Description

A kind of distributed transaction communication means, system and device

Technical field

The application relates to Internet communication technology field, particularly to a kind of distributed transaction communication means, system and device.

Background technology

Along with making rapid progress of Internet communication technology, some large-scale internet systems, due to reasons such as business are complicated, can go out Now a large amount of distributed transaction scenes.Distributed transaction includes being positioned at the affairs participant on the different nodes of distributed system, money Source server, task manager etc. can interact to realize a common target.

In prior art, the different nodes of distributed system interact to realize the communication means bag that distributed transaction mainly uses Include: XA two-phase commitment protocol.Use in the distributed system of XA two-phase commitment protocol, there is a node as coordination Person, other nodes are as participant.The first stage of XA two-phase commitment protocol is the voting stage: coordinator's node is to all Participant's node asks whether with the submission operation of successful execution Current transaction branch, and to start waiting for the sound of each participant's node Should；The inquiry that each participant's node response coordinator's node is initiated, the information whether can successfully submitted to by this transaction branch is fed back Issue coordinator, but the most really perform affairs.Second stage is carried out the stage: coordinator's node returns according to all participant's nodes The response message returned, notifies all participant's nodes, submits to or rollback affairs with acting in agreement in all branches.Participant Node sends, to coordinator's node, the message that affairs are submitted to or rollback completes；Coordinator's node receives all participant's node feeding back After completion message, end transaction.Concrete, when coordinator's node is all successfully from the response message that all participant's nodes obtain Time, coordinator's node sends the request of " being submitted to " to all participant's nodes；If arbitrary participant's node is in the first stage The response message returned is unsuccessful, or coordinator's node cannot obtain all participants before the inquiry time-out of first stage During the response message of node, coordinator's node sends the request of " rolling back action " to all participant's nodes.

During realizing the application, inventor finds that in prior art, at least there are the following problems:

When utilizing XA two-phase commitment protocol to realize distributed transaction in prior art, real execution affairs are second stage. And must etc. all of participant's node all whether this transaction branch can successfully be submitted to information feedback issue coordinator after, Second stage could be entered, namely real execution submits operation to.Therefore, once have arbitrary transaction branch not have in the first stage and Time whether this transaction branch can successfully be submitted to information feedback issue coordinator, all of participant's node be required for wait, And enter blocked state.Therefore, the communication means of XA two benches agreement cannot realize high performance distributed transaction communication.

Detailed description of the invention

The embodiment of the present application provides a kind of distributed transaction communication means, system and device.

For the technical scheme making those skilled in the art be more fully understood that in the application, below in conjunction with in the embodiment of the present application Accompanying drawing, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is only It is some embodiments of the present application rather than whole embodiments.Based on the embodiment in the application, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, all should belong to the scope of the application protection.

Implementing of the embodiment of the present application is described in detail below with several specific examples.

In the embodiment of the present application, a distributed transaction system can include one or more task manager (Transaction Manager, TM), one or more explorer (Resource Manager, RM), the several part of client, also Other affairs participant can be included.Wherein, task manager, namely the coordinator of affairs, it is responsible for coordinating distributed transaction； Explorer is responsible for the management of resource；Resource can include data base and message-oriented middleware；Client is usually transaction initiator.

Hereinafter the embodiment of the application a kind of distributed transaction communication means is first introduced.In conjunction with accompanying drawing 1, this embodiment includes:

S100: client sends to task manager and opens transaction message.

In the embodiment of the present application, if needing to open affairs, it is possible to use client sends to task manager and opens affairs Message.Concrete, such as client performs update/insert/delete SQL statement by JDBC.Here JDBC (Java Data Base Connectivity, java data base connects) it is how Java language accesses data for specification client-side program The application programming interfaces in storehouse, it is provided that the method for data in such as inquiry and more new database.Further, SQL here (Structured Query Language) refers to SQL, is a kind of programming language, the standard in data base Data query language.

Further, task manager can open successful message to client feedback affairs, and described message can comprise the overall situation Affairs ID, described global transaction ID can be as the mark of this business communications process.

Additionally, typically before sending unlatching transaction message, the explorer of client and its correspondence can be first to affairs pipe Reason device sends registration message, carries out the registration of client and explorer.

S200: client processes transaction message to first resource manager transmission.

After client successfully starts affairs, client can carry out local matter, sends to first resource manager and performs Transaction message.

Further, first resource manager described here can refer to the explorer of client deployment.And it is distributed at one In system, a client can dispose a corresponding explorer, it is also possible to disposes multiple explorer.

Further, described first resource manager can be and client explorer in a process.

S300: first resource manager sends registration transactions branch message to task manager.

In the embodiment of the present application, the associative operation of one affairs when client executing.Client can be after local matter be opened By corresponding first resource manager to task manager registration transactions branch；Accordingly, task manager can be to the first money The message that source manager feedback transaction branch succeeds in registration, contains transaction branch ID, described transaction branch ID and makees in described message Mark for this transaction branch communication process.

In S200, client is after first resource manager transmission processes transaction message, and described first resource manager can be registered One or more transaction branch, the number of transaction branch can determine according to concrete affairs.In actual application, a general distribution Formula affairs at least two transaction branch, otherwise lose the meaning of distributed transaction.

Further, client can also be called preset service by the way of sending message call to preset service and perform thing here Business operation, described message call includes the global transaction ID currently opening affairs.Accordingly, described preset service can dispose one Individual with described preset service at the explorer of same process, it is also possible to dispose multiple with described preset service in same process Explorer.And when client needs to call preset service execution transaction operation, preset service can first call Secondary resource Manager sends registration message to task manager；Accordingly, task manager feeds back Secondary resource pipe to Secondary resource manager After the message that reason device succeeds in registration, preset service can call Secondary resource manager and divide to task manager transmission registration transactions Propping up message, this transaction branch can be as global transaction a transaction branch.

Further, preset service here can include remote procedure call protocol (Remote Procedure Call Protocol, RPC), but the embodiment of the present application is not limited thereto.

Further, Secondary resource manager here refers to and described preset service explorer in a process.

S400: transaction branch described in first resource manager processes, and return transaction branch state according to result.

In the embodiment of the present application, after step S300, after first resource manager successful registration transaction branch, in the first thing Under business pattern, in conjunction with accompanying drawing 2, transaction branch described in first resource manager processes, and return transaction branch according to result State specifically includes:

S411: first resource manager judges whether described transaction branch can perform.

S412: when described being judged as YES, performs described transaction branch, and records the state before described transaction branch performs and institute State the state after transaction branch performs, return successful transaction bifurcation state.

S413: when described being judged as NO, return unsuccessfully transaction branch state.

Further, when described being judged as YES, first resource manager performs current local matter.Specifically include:

1, Save Undo refers to preserve front mirror image, i.e. preserves the state before affairs perform.

2, Exec SQL refers to really perform affairs.

3, mirror image after Save Redo refers to preserve, i.e. preserves the state after affairs perform.

4, Local Commit refers to submit affairs to.

Return successful transaction bifurcation state.

When described being judged as NO, return unsuccessfully transaction branch state.

As a example by " A account number is to B account number remittance money " these affairs, in step S300, first resource manager needs to affairs pipe Reason device two transaction branch of registration.The execution process of the most above-mentioned local matter, may include that

Article 1, the execution process of the local matter of transaction branch includes:

Will the remit money remaining sum of front A account of Save Undo is saved in daily record, can be figuratively to preserve the remaining sum in A account number.

A account number is i.e. done subtraction by Exec SQL.

Save Redo is i.e. saved in the result of subtraction in daily record, can be figuratively that the result of subtraction is preserved A In account number.

Local Commit i.e. this locality completes A account number to B account number remittance money.

The execution process of the local matter of Article 2 transaction branch includes:

Will the remit money remaining sum of front B account of Save Undo is saved in daily record, can be figuratively to read the remaining sum in B account number.

B account number is i.e. done add operation by Exec SQL.

Save Redo is i.e. saved in the result of add operation in daily record, can be figuratively that the result of add operation is saved in In B account number.

Local Commit i.e. this locality completes A account number to B account number remittance money.

Further, if client call preset service, Secondary resource manager is receiving the thing of task manager feedback After the message that business branch succeeds in registration, local matter can be performed.

Under the second transaction mode, in conjunction with accompanying drawing 3, transaction branch described in first resource manager processes, and according to processing knot Fruit returns transaction branch state and specifically includes:

S421: first resource manager judges whether described transaction branch can perform.

S422: when described being judged as YES, the default resource of reserved described transaction branch, and arrange default to described transaction branch Mark, returns successful transaction bifurcation state.

S423: when described being judged as NO, return unsuccessfully transaction branch state.

When described default mark can ensure that if other apply Current transaction to be operated, find that this default mark then returns mistake Lose.Therefore, even if when processing local matter, really perform Current transaction, when also can guarantee that follow-up real execution, Affairs can be completed.

As a example by " buying the lottery ticket of 10 yuan by C account, this lottery ticket includes 2 numerals, and each numeral is 5 yuan ", this transaction packet Include two transaction branch.First transaction branch is: buy 5 yuan of first digit button；Second transaction branch is: buy the 5 yuan of two-digit button,

The processing procedure of first transaction branch specifically includes:

Whether the first task manager needs the remaining sum judging in C account more than or equal to 5 yuan.When described being judged as YES, resource pipe Reason device only need to first carry out the operation of resource reservation, namely reserved currently 5 yuan in C account, and these 5 yuan can be as reserved resource. And default mark is set to this Current transaction, described default mark can ensure that if other application to operate this 5 yuan of reserved resources Time, find that this default mark then returns failure.Therefore, even if when processing local matter, really do not perform to C account Number 5 yuan of button, also can guarantee that follow-up the most enough when really withholing.

Additionally, process described transaction branch described in the embodiment of the present application, and return transaction branch state not according to described result Being only limitted to the processing mode of above two transaction mode, can also is that other forms in practice, the embodiment of the present application is not with this It is limited.

S500: first resource manager reports described transaction branch status message to task manager.

In the embodiment of the present application, after first resource manager has performed local matter, first resource manager can be to affairs pipe Reason device reports the state of Current transaction branch.When there being multiple transaction branch, first resource manager can be on task manager Report the state of each transaction branch.So task manager can get a distributed transaction several branch, and each point Prop up and whether run succeeded.Accordingly, task manager needs to first resource manager feedback transaction branch state reporting successful Message.

Further, the Global ID comprising affairs in transaction branch status message and transaction branch ID, described Global ID are reported described in With described transaction branch ID as the mark of transaction branch communication process.

Further, if client call preset service, after Secondary resource manager has performed local matter, clothes are preset Business can be called Secondary resource manager and be reported transaction branch status message to task manager.Accordingly, task manager is permissible The successful message of transaction branch state reporting is fed back to Secondary resource manager.

S600: client sends to task manager and submits distributed transaction or the message of rollback distributed transaction to.

In the embodiment of the present application, after step S500, client can to task manager send submit to distributed transaction or The message of rollback distributed transaction.Concrete, client can send the message submitting distributed transaction to task manager；Visitor Family end can send the message of rollback distributed transaction to task manager.

Further, a distributed transaction can only be finally to submit to or rollback, has the situation of multiple transaction branch affairs Under, either to submit to or rollback, each branch must be consistent, and all branches can all submit to or all rollbacks.Concrete, When all transaction branch states be all successfully time, client can to task manager send submit to distributed transaction message；Phase Answering, task manager can receive the message submitting distributed transaction to client feedback.When any one transaction branch shape State be unsuccessfully time, client can to task manager send rollback distributed transaction message, task manager can be to client End feedback receives the message of rollback distributed transaction.

Further, if client sends the message submitting distributed transaction to task manager, and at least affairs are divided State be unsuccessfully time, task manager can be to the failure of client feedback transaction branch, please the message extremely receipts of rollback transaction branch Message to the rollback distributed transaction that client sends.

In a preferred embodiment, client can send the distributed thing of submission according to transaction branch state to task manager Business or the message of rollback distributed transaction.Concrete, submit to distributed transaction or rollback to divide in client to task manager transmission Can also include before the message of cloth affairs: client can obtain the shape of current all transaction branch from first resource manager State, client determines submission distributed transaction or rollback distributed transaction according to the state of described transaction branch.Such as, when all Transaction branch state be all successfully time, client may determine that submit to distributed transaction message；As long as there being any one affairs to divide State be unsuccessfully time, client may determine that the message of rollback distributed transaction.So determine submission distribution according to transaction status Formula affairs or rollback distributed transaction can effectively prevent have transaction branch state be unsuccessfully time, have sent of user error Submit the message of distributed transaction to.

As a example by above-mentioned " A account number is to B account number remittance money " these affairs, if first transaction branch completes local matter, and Second transaction branch does not complete local matter, then arises that and has detained money in A account, but B account does not import money Mistake, as long as all, to have any one transaction branch state be unsuccessfully, and client just can send rollback distribution to task manager The message of formula affairs.

Further, task manager needs to receive submission or the message of rollback distributed transaction to client feedback.

Above-mentioned steps S100 to S600 can be as a stage, and a stage achieves the process of local matter.The application introduced below The two-stage of the communication means that embodiment provides.

S700: task manager sends the message submitting transaction branch or rollback transaction branch to receiving the to first resource manager The successful submission transaction branch of one explorer feedback or the message of success rollback transaction branch.

In the embodiment of the present application, the submission of the distributed transaction that task manager sends according to client or rollback message, to accordingly First resource manager send the submission of transaction branch or rollback message.Namely when client sends submission point to task manager During the message of cloth affairs, task manager sends the submission message of transaction branch to receiving the to corresponding first resource manager The message of the successful submission transaction branch of one explorer feedback；When client sends rollback distributed transaction to task manager Message time, task manager to corresponding first resource manager send transaction branch rollback message to receiving first resource pipe The message of the successful rollback transaction branch of reason device feedback.

Further, if client call preset service, task manager needs to send affairs to Secondary resource manager and divides Submission or rollback message to receive first resource manager feedback to receive first resource manager feedback successful submission Transaction branch or the message of success rollback transaction branch.

Further, in the case of distributed transaction is finally rollback, if in the case of multiple transaction branch, it is not necessary to return Rolling transaction branch state is failed transaction branch, as long as rollback transaction branch state is successful transaction branch.

As a example by the first transaction mode described in step S400, transaction branch is submitted to specifically include:

Owing to, under transaction mode in first, first resource manager has been carried out Current transaction, when task manager is to the first money After source manager sends the message submitting transaction branch to, first resource manager sends to task manager successfully submits to affairs to divide The message propped up, end transaction.

As a example by the first transaction mode described in step S400, in conjunction with accompanying drawing 4, rollback transaction branch specifically includes:

S711: task manager sends the message of rollback transaction branch to first resource manager.

State after S712: first resource manager performs according to the state before the execution of described transaction branch and described transaction branch is returned Rolling transaction branch state is successful transaction branch.

S713: first resource manager sends the message of successfully rollback transaction branch to task manager.

As a example by " A account number is to B account number remittance money ": assume that the state after the process of Article 1 transaction branch is successfully namely local It is successfully completed A account number to B account number remittance money；And the state after Article 2 transaction branch processes is unsuccessfully, namely this locality does not complete A account number is to B account number remittance money.Rollback transaction branch specifically includes:

Rollback Article 1 transaction branch: log-on message and corresponding branch ID according to transaction branch find corresponding daily record, root According to log recording, it is thus achieved that the remaining sum in A account after the remit money remaining sum in front A account and remittance.More than in A account before remittance After volume and remittance, the remaining sum in A account carries out respective handling to the A account balance after remittance, makes the remaining sum in A account revert to converge Remaining sum before money, i.e. completes rollback.

Do not become owing to Article 2 transaction branch does not complete A account number remaining sum in B account number remittance money, namely B account, That does not just have the needs of rollback.

Further, in step S100, to the unlatching transaction message that task manager sends, client can include that is preset a time-out Time message.Arrange described default time-out time be because when client delay machine etc. abnormal time, if having the completeest in client The affairs become, then these affairs are bound to eventually time-out, namely Current transaction bifurcation state is unsuccessfully.In order to avoid resource is grown Time takies, according to described default time-out time, task manager can judge that Current transaction is the most overtime.If overtime, affairs Manager can notify that first resource manager carries out the rollback of affairs.

As a example by the second transaction mode described in step S400, in conjunction with accompanying drawing 5, transaction branch is submitted to specifically include:

S721: task manager sends the message submitting transaction branch to first resource manager.

S722: first resource manager utilizes described reserved default resource to perform described transaction branch.

S723: first resource manager sends the message successfully submitting transaction branch to task manager.

As a example by " buying the lottery ticket of 10 yuan by C account, this lottery ticket includes 2 numerals, and each numeral is 5 yuan ", work as thing After business manager sends the message submitting transaction branch to first resource manager, first resource manager: according to transaction branch ID find corresponding daily record, according to log recording, it is thus achieved that reserved default resource.Then described reserved default money is utilized Source " 5 yuan " performs described transaction branch, namely gives 5 yuan of C account button；Then, first resource manager is to task manager Send the message successfully submitting transaction branch to.

As a example by the second transaction mode described in step S400, in conjunction with accompanying drawing 6, rollback transaction branch specifically includes:

S731: task manager sends the message of rollback transaction branch to first resource manager.

The default mark that described transaction branch state is successful transaction branch cancelled by S732: first resource manager.

S733: first resource manager sends the message of successfully rollback transaction branch to task manager.

As a example by " buying the lottery ticket of 10 yuan by C account, this lottery ticket includes 2 numerals, and each numeral is 5 yuan ", it is assumed that The state of the first transaction branch is successfully, and the state of the first transaction branch is unsuccessfully.When task manager is to first resource manager After sending the message of rollback transaction branch, namely without again C account being withholdd, then can discharge reserved resource Locking, first resource manager can cancel the default mark of the first transaction branch according to log-on message and corresponding ID so that it is Reserved resource can be operated by he in application.Owing to the state of the first transaction branch is unsuccessfully, namely first resource manager is also Do not process the first transaction branch, therefore without carrying out rollback process.Then, first resource manager sends into task manager The message of merit rollback transaction branch, end transaction.

Further, submitting distributed transaction to can only be that client is initiated, because only that client just can decide whether all branches Perform.Rollback distributed transaction can be that client is initiated, it is also possible to is that task manager is initiated, because as visitor Family end is delayed machine or do not complete for a long time affairs and submit to, and transaction time exceedes default time-out time, and task manager is permissible The corresponding explorer of proactive notification carries out rollback to branch, to avoid resource to be taken for a long time.

Further, multiple explorer can be disposed due to client, it is assumed that explorer place machine is delayed machine, affairs Manager can find its another explorer alternative to complete transaction branch submit to according to the log-on message of explorer Or rollback, do not interfere with global transaction.

Further, multiple task manager can be included due to a distributed transaction system, it is assumed that task manager is delayed machine, Can substitute for it with other task managers of group and complete new affairs.

Further, after first resource manager completes to submit transaction branch or rollback transaction branch to, first resource manager needs To report to task manager and successfully to submit transaction branch or the message of success rollback transaction branch, end transaction to.

Further, if task manager is sending submission transaction branch or rollback transaction branch to first resource manager After message, in Preset Time, do not receive successful submission transaction branch or the success rollback affairs of first resource manager feedback The message of branch, task manager may proceed to send disappearing of submission transaction branch or rollback transaction branch to first resource manager Cease to successful submission transaction branch or the message of success rollback transaction branch receiving first resource manager feedback.

As can be seen here, the technical scheme of the embodiment of the present application is after a phase transactions is opened, and explorer is noted to task manager Volume transaction branch, and transaction branch has been carried out the process of local matter, it can be ensured that the state of affairs.Divide when there being multiple affairs Zhi Shi, need not mutually etc. between each transaction branch.Namely explorer without etc. after all of transaction branch is ready to, The carrying out acted in agreement reports transaction branch state.The complete transaction branch of resource manager processes can report this transaction branch State, and after having reported transaction status, it is possible to release resource, efficiently solve the obstructing problem of existing communication method. And by calling preset service, the explorer making preset service dispose can participate in distributed transaction, and application scenarios is wider General.Compared with prior art, make communication process obstruction simple, efficient, non-, and various complex distributions formula transactional applications can be met Business scenario.

Consider that first resource manager is main step, in conjunction with accompanying drawing 7, the enforcement of the application a kind of distributed transaction communication means Example, specifically includes:

S810: receive the process transaction message that client sends.

S820: send registration transactions branch message to task manager.

S830: process described transaction branch, and return transaction branch state according to result.

S840: report described transaction branch status message to task manager.

S850: receive submission transaction branch or the message of rollback transaction branch that task manager sends, and send out to task manager Send and successfully submit transaction branch or the message of success rollback transaction branch to.

As can be seen here, in the technical scheme of the embodiment of the present application, explorer is to task manager registration transactions branch, and to thing Business branch has carried out the process of local matter, it can be ensured that the state of affairs.When there being multiple transaction branch, each transaction branch Between need not mutually etc..Namely explorer without etc. after all of transaction branch is ready to, on the carrying out acted in agreement Report transaction branch state.The complete transaction branch of resource manager processes can report the state of this transaction branch, and reports After transaction status, it is possible to release resource, efficiently solve the obstructing problem of existing communication method.Compared with prior art, Make communication process obstruction simple, efficient, non-, and various complex distributions formula transactional applications business scenario can be met.

Consider that client is main step, in conjunction with accompanying drawing 8, the embodiment of the application a kind of distributed transaction communication means, specifically Including:

S910: send to task manager and open transaction message.

S920: process transaction message to first resource manager transmission.

S930: obtain transaction branch state.

Here transaction branch state includes the result whether transaction branch is successfully processed.

S940: determine submission distributed transaction or rollback distributed transaction according to described transaction branch state.

S950: send to task manager and submit distributed transaction or the message of rollback distributed transaction to.

As can be seen here, the technical scheme of the embodiment of the present application is processing after transaction message to first resource manager transmission, resource Manager is to task manager registration transactions branch, and transaction branch has carried out the process of local matter, and such client is permissible Obtain transaction branch state accurately.And can effectively determine submission distributed transaction or rollback divides according to transaction branch state Cloth affairs.Compared with prior art, make communication process simple, efficient, and various complex distributions formula transactional applications industry can be met Business scene.

Consider that task manager is main step, in conjunction with accompanying drawing 9, the embodiment of the application a kind of distributed transaction communication means, Specifically include:

S1100: receive the unlatching transaction message that client sends.

S1200: receive the registration transactions branch message that first resource manager sends.

S1300: receive the described transaction branch status message that first resource manager sends.
