Specific embodiment
Many details are explained in the following description in order to fully understand the application.But the application can be with
Much it is different from other modes described herein to implement, those skilled in the art can be without prejudice to the application intension the case where
Under do similar popularization, therefore the application is not limited by following public specific implementation.
The application provides a kind of rollback processing method, and the application also provides a kind of rollback processing unit and a kind of electronics
Equipment.It is described in detail one by one below in conjunction with the attached drawing of embodiment provided by the present application, and to each step of method
Suddenly it is illustrated.
A kind of rollback processing method embodiment provided by the present application is as follows:
Referring to attached drawing 2, it illustrates a kind of schematic diagrames of rollback treatment process embodiment provided by the present application.
Step 1, the rollback request initiated for workflow is obtained.
Workflow described in the embodiment of the present application, refer to a part or whole part of business procedure under computer application environment from
Dynamicization, a workflow can split into different tasks, these tasks obtained after fractionation are for realizing work
The corresponding function of stream.Workflow A as shown in Fig. 2 is split as n task: task 1 to work according to function
Task n.
In the specific implementation, it before this step obtains the rollback request initiated for the workflow, also needs to execute
For the initialization operation of the workflow, and for the initialization operation of the corresponding rollback task of the task.Its
In, the initialization operation of the workflow specifically includes and executes request for the workflow according to what is got in advance, just
In addition to this work of the beginningization workflow is appointed, further include to the workflow to the initialization operation of the workflow
The execution sequence of task is initialized.Workflow A as shown in Fig. 2, the n task of initial work stream A,
And the n task of initial work stream A executes sequence, executes sequence after initialization are as follows: from task 1 to work
Task n is successively sequentially executed.
The initialization operation of the corresponding rollback task of the task, specifically includes for the workflow all working
Task each of works as task, performs the following operations: judging whether the task meets preset rollback condition, if
It is to initialize the corresponding rollback task of the task, and the rollback task that the task after initialization is corresponding
It is written in the rollback mapping relations.It is default to refer to that the execution time of task is more than or equal to for the rollback condition
Time threshold.By the initialization operation of the corresponding rollback task of the task, for the major tasks of the workflow
Task realizes rollback definition, and the task more long than the workflow execution time as will be described is thought as major tasks, right
These major tasks tasks realize rollback definition, and implementation is relatively simple.Workflow A as shown in Fig. 2, the n of workflow A
In a task, the execution time of task 2 and task 3 is long, therefore appoints for task 2 and work
Rollback definition is realized in business 3.
In practical applications, any one task of the workflow, corresponding rollback process might not relate to
An and rolling back action, it is also possible to multiple rolling back action coordinateds be needed to realize rollback process jointly.In response to this, originally
Apply for rollback task described in embodiment, can also be the rollback link being made of at least one rolling back action.Appoint in the rollback
On the basis of rollback link of the business at least one rolling back action composition, correspondingly, the corresponding rollback task of the task
Initialization operation, comprising: configure the rolling back action for including in the corresponding rollback link of the task and the rollback
The rollback for the rolling back action for including in link executes sequence.
As described above, the rollback link that rollback task is made of at least one rolling back action, for the workflow
The rollback of the task can be achieved if there is multiple rolling back actions or a combination thereof for any one task, then right
For the task, multiple rolling back actions or a combination thereof according to rollback execution sequence composition one or more of rollback chains
Road can be used as the rollback task of the task.As it can be seen that any one task of the workflow, corresponding time
It rolls across journey not to be fixed and invariable, a task can also pass through any one rollback link in a plurality of rollback link
Realize rollback, and the rollback result of the corresponding all rollback links of the task is all the same, it is ensured that rollback result it is accurate
Property and uniqueness.
Workflow A as shown in Fig. 2, wherein the rollback task of task 2 are as follows: rolling back action 1 and 2 groups of rolling back action
At rollback link not only to initialize its corresponding rolling back action when the rollback task to task 2 initializes
1 and rolling back action 2, will also to rolling back action 1 and rolling back action 2 in rollback process execute sequence (rollback executes sequence) into
Row initialization.The rollback task of task 3 is the rollback link that rolling back action 3 is individually composed, and need to only be carried out to rolling back action 3
Initialization.
In addition to this, in practical applications, also it is not precluded under some special screnes, it is each when business need workflow
It, can be by the way that the numerical value of above-mentioned preset time threshold will be adjusted, by above-mentioned preset time when rollback may be implemented in a task
Threshold value is set as a lesser value, so that all working task of the workflow be made to be able to achieve rollback definition.
It, might not just because of above-mentioned implementation when the task for the workflow realizes that rollback defines
It is all working task realization rollback definition for the workflow, therefore, by the way that the rollback mapping relations are arranged, to tie up
Protect the corresponding rollback task corresponding relationship of the task of the workflow.Specifically, in the rollback mapping relations
It records the task that all realization rollbacks of the workflow define and the task that each realization rollback defines is corresponding
Rollback task.
For example, the rollback mapping table of following offers:
| Workflow ID | Task ID | Rolling back action ID |
| Workflow A | Task 2 | Rolling back action 1 |
| Workflow A | Task 3 | Rolling back action 3 |
| Workflow B | Task 3 | Rolling back action 1 |
| Workflow B | Task 16 | Rolling back action 2 |
| Workflow C | Task 8 | Rolling back action 3 |
| Workflow C | Task 10 | Rolling back action 1 |
Attached drawing 2 is compareed, the task 2 and task 3 that record has workflow A realization rollback to define in upper table, simultaneously
Also record has the first rolling back action 1 in the corresponding rollback link of task 2 (rolling back action 1- > rolling back action 2), and
The rollback link that the corresponding rolling back action 3 of task 3 is individually composed.Similar, also record has workflow B and work in upper table
Stream C respectively realizes the task that rollback defines, and respectively realizes the corresponding rollback link of task that rollback defines.
It, can be using rolling back action as realization rollback definition when the task for the workflow realizes that rollback defines
The most basic unit of process, and the execution frame of these most basic rolling back actions is done one and is abstracted: for same time
Rolling operation, during realizing rollback definition for different workflows, the execution frame of the same rolling back action is identical
, difference is that the service logic data of the rolling back action of different workflow (i.e. different business) have differences.Based on this
One thought is, it can be achieved that the corresponding rolling back action of the task of workflow is shared, i.e., the execution frame of rolling back action is shared,
Only different service logic data need to be configured for the task of different working flow, so as to avoid different business is directed to
The workflow of type develops different rolling back actions respectively, and the task greatly reduced for the workflow is realized back
Cost of implementation when rolling definition.
Specifically, in practical applications, the rolling back action (i.e. the execution frame of rolling back action) can be stored in pre-
If in data storage cell, and the rollback configuration interface configured by the data storage cell is grasped to access the rollback
Make；When the rolling back action for including in the corresponding rollback link of task to the workflow configures, pass through tune
Interface is configured with the rollback, and the rollback behaviour to match with the task of the workflow is read from the data storage cell
Make, and the rolling back action is configured in conjunction with the service logic data of the task, and to the rollback link
The rollback execution sequence for the rolling back action for including in the middle is configured, and the task of the configured workflow is corresponding
The rolling back action for including in rollback link is written in the rollback mapping relations.
However, often will appear new type of service or business scope in practical application, it is being directed to these service class
When type or the workflow of business scope realize that rollback defines, task (the new business of a few thing stream can be inevitably encountered
Function), the work can be created in response to this in the data storage cell and there is no corresponding rolling back action
Make the corresponding rolling back action of task, the rolling back action of creation is registered and is committed in the data storage cell.
In addition, the rolling back action stored in the data storage cell also has configuration dimensional attribute, institute is being called
When stating the rolling back action that rollback configuration interface is read from the data storage cell and the task matches, according to institute
The matching dimensionality for stating workflow is matched from the consistent rolling back action of matching dimensionality for reading configuration dimension and the workflow
It sets；Wherein, the configuration dimension includes at least one of following: type of service, business scope and work stream attribute.
The above-mentioned initialization operation realized for the workflow, and it is corresponding for the task of the workflow
Rollback task initialization operation after, execute the task of the workflow on this basis, executing the work
During stream, if since business needs or other factors cancel the execution of the task of the workflow, and need
When the task for wanting workflow described in rollback to execute, in this step, described time initiated for the workflow is obtained
Rolling request.
Step 2, it according to the rollback mapping relations of preconfigured task and rollback task, determines at the workflow
It is executed at least one rollback of at least one corresponding rollback task of task and the rollback task of the state of execution
Sequentially.
For example, the task 1 of workflow B, corresponding rollback task include:
(1) the rollback link that rolling back action 1 and rolling back action 2 form, rollback execute sequence are as follows: rolling back action 1- > rollback
Operation 2；
(2) the rollback link that rolling back action 1, rolling back action 5 and rollback task 6 form, rollback execute sequence are as follows: rollback behaviour
Make 1- > rolling back action 5- > rolling back action 6.
In a kind of preferred embodiment provided by the embodiments of the present application, this step is according to preconfigured task and returns
The rollback mapping relations of rolling task determine that the workflow is in corresponding at least one rollback times of task of execution state
Before at least one rollback execution sequence of business and the rollback task, the judgement operation of rollback task is executed.The rollback is appointed
Business judgement operation is implemented as follows:
Judge that the workflow is currently at the task of execution state and whether is configured with corresponding rollback task, that is, sentences
Whether the task that the workflow of breaking is currently at execution state has realized that rollback defines, if so, executing this step, really
The fixed rollback mapping relations according to preconfigured task and rollback task determine that the workflow is in and execute shape
At least one rollback of at least one corresponding rollback task of the task of state and the rollback task executes sequence；
If it is not, showing that the workflow is currently at the task of execution state and rollback definition is not implemented, institute is executed
The task that workflow is currently at execution state is stated, next task configured with corresponding rollback task is waited,
The rollback process of the workflow is carried out based on next task configured with corresponding rollback task.
Specifically, appointing if the workflow is currently at the task of execution state and is not configured with corresponding rollback
Business, then wait next task configured with corresponding rollback task, is configured with corresponding rollback task based on next
Task carry out the rollback process of the workflow, specifically realize in the following way:
The task that the workflow is currently at execution state is executed, and is currently at execution shape in the workflow
The task of state performs the following operations after being finished: judging that the workflow is in execution state according to the execution sequence
Task execute after the pending task of next execution whether be configured with corresponding rollback task, if so, if so,
It performs the following operations: determining at least one corresponding rollback task of the pending task and the rollback task
At least one second rollback executes sequence, terminates the execution of the task of the workflow, and hold according to second rollback
Row sequence executes the corresponding rollback task of the pending task.
Workflow A as shown in Fig. 2, if task 1 carries out rollback when executing, since task 1 is not real
Existing rollback definition, cannot achieve the rollback process of workflow A, need to judge whether pending task 2 realizes that rollback defines, such as
The pending task 2 of fruit has realized that rollback defines, then after waiting task 1 to be finished, is based on pending task 2
Corresponding rollback link realizes the rollback process of workflow A.Assuming that pending task 2 is also not carried out rollback definition, then
It need to judge whether pending task 3 realizes that rollback defines, if pending task 3 has realized that rollback defines, etc.
After pending task 2 is finished, returning for workflow A is realized based on the corresponding rollback link of pending task 3
Roll across journey.
Step 3, it terminates and executes the task for being in execution state.
In this step, terminates and execute the task that the workflow is currently at execution state.Work as shown in Fig. 2
Make stream A, if task 2 carries out rollback when executing, on the basis of task 2 has realized rollback definition, terminates work
Stream A is currently at the execution of the task 2 of execution state.If task 3 carries out rollback when executing, in task 3
On the basis of having realized rollback definition, the execution that workflow A is currently at the task 3 of execution state is terminated.
Step 4, the corresponding rollback of the task in execution state is executed according to the rollback execution sequence to appoint
Business.
Above-mentioned steps 2 determine the work according to the rollback mapping relations of preconfigured task and rollback task
At least one rollback of stream at least one corresponding rollback task of task and the rollback task in execution state
Sequence is executed, and above-mentioned steps 3 have terminated the execution of the task of the workflow, on this basis, in this step, pressed
The corresponding rollback task of task for being in execution state is executed according to the rollback execution sequence.As described above, described
The rollback task of task is the rollback link of at least one rolling back action composition, it is preferred that this step is according to the rollback
Execution sequentially executes the corresponding rollback task of task in execution state, in particular to jumps to described be in and holds
The first rolling back action for including in the corresponding rollback link of the task of row state, and according to the rollback execution sequence from
First rolling back action starts successively to execute all rolling back actions for including in the rollback link.
Workflow A as shown in Fig. 2, wherein the corresponding rollback task of task 2 is rolling back action 1 and rolling back action
The rollback link of 2 compositions, rollback execution sequence is rolling back action 1- > rolling back action 2, if task 2 is returned when executing
Rolling, on the basis of the execution of above-mentioned termination task 2, jumps to first in the corresponding rollback link of task 2
Rolling back action: rolling back action 1 successively executes rolling back action 1 and rolling back action 2 since rolling back action 1.Task 3 is corresponding
Rollback task be the rollback link that is individually composed of rolling back action 3, if task 3 carries out rollback when executing, at above-mentioned end
Only on the basis of the execution of task 3, the rolling back action 3 in the corresponding rollback link of task 3 is jumped to, and execute
Rolling back action 3.
In the specific implementation, the rollback processing method provided by the present application, is also based on preset data base administration
