Idea integrates Activiti. The drag-and-drop process of generating bpmn files is the first step in using workflow. Today we take a business scenario as an example, such as file archiving business: file query, creation of temporary directory, file decompression (if it is a compressed package, it needs to be decompressed) , file verification, file archiving, file warehousing, writing cache and logging at the same time;
1. Idea installation plug-in
2. Boot service generated file
Here activiti integrated boot service reference: previous article
3. Right-click the file
Go to view edit page
At this point, you can start dragging and dropping the flowchart.
4. Right click to start
Parameters can be configured after creation
At this time, the bpmn file is changed at the same time, you can see
After that, various events and gateways are configured.
5. Right-click to create a task
configuration parameters
Notice:
1), Class is to specify a business class, such as:
com.nandao.bpm.CommonJavaDelegate2), Expression parses a method using an expression, for example:
${testServer.doWork()}3), Delegate Expression uses a delegate expression to specify an object, the first letter of this object must be changed to lowercase, otherwise an error will be reported:
4) Only one of the above three parameters can be configured, otherwise an error may be reported
Unknown property used in expression: ${XXX} 6. Custom conditions
Judgment parameter isZip==false, decompression will not be performed, conditional judgment, if it is possible to judge isZip==true
In addition: the meaning of xsi:type is unknown, the value is tFormalExpression;
Generally, an exclusive gateway can be added in front, which is more secure, but there are points that need attention.
Note: The exclusive gateway will only select a branch that is true; if two branch conditions are true, the exclusive gateway will select a branch with a smaller id value to execute; if the conditions are not met, the process will end (yes Abnormal end).
7. Parallel Gateway
Note: Parallel Gateway does not parse conditions. Even if a condition is defined in the sequence flow, it will be ignored.
In addition to the two gateways just mentioned, there are also containment gateways and event gateways. You can check them when you use them. The basic idea is the same.
8. Workflow ends
9. The final flow chart
It can also be downloaded and saved to a directory
10. The content of the generated bpmn file

This content can be briefly referred to. In addition, there is an idea integrated activiti drawing method, which is also very good to find on the Internet: two drawing methods
At this point, the entire process of npmn files has been generated. In the next article, we will demonstrate the entire process in practice, so stay tuned!
