollback occurs, for example, the client orders a short message call service, the corresponding service order is processed and completed, the operator prompts that the client can use the short message call service, the client finds that the short message call service is not actually opened, and the operator helps the client to order the color ring package monthly combo due to operation error, so the operator needs to inquire the transacted service order, perform corresponding service rollback and reorder the correct short message call service for the client.

At present, in order to complete the rollback of a business order, a log table of corresponding entity state changes is usually designed, and the entity may be an order, an order product, or the like, that is, a Customer Relationship Management (CRM) system records which order causes the entity state to change, and what the value of the entity state before and after the change is, respectively, so as to "restore" the entity state stored in the CRM system to the state before the corresponding business order is completed and fulfilled, so as to complete the rollback of the business order.

However, for the entity state change, a corresponding entity state change log table needs to be maintained, and the entity state change log is subjected to corresponding logic processing, so that extra burden is added to developers, and problems such as service rollback and the like which do not meet conditions also occur.

The application server 102 comprises a memory 1021, a processor 1022, a system bus 1023, a power component 1024, an input/output interface 1025, a communication component 1026 and the like; the memory 1021 may be used for storing data, software programs, and modules, and mainly includes a storage program area and a storage data area, where the storage program area may store an operating system, an application program required by at least one function, and the like, and the storage data area may store data created by use of the application server 102, and the like; the processor 1022 executes various functions of the application server 102 and processes data by running or executing software programs and/or modules stored in the memory 1021 and calling data stored in the memory 1021, for example, the processor 1022 processes events in sequence according to an event sequence arranged on an event bus when processing the events, wherein the event bus is used for placing the events to be processed in the application server 102; system bus 1023 includes an address bus, a data bus, and a control bus for transmitting data and instructions; the power component 1024 is used to provide power to the various components of the application server 102; input/output interface 1025 provides an interface between processor 1022 and peripheral interface modules; the communications component 1026 is operable to facilitate wired or wireless communication between the application server 102 and other devices.

The storage server 103 and the application server 102 may be connected through a network or a data line, and the storage server 103 is mainly used for storing a domain event generated when the application server 102 executes or runs, where the domain event may be stored permanently or may be stored for a specified time. In addition, the storage server 103 may be a separate server for storage, or may be a part of the memory 1021 of the application server 102, that is, a domain event generated when the application server 102 executes or runs is stored in the memory 1021.

Fig. 2 is a data processing method provided in an embodiment of the present invention, which is applied to an application server that at least includes a first event bus and a second event bus, where the first event bus is used to transmit a domain event of a first operation on a service, and the second event bus is used to transmit a domain event of a second operation on the service, and referring to fig. 2, the method includes the following steps.

Step 201: and receiving a data processing request, wherein the data processing request comprises a user identifier, an electronic certificate identifier and an operation type, and the electronic certificate is used for indicating that a preset state is met between a user and a service.

For example, when the electronic voucher is an order generated by a user ordering a service, the electronic voucher identifier may be an order identifier of the order, and the order identifier may be an order number used for indicating that the user orders the service.

In addition, the operation type comprises a first operation and a second operation, when the data processing request comprises a user identifier and an electronic certificate identifier, the operation type is the first operation, and when the data processing request comprises the user identifier and a service identifier, the operation type is the second operation. For example, when a user needs to handle or cancel a certain service, the first operation type may refer to canceling the handled service, and the second operation type may refer to handling the required service.

Step 202: if the operation type is a first operation, a first domain event is marked as a rollback event based on the electronic certificate identifier and a first corresponding relation, the first domain event is a domain event corresponding to the electronic certificate identifier, and the first corresponding relation comprises the electronic certificate identifier and the domain event corresponding to the electronic certificate identifier.

The first corresponding relation refers to the corresponding relation between the electronic certificate identifier and the domain event, the domain event corresponding to the electronic certificate identifier can be determined through the electronic certificate identifier, and the first corresponding relation can be stored separately or in an event database.

For example, if the user desires to cancel a previously handled short message call service, and the electronic certificate identifier is an order identifier during handling of the short message call service, the application server obtains a first domain event corresponding to the order identifier during handling of the short message call service, that is, an ordered short message call service, from the first corresponding relationship based on the order identifier during handling of the short message call service, so as to mark the ordered short message call service of the first domain event as a fallback event.

It should be noted that the first corresponding relationship, that is, the electronic certificate identifier and the domain event corresponding to the electronic certificate identifier, is stored when the electronic certificate is generated and the domain event is generated based on the electronic certificate identifier, and the specific methods for generating the electronic certificate and generating the domain event based on the electronic certificate identifier may refer to a data processing method whose operation type is the second operation, which is not described herein again in the embodiments of the present invention.

Step 203: inquiring an event database based on the user identification, and acquiring other field events except the first field event in the field events corresponding to the user identification; the event database comprises a user identification, a domain event corresponding to the user identification and occurrence time corresponding to the domain event.

The event database may include, in addition to the user identifier, the domain event corresponding to the user identifier, and the occurrence time corresponding to the domain event, the electronic certificate identifier, the data of the event, or the event state, and the corresponding relationship between the user identifier and the domain event, and the like, and in addition, the occurrence time corresponding to the domain event may be accurate to seconds, milliseconds, or microseconds, and the like, which is not limited in the embodiment of the present invention.

In addition, the event database may be stored in the application server, or may be separately stored in the storage server, and the data information in the event database may be permanently stored, or may be stored within a preset time duration, when the data information is permanently stored, the first operation may be performed on any domain event in the event database based on the user identifier and the electronic certificate identifier, and when the data information is stored within the preset time duration, the first operation may be performed on any domain event within the preset time duration based on the user identifier and the electronic certificate information, which is not limited in the embodiment of the present invention.

For example, the user identifier is 1234567, the electronic voucher identifier is an order identifier and is ID1, the first domain event is event 1, the application server queries the event database shown in table 1 below based on the user identifier 1234567, and obtains other domain events except for the event 1 from the domain events corresponding to the user identifier 1234567 as event 2 and event 3.

TABLE 1

It should be noted that, in the embodiment of the present invention, only the event database shown in table 1 is taken as an example for description, and the correspondence relationship between the user identifier, the order identifier, the domain event, the occurrence time of the domain event, and the event state shown in table 1 is not limited to the embodiment of the present invention.

Optionally, when the data information in the event database is stored within a preset time length, the application server obtains a domain event corresponding to the user identifier within the preset time length before the current time from the event database; if the domain event corresponding to the user identifier in the preset duration before the current time comprises a first domain event, deleting the first domain event and then acquiring other domain events except the first domain event; and if the domain event corresponding to the user identifier in the preset time before the current time does not contain the first domain event, sending error information, wherein the error information is used for indicating that the first operation has errors.

That is, only the domain events within the preset duration before the current time are stored in the event database, the domain events exceeding the preset duration before the current time are deleted, and if the first domain event belongs to the domain events within the preset duration before the current time, the first domain event is stored in the event database, so that after the first domain event in the domain events corresponding to the user identifier is deleted, other domain events except the first domain event are acquired; if the first domain event does not belong to the domain event within the preset time length before the current time, the first domain event is not stored in the event database, so that the application server can send error information to the user terminal, wherein the error information is used for indicating that the first operation is wrong, namely, the application server sends information that the first domain event cannot be backed back to the user terminal.

It should be noted that the preset duration may be set in advance, and the preset durations corresponding to different field events may be the same or different, which is not limited in the embodiment of the present invention.

For example, in the communication operation process, when the subscription short message call service is specified to exceed three months, the unsubscribe cannot be performed, if the first field event is the subscription short message call service, the preset duration is three months, the event database contains the first field event subscription short message call service in three months, the user can apply for rollback, if the subscription short message call service exceeds three months, the first field event subscription short message call service is deleted, and if the user applies for rollback, the application server sends information that the unsubscribe to the user terminal.

Step 204: and re-processing other field events in sequence according to the sequence of the occurrence time of the field events to obtain the processed service state information corresponding to the user identification.

Because each domain event has an event listener, the corresponding domain event is processed by the event listener, so that when other domain events are reprocessed in sequence according to the sequence of the occurrence time of the domain events, the other domain events can be sent to the first event bus in sequence according to the sequence of the occurrence time of the domain events, the corresponding event listener acquires the other domain events from the first event bus in sequence and processes the other domain events in a synchronous interception mode to obtain the processed service state information corresponding to the user identification.

The processing in the synchronous interception mode means that the sending and receiving processing of the domain events are performed in the same thread, thread switching is not performed, and it is ensured that each domain event is processed and then the next domain event is processed.

It should be noted that, when the system is initialized, the application server has corresponding event listeners for different domain events, and the purpose of the event listeners is to invoke different domain services for the different domain events, capture a domain event to be processed when the system is running, and invoke a corresponding domain service of the corresponding domain event, so as to process the corresponding domain event.

Step 205: and updating the service state information corresponding to the user identifier in a state database according to the processed service state information corresponding to the user identifier, wherein the state database comprises the user identifier and the service state information corresponding to the user identifier.

Because the state database comprises the user identifier and the service state information corresponding to the user identifier, the service state information corresponding to the user identifier is changed after the first operation is performed, and in order to restore the service state information corresponding to the user identifier in the state database to the state when the first field event does not occur, the service state information corresponding to the user identifier in the state database can be updated according to the processed service state information corresponding to the user identifier, that is, the service state information corresponding to the user identifier in the state database can be replaced by the processed service state information corresponding to the user identifier.

It should be noted that the status database is used to store the service status information of the user, and the status database includes a user identifier and service status information corresponding to the user identifier, and the service status information may include a service identifier, an electronic certificate identifier, creation time of the information, and the like, which is not limited in this embodiment of the present invention.

Optionally, referring to fig. 3, after step 203, the method further includes:

step 206: and if the second domain event and the first domain event in the other domain events have the preset incidence relation, sending error information, wherein the error information is used for indicating that the first operation has errors.

The preset incidence relation means that the first domain event and the second domain event are mutually correlated, and when the second domain event exists, the first domain event also needs to exist. For example, in the communication operation process, it is specified that package B includes a short message call service, if the second domain event is subscription package B, the first domain event is subscription short message call service, and since subscription package B is associated with subscription short message call service, when the second domain event subscription package B exists, the first domain event subscription short message call service must also exist.

Specifically, in other domain events, if there is a preset association relationship between the second domain event and the first domain event, it is determined that the first domain event cannot be backed, and therefore, the application server may send error information to the user terminal, where the error information is used to indicate that the first operation is in error, that is, the application server sends information that the first domain event cannot be backed to the user terminal.

The data processing method provided by the embodiment of the invention comprises the steps of receiving a data processing request, wherein the data processing request comprises a user identifier, an electronic certificate identifier and an operation type, if the operation type is a first operation, marking a first field event as a backspacing event based on the electronic certificate identifier and a first corresponding relation, then inquiring an event database based on the user identifier to obtain other field events except the first field event in the field events corresponding to the user identifier, sequentially reprocessing the other field events according to the sequence of the occurrence time of the field events to obtain the processed service state information corresponding to the user identifier, updating the service state information corresponding to the user identifier in the state database according to the processed service state information corresponding to the user identifier, and updating the service state information corresponding to the user identifier in the state database based on the existing service logic, the domain events except the rollback event are replayed in the forward direction, so that a change log table of state information does not need to be developed additionally, the burden of developers is reduced, and meanwhile, the condition of service rollback is guaranteed.

Fig. 4 is a data processing method provided in an embodiment of the present invention, which is applied to an application server, where the application server at least includes a first event bus and a second event bus, where the first event bus is used to transmit a domain event of a first operation on a service, and the second event bus is used to transmit a domain event of a second operation on the service, and the method includes the following steps:

step 301: and receiving a data processing request, wherein the data processing request comprises a user identifier, a service identifier and an operation type.

The operation type comprises a first operation and a second operation, when the data processing request comprises a user identifier and an electronic certificate identifier, the operation type is the first operation, and when the data processing request comprises the user identifier and a service identifier, the operation type is the second operation. For example, when a user needs to handle or cancel a certain service, the first operation type may refer to canceling the handled service, and the second operation type may refer to handling the required service.

Step 302: and if the operation type is the second operation, generating an electronic certificate based on the data processing request, wherein the electronic certificate is used for indicating that the preset state is met between the user and the service.

The step of generating the electronic certificate based on the data processing request means that the electronic certificate is generated based on the user identifier and the service identifier included in the data processing request. For example, in the communication operation process, the data processing request may be a request for a user to order a service, the application server may generate an order based on a user identifier and a service identifier that the user desires to order, where the order is used to indicate that the user orders the service, and the electronic certificate is a generated order at this time, and the electronic certificate identifier may be an order identifier of the order, and the order identifier may be an order number.

Step 303: based on the identification of the electronic voucher, a first domain event corresponding to the identification of the electronic voucher is generated.

The application server may further store the electronic certificate identifier and a first domain event corresponding to the electronic certificate identifier in a first corresponding relationship, where the first corresponding relationship may be separately stored or may be stored in event data.

For example, in the communication operation process, the user desires to order the short message call service, and the electronic certificate is an order, the application server may generate a first domain event corresponding to the order identifier based on the order identifier, that is, order the short message call service, and then may store the order identifier and the first domain event corresponding to the order identifier in the first corresponding relationship.

Step 304: updating an event database according to the first domain event, wherein the event database comprises a user identifier, a domain event corresponding to the user identifier and occurrence time corresponding to the domain event;

In addition, the event database may be stored in the application server, or may be separately stored in the storage server, and the data information in the event database may be permanently stored, or may be stored within a preset time length, when the data information is stored within the preset time length, only the domain event within the preset time length before the current time is stored in the event database, and the domain event exceeding the preset time length before the current time is deleted.

Step 305: processing the first domain event to obtain a service state corresponding to the first domain event;

specifically, before processing the first domain event, the first domain event may be sent to the second event bus, and since each domain event has one event listener, the corresponding event listener acquires the first domain event from the second event bus, and processes the first domain event to obtain the service state corresponding to the first domain event.

Step 306: and updating the service state information corresponding to the user identifier in a state database according to the service state corresponding to the first field event, wherein the state database comprises the user identifier and the service state information corresponding to the user identifier.

After the service state corresponding to the first domain event is obtained, the service state information corresponding to the user identifier in the state database may be updated according to the service state corresponding to the first domain event, that is, the service state corresponding to the first domain event in the state database may be added to the service state information corresponding to the user identifier.

Optionally, referring to fig. 5, after step 305, the method further includes:

step 307: according to a preset second corresponding relation, if the preset state is determined to comprise a first preset state and a second preset state which are mutually associated, and the second preset state is a necessary condition of the first preset state, determining a second domain event corresponding to the second preset state according to the preset second corresponding relation; the second corresponding relation comprises electronic certificate identification, domain events corresponding to the electronic certificate identification, and preset states corresponding to the domain events respectively.

For example, when the service that the user desires to order is package B, the electronic certificate identifier may be an order identifier, and since package B includes a short message call service, the two domain events corresponding to the order identifier are included, that is, the first domain event orders package B for the user, and the second domain event orders short message call service for the user.

In addition, the preset states respectively corresponding to each domain event included in the second corresponding relationship means that the second corresponding relationship includes state information corresponding to each domain event, for example, the preset state of the first domain event is a first preset state, and the first preset state is state information of the first domain event.

Specifically, the first domain event corresponds to a first preset state, the second domain event corresponds to a second preset state, and the first preset state and the second preset state are associated with each other, the application server determines whether the second corresponding relationship includes a second preset state associated with the first preset state based on the electronic certificate identifier and a preset second corresponding relationship, and if the second preset state is determined to exist, determines the second domain event corresponding to the second preset state according to the preset second corresponding relationship.

Step 308: and if the event database is determined not to have a second domain event corresponding to the second preset state, processing the first domain event and triggering to generate the second domain event.

When the second domain event is determined, whether the second domain event corresponding to the second preset state exists in the event database needs to be inquired, and if the second domain event corresponding to the second preset state does not exist in the event database, the second domain event needs to be generated by triggering after the first domain event is processed because the first preset state and the second preset state are correlated and the second preset state is a necessary condition of the first preset state.

For example, in the communication operation process, the package B includes a short message call service, the first domain event is that the user subscribes to the package B, the second domain event is that the user subscribes to the short message call service, and if it is determined that the second domain event does not exist in the event database, that is, the user unsubscribes to the short message call service, the package B needs to be subscribed to the user, and the second domain event for subscribing to the short message call service is triggered and generated.

Step 309: and if the event database is determined to have a second domain event corresponding to the second preset state, processing the first domain event.

When whether a second domain event corresponding to a second preset state exists in the event database is queried, if the event database is determined to have the second domain event corresponding to the second preset state, namely the second domain event already exists, the second domain event is not required to be generated in a triggering mode, and the first domain event is directly processed.

Optionally, referring to fig. 6, after step 308, the method further includes:

step 310: and updating the event database according to the second field event, and processing the second field event to obtain a service state corresponding to the second field event.

Specifically, before the second domain event is processed, the first domain event may be sent to the second event bus, and before the second domain event is acquired by the corresponding event listener, the second domain event is updated to the event database, and then, the corresponding event listener acquires the second domain event from the second event bus, and processes the second domain event to obtain the service state corresponding to the second domain event.

Step 311: and updating the service state information corresponding to the user identifier in the state database according to the service state corresponding to the second field event.

After the service state corresponding to the second domain event is obtained, the service state information corresponding to the user identifier in the state database may be updated according to the service state corresponding to the second domain event, that is, the service state corresponding to the second domain event in the state database may be added to the service state information corresponding to the user identifier.
