Step 201, task manager receives business information, and the entity of mission bit stream business information included is added in task pool, calls management module to process the entity in task pool, and calls the management module result with the entity in acquisition process task pool。

In the present embodiment, multithreading task processing method runs on electronic equipment thereon (such as the server shown in Fig. 1), it can be utilized by wired connection mode or radio connection to submit to the terminal of business information to receive business information from user, wherein, business information can include the entity of multiple mission bit stream。Such as, reimbursement business information potentially include frozen capital pond mission bit stream, deduct fees mission bit stream and reimbursement mission bit stream etc.。

In above-mentioned electronic equipment, it is possible to running and have task manager, receive business information by task manager, the entity of mission bit stream business information included is added in task pool。

The entity of mission bit stream here, is generally of certain feature or attribute, thus can make a distinction with the entity of other mission bit stream in data handling。The entity of mission bit stream can include token token, for verifying the identity information of entity。Additionally, the entity of mission bit stream can also include but not limited to: lock mark and/or task processes function。Wherein, lock mark and may indicate that the lock that the entity of mission bit stream uses in processing procedure；It can be homophony function that task processes function, to call the entity of called function process mission bit stream。

Here task pool, the entity of all pending mission bit streams of buffer memory, is the container of task, it is possible to share task at cross-thread, and all read-writes for task pool are all thread-safes。

Task manager is after the entity of mission bit stream is added in task pool, it is possible to call management module to process the entity in task pool, recalls the management module result with the entity in acquisition process task pool afterwards。

In some optional implementations of the present embodiment, task manager can also carry out following one or more process: determines distributed lock in response to receiving user's selection, and is added into by distributed lock in distributed lock pond；Receive to add and perform module instruction, add new execution module to performing module pond according to adding execution module instruction；And receive interpolation monitoring module instruction, add new monitoring module extremely monitoring module pond etc. according to adding monitoring module instruction。

Step 202, management module calls execution module to process the entity in task pool, calls the result monitoring module to obtain the entity performed in resume module task pool。

In the present embodiment, management module and perform that module is equally possible runs in above-mentioned electronic equipment (such as the server shown in Fig. 1)。In response to the calling management module of task manager in step 201, management module can call execution module to process the entity in task pool, it is also possible to calls the result monitoring module to obtain the entity performed in resume module task pool。

In some optional implementations of the present embodiment, receive to add corresponding to above-mentioned task manager and perform module instruction, the new execution module of module instruction interpolation is performed to performing module pond according to adding, management module is when calling execution module to process the entity in task pool, it is possible to perform module to process the entity in task pool from performing to call module pond。

In some optional implementations of the present embodiment, receive to add corresponding to above-mentioned task manager and monitor module instruction, the new monitoring module of module instruction interpolation is monitored to monitoring module pond according to adding, management module is when calling monitoring module to obtain the result performing resume module entity, it is possible to call, from monitoring, the result monitoring module to obtain the entity performing resume module acquisition module pond。

Step 203, performs module and obtains entity from task pool, and the task of the entity calling thread, lock and acquisition processes function, and the entity obtained is processed, and the result notice processed is monitored module。

In the present embodiment, perform module from task pool, obtain the thread called after entity, be the minimum unit of program execution stream。The thread of one standard is by thread identity number, current instruction pointer, set of registers and storehouse composition。It addition, thread is an entity in process, it is the ultimate unit being independently scheduled and assigning, can share, with other thread belonging to a process together, whole resources that process has。Single program is run multiple thread simultaneously and completes different work, be called multithreading。Can concurrently perform between multiple threads。Due to the mutual restriction between thread, cause thread to be in operation and present discontinuity。Thread also has ready, obstruction and runs three kinds of basic status。Ready state refers to that thread possesses all conditions of operation, can run in logic, is waiting datatron；Running status refers to that thread occupies datatron and is currently running；Blocked state refers to that thread is waiting an event (such as certain semaphore), can not perform in logic。

In order to optimize the using method of thread in task processes, it is possible to pre-set thread pool, add task to queue, then after creating thread, automatically start these tasks。The thread of thread pool is all background thread。Thread pool can the thread of all execution tasks of buffer memory, and be responsible for termination and the management thread information of whole business。Each thread uses the storehouse size of acquiescence, runs with the priority of acquiescence, and is in multiple thread units。If certain thread is idle (as waited certain event) in Managed Code, then another worker thread of insertion is made all processors keep busy by thread pool。If the thread of all thread pools all remains busy, but comprise the work of hang-up in queue, then thread pool will create another worker thread over time, but the number of thread exceedes maximum never。The thread exceeding maximum can be queued up, but to wait until that other threads just start after completing。

Perform module from task pool, obtain the lock called after entity, it is possible to determine according to the locking of the entity obtained mark。In order to optimize the use of lock in task processes, the lock pond object with all distributed locks of buffer memory can be pre-set, performance element is after the locking mark according to the entity obtained determines lock, call in lock pond the object with the phase-locked corresponding lock determined task is locked, to improve the safety of task。What this distributed task scheduling performed adds lock technology (such as, distributed by distributed cache systems MemCache realization adds lock technology), can adopt for different tasks and different add lock technology, can ensure that the concordance of shared resource, and make technological development personnel self-defined to lock to realize, the maximized motility improving scheme and autgmentability, also meet the opening and closing principle of design。

The task of performing the entity that module obtains the acquisition called after entity from task pool processes function, it is possible to for homophony function, execution module can call called function to process the entity of the mission bit stream obtained by calling this homophony function。

Performing module and obtains entity from above-mentioned task pool, the task of the entity calling above-mentioned thread, lock and above-mentioned acquisition afterwards processes function, and the entity obtained is processed, the result notice monitoring module that can process afterwards。Notice monitors the mode of module can adopt advice method of the prior art, for instance, it is possible to the mode that notified by event or monitor module by audiomonitor notice。

In some optional implementations of the present embodiment, distributed lock is determined in response to receiving user's selection corresponding to above-mentioned task manager, and distributed lock is added in distributed lock pond, perform module when calling lock, it is possible to the locking of entity calling acquisition from distributed lock pond identifies indicated lock。

In this implementation, distributed lock is to control synchronization of access between distributed system to share a kind of mode of resource。In a distributed system, it is often necessary to coordinate the action of each system。If have shared one or one group of resource between different systems or the different main frames of same system, then when accessing these resources, generally requiring mutual exclusion preventing and interfering with each other ensureing concordance, in this case, just needing to use distributed lock。

Step 204, monitors module according to the result record pass flag processed or fail flag, and pass flag or fail flag is sent to management module。

In the present embodiment, monitor module after obtaining the result processed, if the result processed is successfully, then can record pass flag, and the pass flag of record is sent to management module；If the result processed is unsuccessfully, then records fail flag, and the fail flag of record is sent to management module。

In some optional implementations of the present embodiment, the entity of above-mentioned mission bit stream can also include number of retries, monitoring module can according to the result record fail flag processed, and when the fail flag of record is sent to management module, it is unsuccessfully in response to the result processed, number of retries according to the entity obtained, notice performs module and retries the entity processing acquisition, when the number of times retrying process reach number of retries but process result be still unsuccessfully time, record fail flag, and fail flag is sent to management module。

In some optional implementations of the present embodiment, management module can after receiving pass flag or fail flag, it is possible to the result processed is carried out following one or more process: is stored in data base, write daily record and notice Third party system etc.。

Refer to the schematic diagram that Fig. 3, Fig. 3 illustrate a concrete implementation scene of multithreading task processing method according to the embodiment of the present application。

As shown in Figure 3, first task manager 311 receives the business information that user 301 submits to, the entity of mission bit stream business information included is added into task pool 350, and call leader 321 and process the entity in task pool 350, now the management module in above-described embodiment exists with the form of leader 321；Leader 321 calls the executor 331 in executor pond 330 to process the entity in task pool afterwards, call observer 341 and process the result of the entity in task pool 350 to obtain executor 331, now the execution module in above-described embodiment exists with the form of executor 331, monitors module and exists with the form of observer 341；Executor 331 obtains the entity of task from task pool 350 afterwards, the task of the entity calling the lock in the thread in thread pool 360, distributed lock pond 370 and acquisition processes function, the entity obtained is processed, and from observer pond 340, call observer 341, the result of process is notified observer 341；The result of process is fed back to leader 321 by observer 341 afterwards；Last task manager 311 calls the result that leader 321 acquisition processes。In this course, task manager 311 can also carry out with the next item down or multithread operation: can select in response to receiving user and determine distributed lock, and is added into by distributed lock in distributed lock pond 370；Can receiving the instruction adding executor, new executor 331 to executor pond 330 is added in the instruction according to adding executor；And the instruction adding observer can be received, new observer 341 to observer pond 340 is added in the instruction according to adding observer。

The multithreading task processing method that the above embodiments of the present application provide, the entity of multiple mission bit streams is performed by multiple thread parallels, even if the mission bit stream that business information includes is more, without because of the too much situation of step or each Step Time is long and the growth that causes the execution cycle of whole business to become times several levels, the time processing single business is shorter, thus improve the efficiency of process business。

The indicative flowchart according to the method presetting process time-triggered protocol mission bit stream according to the embodiment of the present application is illustrated with further reference to Fig. 4, Fig. 4。

On the basis of the embodiment described in above-mentioned Fig. 2, as shown in Figure 4, the method 400 according to default process time-triggered protocol mission bit stream may include that

Step 401: task manager receives business information, is added in the entity of the mission bit stream that business information includes the default process time, and is added in task pool by the entity adding the default process time。

In the present embodiment, step 401 can be that in step 201, task manager receives business information, and the entity of the mission bit stream that can include in business information is added into an optional implementation in task pool。

Wherein, the default process time of mission bit stream may come from the setting processing the time to each task and/or whole business that task manager receives。If this setting be only to whole business process the time setting, then can by task manager according to preset process the time allocation rule setting each task the process time。

Step 402: management module is in response to the result not receiving process within the default process time, send command for stopping and added the entity of default process time to execution module with termination, and the entity adding the default process time is added in task pool again。

In the present embodiment, step 402 can be that in step 202, management module calls execution module to process an optional implementation of the entity in task pool。

Wherein, in response to above-mentioned task manager reception is the setting processing the time to each task, so management module can exceed process time of setting in response to the time processing individual task, will this task of interrupt processing automatically, and do not affect the execution to other task of other threads。

In response to above-mentioned task manager reception is the setting processing the time to whole business, so task manager can set the process time of each task according to the default allocation rule processing the time, management module can exceed process time of setting in response to the time processing individual task, this task of automatic interrupt processing, and do not affect the execution to other task of other threads；Management module may also respond to the time processing whole business beyond the process time set, and stops still off-duty task, interrupts being currently running of task simultaneously。

In response to above-mentioned task manager reception is the process time that each task and whole business are set respectively, so management module exceedes the process time of setting in response to the time processing individual task, will this task of interrupt processing automatically, and do not affect the execution to other task of other threads；Management module may also respond to the time processing whole business beyond the process time set, and stops still off-duty task, interrupts being currently running of task simultaneously。

Figure 4, it is seen that compared with the embodiment that Fig. 2 is corresponding, the multithreading task processing method in the present embodiment highlights the step of the default process time-triggered protocol mission bit stream according to mission bit stream。Thus, the scheme that the present embodiment describes can pass through mission bit stream is processed the setting of time, the process time of individual task and whole business is controlled, thus well ensureing the ageing of whole business。

An indicative flowchart of the method for the entity corresponding with fail flag according to transaction journal rollback according to the embodiment of the present application is illustrated with further reference to Fig. 5, Fig. 5。

On the basis of the embodiment described in above-mentioned Fig. 2 or Fig. 4, as it is shown in figure 5, the method 500 according to the transaction journal rollback entity corresponding with fail flag may include that

Step 501: task manager may also respond to the entity of mission bit stream and meets default transaction conditions, starts the affairs of the entity of mission bit stream。

In the present embodiment, the transaction conditions preset is the required condition met of the entity needing to start affairs set in advance, and when the entity of mission bit stream meets default transaction conditions, task manager starts the affairs of the entity of this mission bit stream。Such as, the transaction conditions preset is when the entity of mission bit stream is for the task of deducting fees or reimbursement task, starts the affairs of the entity of mission bit stream。Affairs are to access and be likely to a program execution unit of various data item in more new database。Affairs generally by Advanced Database manipulation language or programming language (such as SQL, C++ or Java) caused by the execution of user program write, and start (begintransaction) by shape such as affairs and affairs terminate (endtransaction) statement (or function call) and define。Affairs are started (begintransaction) by affairs and affairs terminate all operations of execution between (endtransaction) and form。Such as: in relational database, affairs can be a SQL statement, one group of SQL statement or whole program。The execution process of affairs generates transaction journal。

Affairs have 4 attributes: atomicity, concordance, isolation and persistency, are recover the ultimate unit with con current control。Wherein, atomicity refers to that affairs are indivisible work units, all operations that affairs include or all do, or does not do；Concordance refers to that affairs must be make data base change to another coherency state from a coherency state。Concordance and atomicity are closely-related；Isolation refers to that other concurrent affairs are isolate by the data of i.e. operation affairs within and use, can not interfere with each other between each affairs concurrently performed；Persistency, also referred to as permanent, refers to affairs once submit to, and the change of data in data base should be just permanent by it。It should not had any impact by other operations ensuing or fault。

Task manager meets default transaction conditions in response to the entity of mission bit stream, the affairs of the entity starting mission bit stream may include that task manager meets default transaction conditions in response to the entity of mission bit stream, affairs start, and the result in response to the entity processing this mission bit stream obtained from management module is that successfully affairs terminate。

Step 502: management module, in response to receiving fail flag and the entity corresponding with fail flag starts affairs in advance, is called and performed module with the rollback entity corresponding with fail flag。

In the present embodiment, management module is in response to receiving fail flag, and the entity corresponding with fail flag starts affairs in advance, owing to the affairs of the entity corresponding with fail flag fail to submit to, therefore management module can call execution module, by performing module according to the transaction journal rollback entity corresponding with fail flag。

In some optional implementations of the present embodiment, the entity of above-mentioned mission bit stream can also include rollback function；Management module call perform module with entity that rollback fail flag is corresponding time, it is possible to calls rollback function is with the rollback entity corresponding with fail flag。

In this implementation, rollback function is homophony function, and when the entity handles failure of mission bit stream, management module can call called function, with the entity corresponding with fail flag according to transaction journal rollback。

From figure 5 it can be seen that compared with the embodiment that Fig. 2 is corresponding, the multithreading task processing method in the present embodiment highlights the step of the transaction rollback of the entity according to the mission bit stream entity corresponding with fail flag。Thus, the scheme that the present embodiment describes can be passed through the entity of the mission bit stream opening affairs in advance to failure and carry out rollback, and lifting processes the success rate of mission bit stream, thus improving the success rate of whole business, it is ensured that the atomicity of whole Business Stream。
