jbpm知识点大全

超状态是一组节点，超状态可以被递归嵌套。超状态可以被用来在流程定义中产生一些层次，例如，一个应用可能要把流程中的所有节点按阶段进行分组。动作可以与超状态事件关联，结果就是一个令牌在某个给定时间可以存在于多个嵌套的节点，这便于检查流程是否执行，比如，是否在启动阶段。在Jbpm模型中，你可以任意分组任何节点到一个超状态。在指定节点时用（/）隔开节点名称，用“..”指向上一层次。

-------------------------------------------

package com.jeffentest;

import org.jbpm.graph.def.ActionHandler;

import org.jbpm.graph.exe.ExecutionContext;

import java.io.*;

public class JeffenActionHandler implements ActionHandler {

private static final long serialVersionUID = 1L;

public void execute(ExecutionContext executionContext) {

String msg = executionContext.getEvent().getEventType()+":"+executionContext.getEventSource().getName();

System.out.println(msg);

}

}

-------------------------------------------------

private static void run(){

JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();

try {

long processInstanceId =1;

processInstance = jbpmContext.loadProcessInstance(processInstanceId);

Token token = processInstance.getRootToken();

System.out.println(token.getNode());

token.signal();

System.out.println(token.getNode());

token.signal();

System.out.println(token.getNode());

token.signal();

System.out.println(token.getNode());

token.signal();

System.out.println(token.getNode());

token.signal();

System.out.println(token.getNode());

token.signal();

System.out.println(token.getNode());

jbpmContext.save(processInstance);

}finally {

jbpmContext.close();

}

}

---------------------------------------------------

运行结果：从进入、离开的顺序看得出嵌套的关系。
