The technical solution of the present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one
The embodiment of the present invention provides a kind of task processing method, and described method can be applicable to server side, as it is shown in figure 1, Described method specifically includes that
Step 101: n-th process node from message channel obtain n-th task process message, and according to described n-th task at Reason message performs the n-th scheduled operation, sends feedback message according to the execution result of the n-th scheduled operation to described message channel.
Wherein, described n is the positive integer less than N；Described N is the total number processing node responding a certain task requests.
Wherein, described n-th task process message includes described n-th process node for holding needed for responding a certain task requests The operation gone and the parameter performing described operation correspondence.
Here, the described required operation performed refers to that a certain task requests is required to be performed described n-th process node in order to respond Step.Described parameter refers to that the n-th process node is to respond the required parameter used in step performed of a certain task requests；Its In, described parameter can include the result of the described n-th upper process node processing node.
Such as, the described required content performed includes: the n-th scheduled operation；Described n-th scheduled operation please for responding this task The response operation asked.
Wherein, described n-th scheduled operation is the described n-th one or more pre-stator operation processing that node performs.
It is to say, described n-th process node support performs at least one pre-stator operation, when described n-th processes node When performing different pre-stator operation, different functions can be realized.
For example, having 2 and process node, each process node all can perform multiple pre-stator operation.1st processes joint Point can support two pre-stator operation of S1, S2；Wherein, the pre-stator operation of S1 is for obtaining log-on message, and the pre-stator operation of S2 is root Determine whether to enter certain account system according to authenticating result；2nd processes node and can support two pre-stator operation of S3, S4； Wherein, the pre-stator operation of S3, for authenticate log-on message, returns authenticating result；The pre-stator operation of S4 is for setting up account with close The corresponding relation of code.So, when receiving the task requests of a login account, the 1st processes node and performs the predetermined behaviour of S1 Make, i.e. obtain log-on message；2nd processes node performs S3 scheduled operation, i.e. authenticates described log-on message；2nd processes Node performs S3 scheduled operation, i.e. authenticates described log-on message, returns authenticating result；It is pre-that 3rd process node performs S2 Fixed operation, i.e. determines whether to enter certain account system according to authenticating result.So far, process at node and the 2nd by the 1st Reason node performs corresponding pre-stator operation, can complete this task requests.
In the present embodiment, described message channel processes message for storing each task of processing node, is additionally operable to receive Each processes the feedback message of node.Such as, described message channel includes the various transmission channel such as message queue, data/address bus. Preferably, described message channel includes that message queue, described message queue are the appearances preserving message in the transmitting procedure of message Device.
In an optional embodiment, described message channel includes many sub-message channels, each process node correspondence one Individual sub-message channel, each process node all can obtain from corresponding sub-message channel task process message, and to The sub-message channel of its correspondence sends feedback message；The plurality of sub-message channel is all connected with a total message channel, institute State total message channel and take out feedback message from each sub-message channel, and distribute also to each sub-message channel based on feedback message Transmission task processes message.So, it is separate due to each sub-message channel, it is simple to each process node identification and obtaining Take corresponding task and process message.
Step 102: when described n-th scheduled operation performs correct, (n+1)th processes node obtains from described message channel The (n+1)th task formed based on described feedback message processes message, and processes message execution (n+1)th according to described (n+1)th task Scheduled operation.
Wherein, described (n+1)th scheduled operation is the described (n+1)th one or more pre-stator operation processing that node performs.
Wherein, described (n+1)th next process node that node is described n-th process node is processed；Described n-th scheduled operation It is the response operation responding same task requests with described (n+1)th scheduled operation.
For example, a certain task requests needs A to process node, B processes node, C processes node and worked in coordination with.Each Processing the function achieved by node different, such as, A processes node can perform tri-kinds of scheduled operations of A1, A2, A3, and different is pre- Calmly operate the response results brought different；B processes node can perform tetra-kinds of scheduled operations of B1, B2, B3, B4, and different is predetermined The response results that operation is brought is different；C processes node can perform tri-kinds of scheduled operations of C1, C2, C3, different scheduled operation institutes The response results brought is different.
During as in figure 2 it is shown, perform a certain task requests, A processes node to be needed to perform A3 scheduled operation, and B processes node and needs B2 scheduled operation to be performed, C processes node to be needed to perform C1 scheduled operation；And execution sequence is A3 scheduled operation, the predetermined behaviour of B2 Work, C1 scheduled operation.Therefore, A processes node and obtains A task process message from message channel, when A process node execution A3 is pre- When the execution result of fixed operation is for performing correct, B process node obtains B task from message channel and processes message, when B processes joint Point perform B2 scheduled operation execution result for perform correct time, C process node obtains from message channel C task process disappear Breath, when C processes the execution result of node execution C1 scheduled operation for performing correct, described task requests has performed.
The most for example, task requests 1 needs to use the A process node shown in Fig. 2, B processes node, C processes node, and Need A to process node and perform A3 scheduled operation, need B to process node and perform B2 scheduled operation, need C process node to perform C1 pre- Fixed operation；Task requests 4 needs to use the A process node shown in Fig. 2, B processes node, and it is pre-to need A to process node execution A2 Fixed operation, needs B to process node and performs B1 scheduled operation；If perform task requests 1, A processes node and performs A3 scheduled operation Performing correct, B processes node execution B2 scheduled operation and performs correct, and now C processes node and is in upgrade status, task requests 1 Temporarily cannot complete, and now, owing to processing message by message channel distribution task, can continue after a period of time at C Manage node or process node transmission task process message to standby C.While performing task 1, by message channel at A Reason node distributes the task process message performing A2 scheduled operation, after A process node distribution execution A2 scheduled operation is correct, to B processes node distribution and performs the task process message of B1 scheduled operation.Obviously, the execution of task requests 1 is not constituted performing to appoint The impact of business request 2.
In an optional embodiment, the described execution result according to the n-th scheduled operation sends anti-to described message channel After feedback message, described method also includes:
Control node and judge whether the execution result of described n-th scheduled operation performs correctly based on described feedback message, its In, described feedback message includes the execution result of the n-th scheduled operation；
When described n-th scheduled operation performs correct, task based on described task requests processes inventory to described message Passage sends the (n+1)th task formed based on described feedback message and processes message.
Wherein, described feedback message includes the execution result of described n-th scheduled operation.
Wherein, described (n+1)th task processes message and includes being processed, by described (n+1)th, the (n+1)th scheduled operation that node performs, It is that described control node task based access control process inventory determines that described (n+1)th task processes message.
Wherein, described task processes the N number of described process node that inventory includes performing described task requests, and N number of institute State the execution sequence processing the scheduled operation that node performs.
During as it is shown on figure 3, system receives task requests, formulated task process by controlling node according to described task requests Inventory, and process message based on described task process inventory to each process node distribution task, receive what each process node returned Feedback message；
It is to say, judged that the n-th process node performs the execution result of the n-th scheduled operation and whether performs by controlling node Correctly, described n-th node is processed without its execution result is judged.N-th processes node only needs to process from the n-th task to disappear Breath obtains its scheduled operation to be performed and its execution parameter to be returned, it is not necessary to be concerned about that whom next node come by Operation.
In another optional embodiment, described method also includes:
Described n-th processes node judges whether described n-th scheduled operation performs correctly；
When described n-th scheduled operation performs correct, then according to the execution result of the n-th scheduled operation to described message channel Feedback first kind message；Wherein, described first kind message includes that described n-th processes the execution result of node, described n-th process joint Point processes node identification and the described task process inventory of the (n+1)th process node that inventory determines according to task；Wherein, institute Task of stating process that inventory includes performing involved by described task requests each process the node identification of node, and described each Process the execution sequence between node and scheduled operation.
As shown in Figure 4, when system receives task requests, formulated task process by controlling node according to described task requests Inventory, by described task process inventory by first process node in message channel transmission to task process inventory, afterwards, The task that the first kind message processing node feeding back by first processes node directly as the next one processes message, by described Message channel sends the next process node specified to first process node, and by that analogy, described control node is without root Determine that the next task of processing node processes message according to the feedback information of each process node.
It is to say, processed node by n-th to judge whether the n-th process node performs the execution result of the n-th scheduled operation Performing correct, according to task process inventory, described n-th processes node determines that the next one processes whom node is, and specify the first kind Message sends to the (n+1)th process node determined by it, and described control node only need to process, according to described n-th, the throwing that node be specified Pass the first kind message after object will encapsulate, task will process message by message channel sending to the (n+1)th process node.
Step 103: when described n-th scheduled operation performs mistake, abnormality processing node obtains from described message channel The abnormal task formed based on described feedback message processes message, and processes message execution abnormality processing according to described abnormal task Operation.
So, process, by a special node that processes, the task requests that execution is abnormal, it is possible to abnormal to processing in time Task requests process.The task requests that execution is abnormal is processed, it is possible to find in time by a special node that processes Perform abnormal problem, also can make reply in time according to this problem.Such as, described abnormality processing node will appear from the place of problem Reason task corresponding to node processes message and processes message by message channel transmission to another standby this task that is able to carry out Process node, so, when the execution result of this standby process node is correct, additionally it is possible to continue executing with this task requests, should Because of middle a certain link, task requests will not occur that mistake stops.
For example, task requests 1, task requests 2 are required to use that the A shown in Fig. 2 processes node, B processes node, C Process node；And it being required to B process node execution B2 scheduled operation, during if performing task requests 1, it is pre-that B processes node execution B2 Fixed operation occurs abnormal, if the data of clean-up task request 1 generation not in time, then affects the implementation progress of task requests 2.And adopt Message is processed, owing in time data produced by task requests 1 being carried out with abnormality processing node special disposal abnormal task Process, the execution of task requests 2 will not be caused big impact.
The most for example, task requests 1 needs to use the A process node shown in Fig. 2, B processes node, C processes node, and Need A to process node and perform A3 scheduled operation, need B to process node and perform B2 scheduled operation, need C process node to perform C1 pre- Fixed operation；During if performing task requests 1, B processes node and performs B2 scheduled operation and occur abnormal, then abnormality processing node can be by Notification message passage processes node to standby B ' and sends task process message, and notice B ' processes node and performs B2 scheduled operation, So, when the execution result that B ' processes node execution B2 scheduled operation is correct, C processes node and can continue to perform the predetermined behaviour of C1 Make, so, task requests 1 will be caused to continue executing with because B processes the execution result mistake of node.
Here, described step 102 and described step 103 are coordination.I.e. after step 101, if when described n-th makes a reservation for When operation performs correct, perform step 102；If when described n-th scheduled operation performs mistake, performing step 103.
In an optional embodiment, the described execution result according to the n-th scheduled operation sends anti-to described message channel After feedback message, described method also includes:
Control node and judge whether the execution result of described n-th scheduled operation performs correctly based on described feedback message, its In, described feedback message includes the execution result of the n-th scheduled operation；
When described n-th scheduled operation performs mistake, control the abnormality processing node in node notice system, by exception Reason node task based access control process inventory sends, to described message channel, the abnormal task process formed based on described feedback message and disappears Breath；Wherein, described task processes the N number of described process node that inventory includes performing described task requests, and N number of described process The execution sequence of the scheduled operation that node performs.
In another optional embodiment, described method also includes:
Described n-th processes node judges whether described n-th scheduled operation performs correctly；
When described n-th scheduled operation performs occur abnormal, then according to the execution result of the n-th scheduled operation to described message Passage feedback Equations of The Second Kind message；Wherein, described Equations of The Second Kind message includes that described n-th processes the execution result of node, at described n-th Abnormality processing node and described task that reason node determines process inventory；
The abnormality processing node determined by described n-th process node processes inventory to described message channel based on described task Send the abnormal task formed based on described Equations of The Second Kind message and process message.
Here, the abnormality processing node in system can be multiple.
When continuing to perform a certain task requests, A processes node to be needed to perform A3 scheduled operation, and B processes node to be needed to hold Row B2 scheduled operation, C processes node to be needed to perform C1 scheduled operation；And execution sequence is A3 scheduled operation, B2 scheduled operation, C1 Illustrate as a example by scheduled operation.As it is shown in figure 5, A processes node obtains A task process message from message channel, when A process When node performs the execution result of A3 scheduled operation for performing correct, B process node obtains the process of B task from message channel and disappears Breath, when B processes the execution result of node execution B2 scheduled operation for performing correct, C processes node and obtains C from message channel Task processes message, and when C processes the execution result of node execution C1 scheduled operation for performing mistake, abnormality processing node is from institute State message channel obtains and process, based on C, the abnormal task process message that the feedback message of node is formed, and according to described exception Task processes message and performs abnormality processing operation.
In one embodiment, the described abnormal task formed based on described feedback message processes message, including:
Determine each process node needing to perform abnormality processing operation and the order performing abnormality processing.
Such as, described abnormality processing operates, including: produced data will delete during performing described task requests Remove.
So, when reusing same memory space, it is simple to when performing other task requests or re-execute described During task requests, the current task requests performed is interfered by the produced data relevant to described task requests before.
For another example, described abnormality processing operates, including: perform rolling back action.
Here, described rolling back action refers to return to program or data the behavior of last correct status.
When continuing to perform a certain task requests, A processes node to be needed to perform A3 scheduled operation, and B processes node to be needed to hold Row B2 scheduled operation, C processes node to be needed to perform C1 scheduled operation；And execution sequence is A3 scheduled operation, B2 scheduled operation, C1 Illustrate as a example by scheduled operation.Performing the execution result of A3 scheduled operation for execution correctly when A processes node, B processes node The execution result performing B2 scheduled operation is correct for performing, and C processes node and performs the execution result of C1 scheduled operation for perform mistake Mistaking, abnormality processing node obtains from described message channel and processes at the abnormal task of feedback message formation of node based on C Reason message, and process message execution rolling back action operation according to described abnormal task, abnormality processing node is from described message channel Middle acquisition processes, based on C, the abnormal task process message that the feedback message of node is formed, and disappears according to the process of described abnormal task Breath performs abnormality processing operation, and wherein, described abnormal task processes message and includes: C processes node to be needed to perform E1 scheduled operation, B processes node to be needed to perform E1 scheduled operation, and A processes node to be needed to perform E1 scheduled operation；And execution sequence is that C processes joint Point, B process node, A processes node, and wherein, described E1 scheduled operation represents rolling back action；Make a reservation for when C processes node execution E1 During end of operation, it is complete that B processes node execution E1 scheduled operation, when A process node execution E1 scheduled operation is complete, for this The rolling back action of business request completes.
In an optional embodiment, the order of described execution abnormality processing is: occur different with the current task requests that performs Normal process node is starting point, enters according to the inverted order mode of each execution sequence processing node of task requests described in executed Row sequence.
For example, as shown in Figure 6, abnormality processing node obtains from described message channel and processes the anti-of node based on C The abnormal task that feedback message is formed processes message, and according to the process message execution abnormality processing operation of described abnormal task, wherein, Described abnormal task processes message and includes: C processes node to be needed to perform E1 scheduled operation, and B processes node needs execution E1 to make a reservation for Operation, A processes node to be needed to perform E1 scheduled operation；And execution sequence is that C processes node, B processes node, A processes node.As Shown in Fig. 6, C processes node and obtains C abnormal task process message from message channel, performs E1 scheduled operation when C processes node Time complete, B processes node and obtains B abnormal task process message from message channel, when B process node execution E1 scheduled operation is complete Bi Shi, A process node and obtain A abnormal task process message from message channel, when A process node execution E1 scheduled operation is complete Time, the abnormality processing for this task requests has operated.
