Specific embodiment

The technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.

Embodiment one

The embodiment of the present invention provides a kind of task processing method, and the method can be applied to server side, as shown in Figure 1, The method specifically includes that

Step 101: n-th processing node from message channel obtain the n-th task handle message, and according to n-th task at It manages message and executes the n-th predetermined operation, feedback message is sent to the message channel according to the implementing result of the n-th predetermined operation.

Wherein, the n is the positive integer less than N；The N is the total number of the processing node of a certain task requests of response.

Wherein, the n-th task processing message package contains the n-th processing node and holds needed for a certain task requests to respond The capable corresponding parameter of operation and the execution operation.

Here, the required operation executed refers to that the n-th processing node executes for a certain task requests of response are required The step of.The parameter refers to that the n-th processing node is parameter used the step of execution needed for a certain task requests of response；Its In, the parameter may include the processing result of the upper processing node of the n-th processing node.

For example, the content executed needed for described includes: the n-th predetermined operation；N-th predetermined operation is to respond the task to ask The response operation asked.

Wherein, n-th predetermined operation is the pre- stator operation of one or more that the n-th processing node executes.

That is, the n-th processing node is supported to execute at least one pre- stator operation, when the n-th processing node When executing different pre- stator operations, it is able to achieve different functions.

For example, 2 processing nodes are shared, each processing node can execute multiple pre- stator operations.1st processing section Point can support two pre- stator operations of S1, S2；Wherein, the pre- stator operation of S1 is to obtain log-on message, and the pre- stator operation of S2 is root It determines whether to enter certain account system according to authenticating result；2nd processing node can support two pre- stator operations of S3, S4； Wherein, the pre- stator operation of S3 is to authenticate to log-on message, returns to authenticating result；The pre- stator operation of S4 be establish account with it is close The corresponding relationship of code.So, when receiving the task requests of a login account, the 1st processing node executes the predetermined behaviour of S1 Make, i.e. acquisition log-on message；2nd processing node executes S3 predetermined operation, i.e., authenticates to the log-on message；2nd processing Node executes S3 predetermined operation, i.e., authenticates to the log-on message, returns to authenticating result；It is pre- that 3rd processing node executes S2 Fixed operation determines whether to enter certain account system according to authenticating result.So far, at by the 1st processing node and the 2nd It manages node and executes corresponding pre- stator operation, the task requests can be completed.

In the present embodiment, the message channel is used to store the task processing message of each processing node, is also used to receive The feedback message of each processing node.For example, the message channel includes the various transmission channels such as message queue, data/address bus. Preferably, the message channel includes message queue, and the message queue is the appearance that message is saved in the transmission process of message Device.

In an optional embodiment, the message channel includes multiple sub- message channels, each processing node corresponding one A sub- message channel, each processing node can be obtained from corresponding sub- message channel task processing message, and to Its corresponding sub- message channel sends feedback message；The multiple sub- message channel is connected with a total message channel, institute It states total message channel and takes out feedback message from each sub- message channel, and distributed simultaneously based on feedback message to each sub- message channel Transmission task handles message.In this way, identifying and obtaining convenient for each processing node since each sub- message channel is independent from each other Corresponding task is taken to handle message.

Step 102: when n-th predetermined operation execution is correct, the (n+1)th processing node is obtained from the message channel Message is handled based on the (n+1)th task that the feedback message is formed, and message is handled according to (n+1)th task and executes (n+1)th Predetermined operation.

Wherein, (n+1)th predetermined operation is the pre- stator operation of one or more that the (n+1)th processing node executes.

Wherein, the (n+1)th processing node is next processing node of the n-th processing node；N-th predetermined operation It is to respond the response operation of same task requests with (n+1)th predetermined operation.

For example, a certain task requests need A processing node, B processing node, C processing node collaboration to complete.Each It is different to handle function achieved by node, for example, tri- kinds of predetermined operations of A1, A2, A3 can be performed in A processing node, different is pre- It is fixed to operate brought response results difference；B, which handles node, can be performed tetra- kinds of predetermined operations of B1, B2, B3, B4, and different is predetermined Response results brought by operating are different；C, which handles node, can be performed tri- kinds of predetermined operations of C1, C2, C3, different predetermined operation institutes Bring response results are different.

As shown in Fig. 2, A processing node needs to be implemented A3 predetermined operation, and B handles node and needs when executing a certain task requests B2 predetermined operation is executed, C processing node needs to be implemented C1 predetermined operation；And execution sequence is A3 predetermined operation, the predetermined behaviour of B2 Make, C1 predetermined operation.Therefore, A handles node and obtains A task processing message from message channel, when A processing node execution A3 is pre- Surely the implementing result operated is when executing correct, and B processing node obtains B task processing message from message channel, when B processing saves The implementing result that point executes B2 predetermined operation is when executing correct, and C processing node obtains the processing of C task from message channel and disappears Breath, when the implementing result that C processing node executes C1 predetermined operation is to execute correct, the task requests execute completion.

Again for example, task requests 1 need to use A shown in Fig. 2 processing node, B processing node, C processing node, and It needs A processing node to execute A3 predetermined operation, B processing node is needed to execute B2 predetermined operation, need C processing node to execute C1 pre- Fixed operation；Task requests 4 need to use A shown in Fig. 2 and handle node, B processing node, and it is pre- to need A processing node to execute A2 Fixed operation needs B processing node to execute B1 predetermined operation；If execute task requests 1, A handles node and executes A3 predetermined operation It executes correctly, B processing node execution B2 predetermined operation execution is correct, and the node of C processing at this time is in upgrade status, task requests 1 Temporarily it is unable to complete, and at this point, can continue after a period of time at C due to distributing task processing message by message channel It manages node or sends task to spare C processing node and handle message.While executing task 1, by message channel at A It manages node and distributes the task processing message for executing A2 predetermined operation, after A processing node distribution execution A2 predetermined operation is correct, to B handles the task processing message that node distribution executes B1 predetermined operation.Obviously, the execution of task requests 1, which is not constituted, appoints execution The influence of business request 2.

In an optional embodiment, the implementing result according to the n-th predetermined operation sends anti-to the message channel After presenting message, the method also includes:

Control node judges whether the implementing result of n-th predetermined operation executes correctly based on the feedback message, In, the feedback message includes the implementing result of the n-th predetermined operation；

When n-th predetermined operation execution is correct, the task based on the task requests handles inventory to the message Channel is sent the (n+1)th task formed based on the feedback message and handles message.

Wherein, the feedback message includes the implementing result of n-th predetermined operation.

Wherein, the (n+1)th task processing message includes the (n+1)th predetermined operation executed by the (n+1)th processing node, The (n+1)th task processing message is that the control node task based access control processing inventory determines.

Wherein, the task processing inventory includes the N number of processing node for executing the task requests and N number of institute That states the predetermined operation that processing node executes executes sequence.

As shown in figure 3, formulating task processing according to the task requests by control node when system receives task requests Inventory, and inventory is handled based on the task and handles message to each processing node distribution task, receive what each processing node returned Feedback message；

That is, judging whether the implementing result of the n-th processing node the n-th predetermined operation of execution executes by control node Correctly, the n-th processing node is without judging its implementing result.N-th processing node only needs to disappear from the processing of the n-th task The predetermined operation that it to be executed and the execution parameter that it to be returned are obtained in breath, without be concerned about next node by who Lai Operation.

In another optional embodiment, the method also includes:

The n-th processing node judges whether n-th predetermined operation executes correctly；

When n-th predetermined operation executes it is correct when, then according to the implementing result of the n-th predetermined operation to the message channel Feed back first kind message；Wherein, the first kind message includes the implementing result of the n-th processing node, the n-th processing section Point handles the node identification for the (n+1)th processing node that inventory determines according to task and the task handles inventory；Wherein, institute Stating task processing inventory includes executing each processing node identification of node involved in the task requests and described each Handle execution sequence and the predetermined operation between node.

As shown in figure 4, formulating task processing according to the task requests by control node when system receives task requests Task processing inventory is sent to first processing node in task processing inventory by message channel by inventory, later, The first kind message that first handles node feeding back is handled into message directly as the task of next processing node, by described Message channel is sent to first specified next processing node of processing node, and so on, the control node is not necessarily to root Determine that the task of next processing node handles message according to the feedback information of each processing node.

That is, by n-th processing node come judge the n-th processing node execute the n-th predetermined operation implementing result whether It executes correctly, the n-th processing node handles inventory according to task and determines that whom next processing node is, and specified by the first kind Message is sent to its identified (n+1)th processing node, the throwing that the control node only need to be specified according to the n-th processing node Object is passed by the first kind message after encapsulation, i.e., by task processing message by being sent to the (n+1)th processing node in message channel.

Step 103: when n-th predetermined operation executes mistake, abnormality processing node is obtained from the message channel Message is handled based on the abnormal task that the feedback message is formed, and message is handled according to the abnormal task and executes abnormality processing Operation.

In this way, abnormal task requests are executed to handle by a special processing node, it can be abnormal to processing in time Task requests handled.Abnormal task requests are executed to handle by a special processing node, can be found in time Abnormal problem is executed, timely reply can be also made according to the problem.For example, the place that the abnormality processing node will go wrong Task processing message corresponding to reason node is sent to another spare task that is able to carry out by message channel and handles message Processing node, in this way, when this it is spare processing node implementing result it is correct when, additionally it is possible to continue to execute the task requests, should Task requests will not stop due to mistake occurs in intermediate a certain link.

For example, task requests 1, task requests 2 are required to use A processing node shown in Fig. 2, B processing node, C Handle node；And be required to B processing node and execute B2 predetermined operation, if execute task requests 1, it is pre- that B handles node execution B2 There is exception in fixed operation, if the data that clean-up task request 1 generates not in time, influence the implementation progress of task requests 2.And it adopts Message is handled with abnormality processing node special disposal abnormal task, as carrying out in time to data caused by task requests 1 Processing, will not cause big influence to the execution of task requests 2.

Again for example, task requests 1 need to use A shown in Fig. 2 processing node, B processing node, C processing node, and It needs A processing node to execute A3 predetermined operation, B processing node is needed to execute B2 predetermined operation, need C processing node to execute C1 pre- Fixed operation；If B, which handles node and executes B2 predetermined operation, to be occurred abnormal, then abnormality processing node can will when executing task requests 1 Notification message channel sends task to spare B ' processing node and handles message, and notice B ' processing node executes B2 predetermined operation, In this way, C processing node can continue to execute the predetermined behaviour of C1 when the implementing result that B ' processing node executes B2 predetermined operation is correct Make, in this way, will not cause task requests 1 that can not continue to execute because B handles the implementing result mistake of node.

Here, the step 102 and the step 103 are coordination.I.e. after step 101, if it is predetermined to work as described n-th When operation executes correct, step 102 is executed；If executing step 103 when n-th predetermined operation executes mistake.

When n-th predetermined operation executes mistake, abnormality processing node in control node notice system, by exception Reason node task based access control, which is handled inventory and sends the abnormal task formed based on the feedback message to the message channel and handle, to disappear Breath；Wherein, the task processing inventory includes the N number of processing node for executing the task requests and N number of processing The predetermined operation that node executes executes sequence.

In another optional embodiment, the method also includes:

When n-th predetermined operation, which executes, occurs abnormal, then according to the implementing result of the n-th predetermined operation to the message Feed back the second class message in channel；Wherein, the second class message includes the implementing result of the n-th processing node, at described n-th Manage the abnormality processing node and task processing inventory that node determines；

The abnormality processing node determined from the n-th processing node is based on the task and handles inventory to the message channel It sends the abnormal task formed based on the second class message and handles message.

Here, the abnormality processing node in system can be multiple.

When continuing to execute a certain task requests, A processing node needs to be implemented A3 predetermined operation, and B processing node needs are held Row B2 predetermined operation, C processing node need to be implemented C1 predetermined operation；And execution sequence is A3 predetermined operation, B2 predetermined operation, C1 It is illustrated for predetermined operation.As shown in figure 5, A processing node obtains A task processing message from message channel, when A processing The implementing result that node executes A3 predetermined operation is when executing correct, and B processing node obtains the processing of B task from message channel and disappears Breath, when the implementing result that B processing node executes B2 predetermined operation is to execute correct, C processing node obtains C from message channel Task handles message, and when the implementing result that C processing node executes C1 predetermined operation is to execute mistake, abnormality processing node is from institute It states and obtains the abnormal task processing message that the feedback message based on C processing node is formed in message channel, and according to the exception Task handles message and executes abnormality processing operation.

In one embodiment, the abnormal task formed based on the feedback message handles message, comprising:

Determine each processing node for needing to be implemented abnormality processing operation and the sequence for executing abnormality processing.

For example, the abnormality processing operation, comprising: generated data will be deleted during executing the task requests It removes.

In this way, when reusing same memory space, convenient for when executing other task requests or re-executing described When task requests, generated data relevant to the task requests interfere currently performed task requests before.

For another example, the abnormality processing operation, comprising: execute rolling back action.

Here, the rolling back action refers to the behavior that program or data are restored to last correct status.

When continuing to execute a certain task requests, A processing node needs to be implemented A3 predetermined operation, and B processing node needs are held Row B2 predetermined operation, C processing node need to be implemented C1 predetermined operation；And execution sequence is A3 predetermined operation, B2 predetermined operation, C1 It is illustrated for predetermined operation.When the implementing result that A processing node executes A3 predetermined operation is to execute correctly, B handles node The implementing result for executing B2 predetermined operation is to execute correctly, and the implementing result that C processing node executes C1 predetermined operation is to execute mistake It mistakes, abnormality processing node is from the abnormal task for obtaining the feedback message formation based on C processing node in the message channel Message is managed, and message is handled according to the abnormal task and executes rolling back action operation, abnormality processing node is from the message channel The middle abnormal task processing message for obtaining the feedback message based on C processing node and being formed, and handled and disappeared according to the abnormal task Breath executes abnormality processing operation, wherein and the abnormal task processing message includes: that C processing node needs to be implemented E1 predetermined operation, B processing node needs to be implemented E1 predetermined operation, and A processing node needs to be implemented E1 predetermined operation；And execution sequence is C processing section Point, B processing node, A handle node, wherein the E1 predetermined operation indicates rolling back action；Make a reservation for when C processing node executes E1 When end of operation, B processing node executes E1 predetermined operation and finishes, when A processing node execution E1 predetermined operation finishes, for this The rolling back action of business request is completed.

In an optional embodiment, the sequence for executing abnormality processing are as follows: different currently to execute task requests appearance Normal processing node be starting point, according to each processing node for having executed the task requests execution sequence inverted order mode into Row sequence.

For example, as shown in fig. 6, abnormality processing node is obtained from the message channel based on the anti-of C processing node It presents the abnormal task that message is formed and handles message, and message is handled according to the abnormal task and executes abnormality processing operation, wherein The abnormal task processing message includes: that C processing node needs to be implemented E1 predetermined operation, and it is predetermined that B processing node needs to be implemented E1 Operation, A processing node need to be implemented E1 predetermined operation；And execution sequence is C processing node, B processing node, A processing node.Such as Shown in Fig. 6, C processing node obtains C abnormal task processing message from message channel, when C processing node executes E1 predetermined operation When finishing, B processing node obtains B abnormal task processing message from message channel, when B processing node execution E1 predetermined operation is complete Bi Shi, A processing node obtain A abnormal task processing message from message channel, finish when A processing node executes E1 predetermined operation When, completion is operated for the abnormality processing of the task requests.

In above scheme, optionally, the method also includes:
