Specific embodiment
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
Fig. 1 shows the flow diagram of the method for data synchronization for computer room of one embodiment of the invention.Such as Fig. 1 institutes
Show, this method includes：
Step S110：First computer room is performed to be operated with the corresponding multiple updates of update request received.
Wherein, the update request that the first computer room receives may be to be sent by terminal user, it is also possible to be used by O＆M
What family was sent.Also, updating the type of request can include a variety of, be specifically dependent upon class of business, the present invention is to detail
It does not limit.For example, update request may be to update request for increasing the comment class of a user comment, it is also possible to be used for
Realize that the class update that thumbs up for thumbing up function is asked.
Wherein, a update request would correspond to multiple update operations.Specifically, it is more corresponding to a update request
It is a update operation can both be directly contained in update request required parameter in, so as to parse the update request by way of come
Determine corresponding multiple update operations.It can also be pre-set simultaneously alternatively, the corresponding multiple updates of update request operate
It is stored in request executing rule, so as to determine that corresponding multiple updates are operated by inquiring about default request executing rule.
In above-mentioned two ways, user need to only trigger once update request, and backstage i.e. can the multiple correspondences of automatic trigger
Update operation, for example, exemplified by thumbing up class update request, user, which need to only trigger, once thumbs up class update request, from the background can be from
It is dynamic to perform following two updates operation according to default request executing rule：(1) modification is with thumbing up in the corresponding network of operation
The dispaly state of appearance；(2) sent to user relevant with the Web content and thumb up notification message.Correspondingly, in this step, press
This two update operations are performed successively according to the execution sequence of above-mentioned two update operations, to complete to thumb up class update request for this
Renewal process.
In addition, in other realization methods, a update request may need user to perform multiple trigger action, every time
Trigger action corresponds to a update son request, and each update request corresponds to one or more updates and operates.For example, with
Exemplified by commenting on class update request, user needs to perform following trigger action successively：(1) comment below Web content is clicked on to enter
Mouthful, so that the first computer room receives the first update son request included in comment class update request；(2) in comment input frame
Corresponding comment content is inputted, so that the first computer room receives the second update son request included in comment class update request；
(3) the submission entrance that comment is submitted in confirmation is clicked on, this to be submitted to comment on, and the first computer room is made to receive comment class update and is asked
The 3rd update son request included in asking.Every above-mentioned update son request corresponds at least one update and operates.For example, first
Update son request corresponds to the update operation of display comment input frame；Second update son request corresponds to display comment content more
New operation；3rd update son request correspond to modification Web content comment state update operate and to in the network
Hold the update operation that relevant user terminal sends a notification message.In this kind of mode, the multiple updates identical by purpose is performed
Son request is determined as a update request.
It can be seen that the present invention does not limit the specific intension and realization method of update request, a update is not limited yet
The concrete type and realization method of the corresponding each update operation of request.
Step S120：The corresponding multiple operation notes of multiple update operations are encapsulated as a piece of news according to execution sequence
Data.
Wherein, often there is stringent execution sequence between the corresponding multiple updates operation of a update request, in step
Each update operation must be performed in rapid S110 successively according to the execution sequence.Correspondingly, in this step, it is also desirable to according to this
Multiple operation notes are encapsulated as a piece of news data by execution sequence.
Specifically, it is multiple corresponding to update request when a update request only needs user to trigger once-through operation
Execution sequence between update operation can be both directly contained in the required parameter of update request, can also be pre-set and be deposited
Storage is in above-mentioned request executing rule；When a update request needs user to trigger multi-pass operation, update request institute is right
The triggered time that the multiple updates operation answered can combine multiple trigger action determines.It can be seen that the present invention do not limit it is each
The specific method of determination of execution sequence between update operation.In addition, each update operation corresponds to an operation note, it is used for
Record the relevant informations such as operation object, action type of update operation, in order to according to the operation note synchronization implementation this more
New operation.In short, the present invention needs to remember the corresponding each operation of each update operation for being under the jurisdiction of same update request
Record is encapsulated as a piece of news data.Also, each operation note is ensured in this message data to be carried out according to execution sequence
Encapsulation, to prevent the generation of disorder phenomenon.
Step S130：By message data storage into default message queue, so that the second computer room is according in message queue
It is synchronous that each message data of storage carries out data.
Wherein, message queue can be various forms of message queues, as long as the caching function of message data can be realized
.By each message data generated in above-mentioned steps storage into the message queue, the second computer room is as the message queue
Consumption terminal, be responsible for consuming each message data in the message queue, and real with the first computer room according to the message data of consumption
Existing data are synchronous.
By foregoing description, whenever the first computer room is there are during data update, then corresponding new information queue, the second machine
Data synchronizing function is realized by consuming the message data in message queue in room.Wherein, since message queue acts as the first machine
Intermediary between room and the second computer room, therefore, it is possible to realize the bi-directional synchronization function between multiple computer rooms.
It can be seen that in the present embodiment, by being added between the first computer room and the second computer room for buffered message
Message queue, it is achieved thereby that the bi-directional data simultaneously operating between multiple computer rooms.Further, since corresponding to a update request
Multiple updates operation between possess stringent ordinal relation, therefore, in order to prevent because of each message data in message queue
Between there is execution sequence that is out of order and influencing the corresponding multiple updates operation of same update request, same update is asked
Corresponding multiple operation notes are encapsulated as a piece of news data according to execution sequence, so as to prevent the occurrence of out of order,
Ensure the correctness of synchronizing process.
Fig. 2 shows the flow diagram of the method for data synchronization for computer room of another embodiment of the present invention.Such as Fig. 2
Shown, this method includes：
Step S210：The action type for the corresponding each update operation of update request that first computer room is determined and received
And execution sequence, each update is performed successively according to the action type and execution sequence of each update operation operates.
Wherein, the update request that the first computer room receives may be to be sent by terminal user, it is also possible to be used by O＆M
What family was sent.Also, updating the type of request can include a variety of, be specifically dependent upon class of business, the present invention is to detail
It does not limit.For example, update request may be to update request for increasing the comment class of a user comment, it is also possible to be used for
Realize that the class update that thumbs up for thumbing up function is asked.Wherein, a update request would correspond to multiple update operations.In this step
In, it is thus necessary to determine that the action type and execution sequence of the corresponding each update operation of a update request：
Specifically, in the first realization method, the action type of the corresponding multiple updates operation of a update request
It can be directly contained in execution sequence in the required parameter of update request, thus come really by way of parsing update request
Fixed corresponding multiple update operations.For example, when a update request corresponds to three update operations, in update request extremely
The required parameter of each update operation is corresponded respectively to comprising three less, also, correspondence can determine by each required parameter
Update operation action type and execution sequence.
Alternatively, in second of realization method, the action type of the corresponding multiple updates operation of a update request and
Execution sequence can also pre-set and be stored in request executing rule in, so as to by inquire about it is default request executing rule come
Determine corresponding multiple update operations.When it is implemented, first, the request type of update request received is determined, for example, can
The type of update request is determined with the request message head according to update request or required parameter.Then, according to default request
Executing rule determines the action type and execution sequence with the corresponding each update operation of the request type.For example, it deposits in advance
Storage and the corresponding request executing rule of various request types, by inquiring about the request executing rule of corresponding types, can determine
With the action type and execution sequence of the corresponding each update operation of the request type.For example, it can pre-set and thumb up
The corresponding update operation of class update request including " changing and thumb up the dispaly state for operating corresponding Web content " and
" sent to user relevant with the Web content and thumb up notification message ".Notice is thumbed up it is, of course, also possible to further set to send
The mode of message further comprises mode of wechat notice and two kinds of Parallel Implementations of mail notification etc..It can be seen that with it is various types of
The number amount and type of the corresponding update operation of update request of type can be preconfigured.
In above-mentioned two ways, user need to only trigger once update request, and backstage i.e. can the multiple correspondences of automatic trigger
Update operation, for example, exemplified by thumbing up class update request, user, which need to only trigger, once thumbs up class update request, from the background can be from
It is dynamic to perform following two updates operation according to default request executing rule：(1) modification is with thumbing up in the corresponding network of operation
The dispaly state of appearance；(2) sent to user relevant with the Web content and thumb up notification message.Wherein, Section 1 update operation
Action type for display type, execution sequence is is first carrying out；The action type of Section 2 update operation is notification type, is held
Row order is in rear execution.Correspondingly, in this step, the update operation of Section 1 display type is first carried out, then performs second
The update operation of item notification type, to complete for the renewal process for thumbing up class update and asking.
In addition, in other realization methods, a update request it may also be desirable to user and perform multiple trigger action, often
Secondary trigger action corresponds to a update son request, and each update request corresponds to one or more updates and operates.For example,
Exemplified by commenting on class update request, user needs to perform following trigger action successively：(1) comment below Web content is clicked on to enter
Mouthful, so that the first computer room receives the first update son request included in comment class update request；(2) in comment input frame
Corresponding comment content is inputted, so that the first computer room receives the second update son request included in comment class update request；
(3) the submission entrance that comment is submitted in confirmation is clicked on, this to be submitted to comment on, and the first computer room is made to receive comment class update and is asked
The 3rd update son request included in asking.Every above-mentioned update son request corresponds at least one update and operates.For example, first
Update son request corresponds to the first update operation of display comment input frame；Second update son request corresponds to display comment content
Second update operation；3rd update son request correspond to modification Web content comment state the 3rd update operate and
It is operated to the 4th update to send a notification message with the relevant user terminal of the Web content.In this kind of mode, mesh will be performed
Identical multiple updates request be determined as a update request.It is also, in the present embodiment, each more for the ease of identification
New request is in advance the unique request mark of each update request distribution (for example, request ID).Correspondingly, asked in the update
Corresponding each update is asked and/or each update carries corresponding request mark in operation, in order to which basis is asked
Mark is asked to perform subsequent encapsulation operation.
Step S220：The corresponding multiple operation notes of multiple update operations are encapsulated as a piece of news according to execution sequence
Data.
Due to being assigned with unique request mark in advance for each update request in previous step, in this step,
Directly according to the request mark included in each update operation, each update operation corresponding to same update request is determined；
And it will be encapsulated as corresponding to the corresponding multiple operation notes of each update operation of same update request according to execution sequence
A piece of news data.
Specifically, it is multiple corresponding to update request when a update request only needs user to trigger once-through operation
Execution sequence between update operation can be both directly contained in the required parameter of update request, can also be pre-set and be deposited
Storage is in above-mentioned request executing rule；When a update request needs user to trigger multi-pass operation, update request institute is right
The multiple updates operation answered can also be determined further combined with the triggered time of multiple trigger action.For example, with above-mentioned comment class
Exemplified by update request, the execution sequence of the corresponding each update operation of each update request is according to corresponding update request
Trigger order determine.Correspondingly, the execution sequence of the first update operation is held earlier than the second update operation, the second update operation
Row order is earlier than the 3rd update operation.In addition, when same update request corresponds to multiple update operations, the plurality of update
Execution sequence between operation can be determined according to preset rules.For example, for the 3rd update son request, correspond to modification
3rd update of the comment state of Web content is operated and sent a notification message to the relevant user terminal of the Web content
The 4th update operation, the two update operation between execution sequences can be determined according to preset rules.
It can be seen that the present invention does not limit the specific method of determination of the execution sequence between each update operation.In addition,
Each update operation corresponds to an operation note, for recording the related letter such as operation object, the action type of update operation
Breath, in order to according to the operation note synchronization implementation update operation.In short, the present invention needs to be under the jurisdiction of according to request mark
Each operation note that each update operation of same update request is corresponding is encapsulated as a piece of news data.Also, at this
Ensure that each operation note is packaged according to execution sequence in message data, to prevent the generation of disorder phenomenon.
Step S230：In the storage file that message data storage is included to preset memory locations, preset and deposited according to this
Storage space puts included storage file and updates default message queue, to store message data into the message queue.
Specifically, message data can be stored into the default file folder under preset path, in being pressed from both sides by this document
Storage file records each message data, and default message queue is updated according to the storage file.Wherein, message queue
Can be various forms of message queues, as long as the caching function of message data can be realized.For example, can be distribution
Message queue to realize that the parallelization of data stores, promotes storage efficiency and memory capacity.It is each by what is generated in above-mentioned steps
Message data is stored into the message queue, for the second computer room according to each message data stored in message queue into line number
According to synchronization.Wherein, consumption terminal of second computer room as the message queue is responsible for consuming each message count in the message queue
According to, and realize that data are synchronous with the first computer room according to the message data of consumption.
During specific implementation, it is contemplated that the lasting progress of update operation in computer room persistently increases the size for causing storage file
It is long, it is therefore, whole according to default file in order to avoid generation the phenomenon that memory space inadequate, it is necessary to every prefixed time interval
The storage file that reason rule includes preset memory locations arranges, to save memory space.Specific arrangement rule can
It is flexibly set by those skilled in the art, in this example, it is assumed that at the first time the morning zero point of first day (be, for example),
First file (specifically include multiple files) of the storage file that preset memory locations are included corresponding to the first filename, will
The first file corresponding to first filename is renamed as the second filename, obtains the second text corresponding to the second filename
Part, the content phase of the file content and the first file corresponding to the first filename of the second file corresponding to second filename
Together.Afterwards, the 3rd file corresponding to the first filename, the file entitled first of the 3rd file are generated in preset memory locations
Filename, but be empty file when the 3rd file just generates and not comprising any content.After performing above-mentioned housekeeping operation, when again
When storing message data to preset memory locations, message data to be stored is write in the 3rd file, so as to avoid because of file
Memory space inadequate and lose message data.Similarly, the second time (being, for example, the morning zero point of second day), storage position is preset
Putting included storage file includes the 3rd file corresponding to the first filename, by the 3rd text corresponding to first filename
Part is renamed as the 3rd filename, obtains the 4th file corresponding to the 3rd filename, and corresponding to the 3rd filename
The file content of four files is identical with the content of the 3rd file corresponding to the first filename.Afterwards, given birth in preset memory locations
Into the 5th file corresponding to the first filename, entitled first filename of file of the 5th file, but the 5th file just generates
When and not comprising any content, be empty file.After performing above-mentioned housekeeping operation, when again to preset memory locations storage message count
According to when, message data to be stored is write in the 5th file, so as to avoid losing message count due to file storage is insufficient
According to.It can be seen that by aforesaid operations, constantly by original storage file renaming, and new storage file is generated, so that
Subsequent message data is write in new storage file.In addition, after certain interval of time, it can also be to each text after renaming
Operation is deleted or removed to part, to save disk space.For example, it is assumed that the original document of preset memory locations storage is
A.log files after being then spaced preset time, by original a.log files renamed as b.log files, and regenerate one
Empty a.log files, so that subsequent message data is stored in the empty a.log files.Correspondingly, root in this step
, it is necessary to which read to represent file change conditions is during the storage file new information queue included according to preset memory locations
It unites notification message, determines the storage file after the arrangement that preset memory locations are included according to the notifications message, and according to
Storage file new information queue after arrangement.That is, after the name of file changes, read out in order to prevent
It is wrong, it is necessary to subscribe to represent the notifications message of file change conditions, to understand the situation of change of filename in time, from
And the file according to corresponding to the filename after variation is come new information queue.Certainly, obtained except through notifications message
Outside the mode for knowing filename situation of change, the text for each storage file that preset memory locations are included can also be periodically checked
Part name change conditions.
Step S240：Second computer room carries out data synchronization according to each message data stored in message queue.
Specifically, first, the second computer room obtains a piece of news data in message queue, determines what is included in message data
Multiple operation notes；Then, create and the corresponding update affairs of message data；Wherein, in the update affairs comprising it is multiple with
The multiple operation notes included in message data update operation correspondingly；Finally, update affairs execution and message are passed through
The corresponding data simultaneously operating of data.
" the display shape for operating corresponding Web content is changed and thumbs up for example, it is assumed that including in a piece of news data
State " and " sent to user relevant with the Web content and thumb up notification message " two operation notes, correspondingly, create and are somebody's turn to do
The corresponding update affairs of message data, and update to include to perform in affairs and " change and thumb up the corresponding network of operation
First update of the dispaly state of content " is operated and " thumbed up for performing to user relevant with Web content transmission logical
Know message " second update operation.During specific execution, only when the first update included in the update affairs is operated with second more
When new operation is carried out successfully, the affairs are just submitted；When the first update operation included in the update affairs and/or the second update
When operation performs failure, the rollback affairs.By way of affairs, it is ensured that the uniformity of the data in database avoids
