The data processing method the following steps are included:
Step S10 lines up to obtain target message in 121 from first message；
Under high concurrent environment, due to having little time synchronization process, request is often blocked, and directly results in countless rows
Lock table lock or even last-minute plea can accumulate excessively, to trigger mistake.By using in message team, asynchronous process may be implemented
Request, alleviates the pressure of system.It is stored in message in Message Queuing 120 to consume by asynchronous engine server 130, and is sent to
Micro services recipient 140 executes.
First message lines up 121 target messages for receiving and saving the transmission of called side 110 one by one, and according to first in first out
Mode obtains target message for asynchronous engine server 130.It is born in this embodiment, it is preferred that first message lines up 121
Duty saves target message, and target message is lined up to obtain in 120 and consumes this by asynchronous 130 active of engine server from first message
Target, when asynchronous engine server 130 initiates to call according to the message of the executive condition of target message in message team, according to
The time interval being previously set, the case where periodically listening to the message channel of Message Queuing 120.Once it was found that have message transmission into
Come, message will be obtained from message channel.
Target message itself carries the task node information of its corresponding information node, and a message itself includes at least
One task node forms target message by the execution logic between multiple tasks node when including multiple tasks node
Complete logical function.The multiple tasks node combined with tree is carried in target message, which contains
Logical relation between each task node.Meanwhile its corresponding, method parameter is also carried in target message, micro services connect
Mouthful, rollback interface and executed Task-list etc..Wherein micro services interface refers to the micro services recipient for executing the target message
140 calling interface, rollback interface refer to the rollback interface of the micro services recipient 140 when cancelling the target message, have executed
Task-list has recorded the information such as the corresponding execution state of the target message.
Step S11 sends the target message to log database 150, and the target message includes job node
Information；
Line up after getting target message in 121 from first message, reads the job node letter that target message carries
Breath obtains the execution information of target message, and target message is sent to log database 150.Start to hold in entire messaging service
Before row, the entire flow that tree is stored in log database 150 defines table, and it includes dynamic language that entire flow, which defines table,
Specific service process and the node-classification, including starting point, condition, rollback etc. for saying description, have recorded holding for multiple target messages
Row process.In addition, log database 150 also preserves messages application state table, messages application state table is with the preservation of chain sheet form
The number of retries of the task node, the task node that have executed retries time, execution state etc., and log database 150 also saves
There is execution context, executes context and be used to preserve the required parameter for calling micro services recipient 140.Log database 150
After having received target message, the task node information for including in target message is inserted in messages application state table, is worked as with record
The status information of preceding target message.
Step S12, from the micro services interface and the target message of target message described in the task node acquisition of information
Required parameter；
It reads the task node information that target message carries and obtains micro services interface and request corresponding to target message
Parameter can find the micro services recipient 140 of performance objective message by micro services interface, by required parameter in incognito
Business recipient 140 sends call request, so that micro services recipient 140 receives the target message.Required parameter, which contains, asks
It seeks information and calls the key information etc. of micro services recipient 140.
The required parameter is sent to corresponding micro services recipient 140 according to the micro services interface by step S13,
So that the micro services recipient 140 executes the target message；
After getting the corresponding micro services interface of target message and required parameter, required parameter is sent out according to micro services interface
It send to corresponding micro services recipient 140, after micro services recipient 140 passes through call request, receives target message and execute mesh
Mark message.
Its implementing result can be fed back to asynchronous engine server 130 after performance objective message by micro services recipient 140.
Specifically, micro services recipient 140 periodically sends feedback result to asynchronous engine server 130 in preset time interval.
The feedback result that micro services recipient 140 sends has different forms according to different executive conditions.In the present embodiment, when
When micro services recipient 140 is successfully processed target message, feedback result is to run succeeded；When micro services recipient 140 is due to net
When situations such as network is abnormal or receives time-out fails to receive target message, feedback result is that reception is abnormal, when micro services receive
When 140 processing failure of side, then feedback result is processing failure.In other embodiments, the feedback that micro services recipient 140 sends
Result can also use digital representation, be not limited herein.
Step S14, receives the feedback result of the micro services recipient 140, and according to the feedback result to the day
Will database 150 sends first kind Status Change notice, so that the log database 150 changes appointing for the target message
Business nodal information.
After asynchronous engine server 130 receives the feedback result that micro services recipient 140 sends, according to feedback result to day
Will database 150 sends first kind Status Change notice.After asynchronous engine server 130 receives feedback result, first to feedback
As a result it is analyzed.When analyzing feedback result is to run succeeded, then asynchronous engine server 130 issues first kind state
Notification of Changes be change target message execution state be complete (or with digital representation, as 1), be when analyzing feedback result
When receiving abnormal, then the first kind Status Change notice that asynchronous engine server 130 issues is the execution shape of change target message
State be it is abnormal (or use digital representation, such as 2), when analyzing feedback result as processing failure, then asynchronous engine server 130
The first kind Status Change notice of sending is to change the execution state of target message as to rollback.
It should be noted that parameters are provided with initial shape in messages application state table in log database 150
State, such as executing the original state of state is to be not carried out (number 0), number of retries is 0 or preset value (being greater than 0), when retrying
Between be empty (or number 0) etc..When the first kind Status Change notice that database receives is the execution shape of change target message
State is when completing, then to be changed to complete to the execution state of target message in messages application list, other parameters value default.Work as number
The first kind Status Change notice received according to library be the execution state of change target message when being abnormal, then messages application list
In exception is changed to the execution state of target message, the first kind Status Change notice received when database is change target
The execution state of message is then to be changed to the execution state of target message to rollback in messages application list when rollback.This
Outside, every execution is equal to the parameters of target message in the messages application list in log database 150 once to target message
Need to obtain corresponding change, the situation processed of real-time tracing target message, to guarantee that called side 110 and micro services receive
The data consistency of side 140.
In the present embodiment, target message is stored in first message and lines up 121 total, asynchronous engine servers 130 from first
Target message is obtained in Message Queuing 121, and by the task node information preservation of target message and target message in daily record data
In library 150, micro services interface and required parameter are obtained by the nodal information of target message, call corresponding micro services recipient
140 processing target message, and the feedback result of real-time reception micro services recipient 140 send first kind shape according to feedback result
State Notification of Changes to log database 150, log database 150 notifies change target message in time according to first kind Status Change
Task node information.For the present embodiment by one log database 150 of setting, the execution disposition of all target messages is equal
It is managed and is recorded by a log database 150, can guarantee the final consistency of data.
Referring to Fig. 3, Fig. 3 is the flow diagram of the second embodiment of data processing method of the present invention.In the present embodiment,
It is further comprising the steps of after step S14:
Step S15, is searched from the log database 150 and load and execution state is abnormal or to rollback to from
Manage message；
When the feedback result that asynchronous engine server 130 analyzes micro services recipient 140 is to receive abnormal or processing
When failure, the first kind Status Change notice that asynchronous engine server 130 issues is that the execution state of change target message is different
Often or to rollback.Either executing state is abnormal still to rollback, illustrates the untreated success of target message.When execution shape
When state is abnormal, illustrate to fail into due to Network Abnormal or reception time-out etc. when micro services reciever receives target message
Function receives target message, then needs to carry out such target message to be re-transmitted to micro services recipient 140.When the state of execution
When rollback, to illustrate micro services reciever processing target message failure, in order to keep the consistency of distributed data, need by
The message of processing failure carries out rollback, executes process to cancel.It therefore, is mesh abnormal or to rollback for executing state
Mark message, which needs to wait, to be further processed.
Needing to wait the target message that is further processed is message to be processed, and asynchronous engine server 130 is from daily record data
The message to be processed for searching and loading the condition of satisfaction is obtained in library 150, to be handled again.
The message to be processed is sent to second message and lines up 122, and sent out to the log database 150 by step S16
The second class Status Change is sent to notify, so that the log database 150 changes the task node information of the target message.
Asynchronous engine server 130 sends message to be processed after loading message to be processed in log database 150
Line up 122 preservations to second message.It is to line up the identical Message Queuing of 121 functions with first message that second message, which lines up 122,
120, it is located in 120 server of Message Queuing.Second message is lined up 122 and is sent out for saving asynchronous engine server 130
The message to be processed sent.Message to be processed is sent to after second message lines up 122 by asynchronous engine server 130, due to
Processing message execution state change, therefore, asynchronous engine server 130 also need send the second class Status Change notify to
Log database 150, so that log database 150 changes the task node information of the corresponding target message of message to be processed.
Execution state when message to be processed is loaded into asynchronous engine server 130 is exception, is disappeared due to be processed
Breath is sent to after second message lines up 122 in the state retransmitted, and therefore, the second class Status Change notice is held for change
Row state is just in abnormality processing, and its number of retries needs on the basis of existing number of retries plus 1 or subtracts 1.When retrying
When the default value of number is greater than 0, that is, the number of retries for presetting each target message is n times, often retries primary need
1 is subtracted on default value, if target message repeatedly sends still unsuccessful, when number of retries is equal to 0, then no longer to the target message
It is retransmitted.When the default value of number of retries is equal to 0, often retries primary needs and add 1 on default value, if target message
Repeatedly transmission is still unsuccessful, when number of retries reaches upper limit value, then no longer retransmits to the target message.
Therefore, message to be processed, which also needs its number of retries to meet preset rules, to be added by asynchronous engine server 130
It carries, if meeting preset rules can be loaded into asynchronous engine server 130, if being unsatisfactory for preset rules, that is, illustrates that it is retried
Number has reached upper limit value and has not needed again to handle it, asynchronous that server is caused to screen out such execution failure news.
In addition, even if the execution state of target message is abnormal, and number of retries is full for the target message regularly sent
Sufficient preset rules, it is also necessary to which consider target message retries whether the time meets the requirements.Generally, the mesh regularly sent is not needed
Mark message, retrying the time is defaulted as without (or 0), the object time for needing to regularly send, retry the time can according to by
Asynchronous engine server 130 is configured according to preparatory principle.When asynchronous engine server 130 receives micro services recipient
When 140 feedback result, when analysis feedback result is exception and causes due to receiving supermarket, then first kind Status Change is notified
In, it sets the time that retries of target message to preset time (such as 5 minutes), i.e., is retried again after 5 minutes.At this point, day
In will database 150, is calculated with the timer for retrying association in time and retry the time, can dynamically show residue by retrying the time
Time, or when in the preset time, time showing 1 is retried, when reaching preset time, retrying time showing is 0.For
The message to be processed for needing to regularly send, the second class Status Change notice that asynchronous engine server 130 is sent execute for change
State is and to retry the time just in abnormality processing and reset according to preset time, and its number of retries needs are retried existing
Add 1 on the basis of number or subtracts 1.
In addition, execution state when message to be processed is loaded into asynchronous engine server 130 be when rollback, due to
Message to be processed is sent to the state that rollback is in after second message lines up 122, at this point, the second class Status Change notice is change
Execution state is just in rollback, and number of retries is reset according to preset time.
Referring to Fig. 4, Fig. 4 is the flow diagram of the 3rd embodiment of data processing method of the present invention.In the present embodiment,
It is further comprising the steps of after step S16:
Step S17 lines up to obtain the message to be processed in 122 from the second message, and reads described to be processed disappear
Task node information in breath；
Step S18 judges the execution state of message to be processed described in the task node information for just in abnormality processing
Still just in rollback；
Step S19, if the execution state is just in abnormality processing, return step S12；
Step S20, if the execution state is to obtain corresponding rollback from the task node information just in rollback
Interface and required parameter, and call corresponding micro services recipient 140 to carry out according to the rollback interface and the required parameter
Revocation processing, and return step S14.
Second message lines up to save message to be handled in 122, and the processing of message to be processed continues by asynchronous engine service
Device 130 is completed.According to preset time interval, asynchronous engine server 130 periodically lines up to obtain in 122 from second message
Target message to be processed, and read the task node information of message to be processed.It should be noted that the task section of message to be processed
Point information can be obtained from log database 150, can also be obtained from the task node information that message to be processed itself carries
It takes.And preferably, the information of target message itself carries task node information and the record in log database 150 is protected at any time
Hold synchronization.
Further, judge in task node information, the execution state of message to be processed be for just in abnormality processing or
Just in rollback, if just in abnormality processing, return step S12 obtains the micro services interface and required parameter of message to be processed, root
Corresponding micro services recipient 140 is found according to micro services interface, is handled by required parameter request call micro services recipient 140
Message to be processed, and the feedback result of the transmission of micro services recipient 140 is received, first kind Status Change is sent according to feedback result
It notifies to log database 150, log database 150 changes execution state, number of retries according to feedback result, retries the time etc.
Parameter information.For example, it is to complete that then log database 150, which will execute Status Change, if instead when feedback result is to run succeeded
Presenting result is to receive exception, then it is abnormal that log database 150, which will execute Status Change, if feedback result is processing failure,
It is to rollback that log database 150, which will execute Status Change,.
If just in rollback, then obtained in task node information in asynchronous engine server 130 corresponding rollback interface and
Required parameter, and call corresponding micro services recipient 140 to carry out to message to be processed according to rollback interface and required parameter
The process of generation carries out revocation processing, and revocation finishes return step S14, and revocation result feeds back to asynchronous engine.In addition, if feedback
As a result to complete, then log database 150 will execute Status Change for rollback completion, if feedback result is processing failure or different
Often, then log database 150 will execute Status Change as rollback failure.
Referring to Fig. 5, Fig. 5 is the system framework schematic diagram of the first embodiment of data processing system of the present invention.This implementation
In example, data processing system includes called side 110, Message Queuing 120, log database 150, micro services recipient 140 and different
Walk engine server 130, wherein
