In a Distributed System, there is the upstream and downstream system for the relationship of directly invoking to need to ensure the power of service call
Etc. property.In application system, the characteristics of idempotent operation be arbitrarily performed a plurality of times caused by influence with once execute
Influence identical, in a distributed system, same request parameter is interaction is once with the multiple effect of interaction between system.
Above-mentioned characteristic is known as idempotence.
Idempotence is kept to be very important in systems.It is as shown in Figure 1 that one kind not meeting the case where idempotence requires.
In step 102, upstream business system sends service request to service system.At step 104, service system is accepted
The request.In step 106, service system upstream traffic system transmission accepts success message, but the message is not sent
Success.In step 108, upstream business system retransmits service request to service system.In step 110, service handling
System accepts the request again.In step 112, service system upstream traffic system return accepts success message.This
Same business is resulted in be accepted twice.
By taking payment transaction as an example, when upstream business system initiates payment request to service system, service handling system
System can accept delivery operation according to the request, to deduct assets from the account of user, if deducted successfully, account balance
Reduce corresponding value；If deducting failure, account balance is constant, while service system can be returned with upstream traffic system
Pay the prompt message of failure.It is a kind of that typically payment request is correctly handled by service system, but business by
The handling result that reason system returns fails to return to upstream business system due to network etc..Upstream business system can at this time
Payment request can be sent to service system again by modes such as refresh operation interfaces, service system executes again
Deduct the operation of account assets.It is repeated and has been accepted twice which results in same business, cause user's loss of assets.
System switching refers to replacing the first system (i.e. legacy system) with second system (i.e. new system), will be accepted in legacy system
Service switching to new system on the process that accepts.Sometimes, after legacy system being switched to new system, new system it is unstable or
There is exception, in order to avoid influencing business, it is also possible to new system be switched back into legacy system again, switched again after new system stabilization
To legacy system.In new, legacy system handoff procedure, if a business accepts success via new system, but legacy system is not
It can know that new system has accepted success, it is likely that cause legacy system to repeat to accept the business, if legacy system is also successfully accepted
The business can then cause to violate idempotence requirement.
In view of the above-mentioned problems, this specification embodiment provides the idempotent control method in a kind of net system switching process, such as Fig. 2
Shown, the above method may include following steps 202 and step 204：
Step 202：In net system switching process, the call request that idempotent verifies is sent to second system, the calling is asked
Seek carrying business odd numbers；
Step 204：Determined whether to accept the corresponding business of the business odd numbers according to the idempotent check results of second system,
Wherein, the idempotent check results of second system are used to characterize the idempotent control whether the business odd numbers is successively inserted into second system
Record.
The scheme of this specification embodiment first goes the idempotent for calling second system to sentence when the first system accepts a business
Disconnected service, judges to service and judges whether the business accepted in second system by the idempotent, to determine that the first system is
It is no to accept the business, it avoids the first system and second system repeats to accept same item business, ensured in net system switching process
Global idempotence between each system.
In general, it may include following below scheme during service handling：Business of the upstream business system to the business that accepts
Receiving system sends service request, business odd numbers is carried in service request, for uniquely determining a business.Service system
Business is accepted after receiving service request, and the information that the business has been accepted is added to the idempotent in database and is controlled
In record, whether idempotent control record is accepted for record traffic.After accepting successfully, business can be generated according to business odd numbers
Document, and business paper is committed to database；Meanwhile service system can return to an industry with upstream traffic system
Business accepts success message, to notify the upstream business system business to accept success.
In step 202, the effect of idempotent verification is whether checking system had accepted the corresponding business of business odd numbers.
It was accepted in second system due to being possible to this business, so need to provide an idempotent verification service by second system, the
One system is by calling the idempotent of second system to verify service, so as to know whether second system had accepted corresponding industry
Business.Business odd numbers can be carried by calling in the call request of second system idempotent verification service, second system is receiving calling
After request, business odd numbers therein can be extracted, and idempotent verification is executed according to the business odd numbers.
In step 204, judge second in such a way that business odd numbers to be inserted into the idempotent control record of second system
Whether system accepted corresponding business.Why will be by the way of being inserted into, rather than directly inquire business odd numbers correspondence
Business paper whether there is in idempotent control record, be because in some cases, second system has other thread to exist
The business being accepted, but business does not accept completion also to not submit, other threads can not inquire business paper, so even if
The business paper is not present from idempotent control record queries, can not illustrate that the business paper is not accepted in new system.Therefore,
This specification embodiment can more accurately judge whether business is accepted by way of insertion, and it is general to reduce erroneous judgement
Rate.
After business odd numbers is inserted into the idempotent control record of second system, in fact it could happen that any one in following three kinds of situations
Person：
Situation one：
The idempotent control that business odd numbers is inserted into second system records successfully.If be inserted into successfully, illustrate second system herein
It was not carried out insertion operation before, was currently inserted into be inserted into for the first time.That is, second system did not accept the business.
Therefore, the first system should accept the corresponding business of business odd numbers.After service handling success, the first system can also notify
The corresponding service handling success of the upstream business system business odd numbers.
Situation two：
Business odd numbers is inserted into the idempotent control record failure of second system, but does not find the business odd numbers in second system
Corresponding business paper.Such case illustrates that the first system had called up the idempotent judgement service of second system before this,
And idempotent control record is inserted into successfully, but the follow-up acceptance procedure of second system is abnormal, and does not accept success, upstream business system
System is retried again, retries rear the first system and the idempotent of new system is called to judge service again.At this point, the first system should be by
Manage the corresponding business of business odd numbers.After service handling success, the first system can also notify the upstream business system business
The corresponding service handling success of odd numbers.
Situation three：
Business odd numbers is inserted into the idempotent control record failure of second system, and the business odd numbers pair is found in second system
The business paper answered.Such case illustrates that the business has accepted success in second system, and the first system no longer needs to remain seized of.
Therefore, the first system can directly notify the corresponding service handling success of the upstream business system business odd numbers.
In one embodiment, the first system can first call local idempotent to verify service to look into when accepting business
Ask whether the business had accepted locally, it is out-of-date only not accepted in local when business, just accepts corresponding business, to avoid
Business is locally repeating to accept.Specifically, the step of accepting business odd numbers corresponding business include：It is executed according to business odd numbers
Local idempotent verification；Determine whether to accept the corresponding business of the business odd numbers according to local idempotent check results, wherein this
The idempotent check results on ground are used to characterize whether the business odd numbers to be successively inserted into local idempotent control record.
After business odd numbers is inserted into local idempotent control record, in fact it could happen that any one in following two situations：
Situation one：
Business odd numbers is inserted into local idempotent control and records successfully.Such case illustrates that the local business odd numbers that do not accepted corresponds to
Business, therefore, the first system should accept the business.After service handling success, the first system can also notify upstream industry
The corresponding service handling success of the business system business odd numbers.
Situation two：
Business odd numbers is inserted into local idempotent control record failure.It is corresponding that such case illustrates that local accepted business odd numbers
Business, therefore, the first system no longer need to remain seized of, and the first system can directly notify the upstream business system business odd numbers pair
The service handling success answered.
In one embodiment, if the idempotent control that business odd numbers is inserted into second system records successfully, second system can be with
Idempotent is returned to the first system and verifies success message, to notify the first system to accept business.If business odd numbers is inserted into second system
Idempotent control record failure, second system can to the first system return idempotent verify failed message, to notify the first system
Without accepting business.
In one embodiment, if the first system or second system successfully accept business, the first system can be upstream
Operation system returns to " idempotent repeating transmission " result code, for notifying upstream business system business to accept success.
Corresponding control sequential figure is as shown in Figures 3 to 5.Embodiment shown in Fig. 3 includes the following steps：
Step 302：Upstream business system sends service request to the first system.
Step 304：The first system calls the idempotent verification service of second system.
Step 306：The idempotent that business odd numbers is inserted into second system by second system controls record.
Step 308：If be inserted into successfully, or fail if be inserted into, and does not find the business odd numbers in second system
Corresponding business paper, second system send idempotent to the first system and verify success message.
Step 310：The first system executes local idempotent verification.
Step 312：Business odd numbers is inserted into local idempotent control and recorded successfully by the first system, and the first system accepts business.
Step 314：After the first system is accepted successfully, upstream traffic system returns to " idempotent repeating transmission " result code.
Embodiment shown in Fig. 4 includes the following steps：
Step 402：Upstream business system sends service request to the first system.
Step 404：The first system calls the idempotent verification service of second system.
Step 406：The idempotent that business odd numbers is inserted into second system by second system controls record.
Step 408：If be inserted into successfully, or fail if be inserted into, and does not find the business odd numbers in second system
Corresponding business paper, second system send idempotent to the first system and verify success message.
Step 410：The first system executes local idempotent verification.
Step 412：Business odd numbers is inserted into local idempotent control record failure, the first system upstream traffic by the first system
System returns to " idempotent repeating transmission " result code.
Embodiment shown in fig. 5 includes the following steps：
Step 502：Upstream business system sends service request to the first system.
Step 504：The first system calls the idempotent verification service of second system.
Step 506：The idempotent that business odd numbers is inserted into second system by second system controls record.
Step 508：If being inserted into failure, and the corresponding business paper of business odd numbers is found in second system, second
System sends idempotent to the first system and verifies failed message.
Step 510：The first system upstream traffic system returns to " idempotent repeating transmission " result code.
This specification embodiment also provides the idempotent control method in a kind of net system switching process, as shown in fig. 6, the side
Method may include following steps 602 and step 604：
Step 602：In net system switching process, the call request for the idempotent verification that the first system is sent, the tune are received
With request carrying business odd numbers；
Step 604：Local idempotent verification is executed according to the business odd numbers, and idempotent check results are sent to the first system
System, so that the first system determines whether to accept the corresponding business of the business odd numbers according to the idempotent check results；Wherein, originally
The idempotent check results on ground are used to characterize whether the business odd numbers to be successively inserted into local idempotent control record.
The second system of this specification embodiment can provide idempotent and judge service, for receiving the first of service request
System is called, to make the first system know whether second system had accepted the business, to avoid the first system weight
Same business is accepted again, has ensured the global idempotence between each system in net system switching process.
Second system can extract business odd numbers therein, and according to the business odd numbers after receiving call request
Execute idempotent verification.In step 604, judged in such a way that business odd numbers to be inserted into the idempotent control record of second system
Whether second system accepted corresponding business.Can more accurately be judged by way of insertion business whether by by
Reason reduces probability of miscarriage of justice.
After business odd numbers is inserted into the idempotent control record of second system, in fact it could happen that any one in following three kinds of situations
Person：
Situation one：
The idempotent control that business odd numbers is inserted into second system records successfully.If be inserted into successfully, illustrate second system herein
It was not carried out insertion operation before, was currently inserted into be inserted into for the first time.That is, second system did not accept the business.
Therefore, second system, which can send to characterize the business odd numbers and be inserted into local idempotent control to the first system, record successful the
One idempotent check results, so that the first system accepts the business.
Situation two：
Business odd numbers is inserted into the idempotent control record failure of second system, but does not find the business odd numbers in second system
Corresponding business paper.Such case illustrates that the first system had called up the idempotent judgement service of second system before this,
And idempotent control record is inserted into successfully, but the follow-up acceptance procedure of second system is abnormal, and does not accept success, upstream business system
System is retried again, retries rear the first system and the idempotent of new system is called to judge service again.At this point, second system can be to
The first system sends the local idempotent control of the characterization business odd numbers insertion and records successful first idempotent check results, so that
The first system accepts the business.
Situation three：
Business odd numbers is inserted into the idempotent control record failure of second system, and the business odd numbers pair is found in second system
The business paper answered.Such case illustrates that the business has accepted success in second system, and the first system no longer needs to remain seized of.
Therefore, second system can be sent to the first system characterizes the business odd numbers is inserted into local idempotent control record failure the
Two idempotent check results, to notify the first system without accepting the business.In addition, the first system is receiving the verification of the second idempotent
As a result after, the corresponding service handling success of business odd numbers described in upstream business system can also be notified.
As shown in fig. 7, being the overview flow chart of the idempotent control method of this specification one embodiment.
In a step 702, the first system receives service request.
In step 704, the first system calls new system idempotent to judge service.
In step 706, second system receives idempotent and judges to ask.
In step 708, second system is attempted to be inserted into idempotent control record, is inserted into and successfully thens follow the steps 710；It is inserted into and loses
It loses and thens follow the steps 716.
In step 720, second system returns to idempotent to the first system and verifies success message.
In step 712, the first system executes local idempotent and judges.Idempotent control record, which is inserted into, successfully to be thened follow the steps
714, insertion unsuccessfully thens follow the steps 722.
Step 714：The first system accepts business.
Step 716：Second system judges that service handling document whether there is, and there is no then follow the steps 718；In the presence of then holding
Row step 720.
Step 718：Second system returns to idempotent to the first system and verifies success message, and executes step 712.
Step 720：Second system returns to idempotent to the first system and verifies failed message, and executes step 722.
Step 722：The first system does not continue to accept the business, and executes step 724.
Step 724：The return of the first system upstream traffic system accepts success message.
