"Application" Activiti the simple application of the combination of listening and business particles (III.) __ Workflow

Activiti simple application, the application of monitoring to achieve a simple business particles and workflow integration, so that the process driven business particles to carry out the process, the flow chart of the application of multiple branches, and the process of judgment value set as parameters, from the foreground pass past.

New normal Java class:

Package Com.tgb.itoo.activiti.controller;

public class XS {public

	static void SayHello () {
		System.out.println ("88xvshu");
	}
	
	

New Activiti Listener class:

Package Com.tgb.itoo.activiti.controller;

Import Org.activiti.engine.delegate.DelegateTask;
Import Org.activiti.engine.delegate.TaskListener;

public class Xvshudelegate implements tasklistener{
	/**
	 * */
	private static final long Serialversionuid = 1L;

	@Override public
	void Notify (Delegatetask delegatetask) {		
		xs. SayHello ();
	}
		

Similar Java classes and listening classes need to create 3 more

Business flow chart as shown:

The process variable's property setting (Jingyuan-${result==flowjingyuan},milaoshi-${result==flowmilaoshi}) is shown in the figure:

The resulting configuration file is as follows:

Execution results:

Summarize:

The first explanation is that all of the pauses that exist on the client are non-existent in real-world development, here just to pass the variable, tell the workflow how to continue to execute to the next node, in the real development business is different people to handle different tasks, each query only query their own tasks, Workflows are automatically executed only when their own tasks are completed.

Explain the results of the execution:

The Xvshu node is executed immediately after the workflow is started, but the parameters of the next node need to be entered when the Xvshu node is processed, and when the input Result==flowjingyuan, the Jingyuan node is executed immediately, and the output jingyuan88, Processing Jingyuan nodes also need to enter the next node parameters, when the input content Result==flowhaiyan immediately execute Haiyan node, output 88guhaiyan, processing Guhaiyan node, you need to enter the next node parameters, Because the next node of the Haiyan node ends and there is no condition limit, entering any information will end.
