Description

Examination and approval method for complex workflow and designated approver

Technical Field

The invention relates to the technical field of multi-process data processing, in particular to an approval method aiming at complex workflows and designated approvers.

Background

Activiti is an open-source workflow engine, and when facing countersigning (multi-person examination and approval), the existing technical scheme mainly comprises the following steps:

1. when drawing a BPMN graph, setting three parameters of loop cardinality, Collection and Element variable for a user task, and simultaneously setting assignment as an EL expression to realize the task, wherein in the process operation, multiple task executors are specified in two layers of variables according to configured Collection transmission process variables, and if partial persons pass through the task executors, the Completion condition needs to be set, and the task termination condition is set by the EL expression.

2. Setting an EL expression for a candidate user when drawing a BPMN graph, specifying a candidate through a variable at the beginning of an example, completing the task by replacing the task with a candidate removing operation, and completing the task when the number of candidates is less than a threshold value.

3. When drawing the BPMN graph, a gateway is utilized to draw a plurality of user tasks, and the access conditions of the gateway are configured to meet the countersigning requirement.

There are some inevitable problems with all three of the above cases: firstly, the flow chart needs to be adjusted according to a specific task flow when the flow chart is drawn by all three schemes, wherein the scheme 3 is the most serious, the scheme 1 and the scheme 2 at least need to know the passing proportion when drawing, the scheme 3 needs to know the number of people who specifically (possibly) participate in approval, so that high coupling phenomenon occurs between business and the flow chart, and the multiplexing of the flow chart is not facilitated, secondly, the EL expressions are needed in the schemes 1 and 2, when the flow is started, if the value needed by the EL expressions cannot be correctly specified, the flow cannot be correctly operated, and finally, the three schemes cannot be considered in the case that multiple groups of multiple conditions need to be approved, and the requirements cannot be met.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides an approval method aiming at a complex workflow and a specified approver, which is used for solving the problem that the condition that multiple groups of multiple conditions need to be approved cannot be realized in the prior art.

The technical scheme adopted by the invention is as follows: an approval method for complex workflows, comprising the steps of:

s1: creating a process instance using the configuration information;

s2: creating a task in a process instance;

s3: triggering a task to create a global listener;

s4: reading configuration information of a current task;

s5: judging whether the configuration information of the current task has a plurality of pieces of configuration information, if so, executing S6, and if not, executing S7;

s6: creating a secondary parent task, dispatching configuration, and executing S3;

s7: creating a subtask for each approver in the configuration;

s8: the sub task is completed in the S7, and a task completion global monitor is triggered;

s9: judging whether the parent task is owned, if yes, executing S10, and if not, executing S2;

s10: reading configuration information stored in a parent task, and acquiring the number of subtasks related to the parent task;

s11: judging whether the current task is in accordance with the completion condition of the parent task after being completed, if yes, entering S12, and if not, ending the monitoring process

Preferably, the method for determining whether the completion condition of the parent task is met after the current task is completed in S11 includes: and judging whether the signing subtask is completely finished and/or whether the number of partial approval persons reaches a threshold value.

Preferably, in S12, after the parent task is completed, the configuration information and the final state of the process instance are stored, and are used for checking and auditing the process approval process.

The invention also provides an approval method for the workflow system of the specified approver, which comprises the following steps:

s1: acquiring configuration information;

s2: judging whether the subtask exists, if yes, executing S3, and if not, executing S4;

s3: deleting the existing subtask;

s4: and establishing a new subtask according to the configuration to complete the process.

Compared with the prior art, the scheme of the invention mainly comprises the following steps:

1. the service is low coupled with the flow chart, which is beneficial to the multiplexing of the flow chart. In the scheme, when the flow chart faces a complex countersign task, the flow chart can be represented by only one user task, almost no extra configuration is needed under the condition of ensuring that the identification is not conflicted, and meanwhile, the specific meanings of all stages in the flow chart are blurred, so that the flow chart can be adapted to a plurality of business flows, and even if the specific business flows have certain differences (mainly on examination and approval conditions and personnel), the same flow chart can be used.

2. And multiple groups of multi-condition examination and approval are supported. According to the scheme, multiple levels of subtasks are used, so that multiple independent subtask groups with different conditions can exist in the same task stage, and the original unsupported multiple-group multi-condition approval can be realized.

3. According to the scheme, an EL expression is not used, the threshold of entry for drawing the flow chart is reduced, learning and use of a user are facilitated, the number of user tasks under complex conditions is combined, and workload for drawing the flow chart is reduced.

4. The scheme supports the dynamic designation of the approvers and the approval schemes in the subsequent steps in the process execution, allows the executors to designate tasks in batches step by step, executes the method, and allows the approvers to designate a plurality of groups of different approval requirements to approve one task for a plurality of times.

1. the flow chart is as follows: the process defined by BPMN is uploaded and stored in an engine in the form of xml, and the function of the process is to define the form of a certain (class) process, and is not a specific process.

2. And (3) user tasks: the graphical representation of "approval" in fig. 3 shows a certain approval stage, which is not identical to the "task" described below.

3. Example of the procedure: for example, according to a flow chart, a workflow is generated that is associated with a specific service and can be executed, where the flow includes one or more tasks being executed.

4. Task: in the workflow instance, a task is called a parent task if the task is depended on by other tasks, is called a child task if the task is depended on by other tasks, is called an N-level parent task if the parent task is also depended on by other tasks, when the task depended on by the task is destroyed or completed, the task is synchronously destroyed, and only the current task is created when the instance runs.

5. An approver: the object of delegation of a task is unique to the approver of the task.

6. Process variables: data present in the instance is not destroyed as the task ends.
