jbpm知识点——node

node节点类型适用于当你想要在节点中编写自己的代码的情形。通过设置action来帮定我们自己的商业逻辑。

<start-state name="start">
      <transition name="tr1" to="node1"></transition>
   </start-state>
   <node name="node1">
      <action class="com.jeffentest.JeffenActionHandler">
  <msg>HELLO</msg>
   </action>
      <transition name="tr2" to="end1"></transition>
   </node>
   <end-state name="end1"></end-state>

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

 package com.jeffentest;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

public class JeffenActionHandler implements ActionHandler {
  private static final long serialVersionUID = 1L;
  private String msg;
  public void execute(ExecutionContext executionContext) {
   System.out.println(msg+"jeffen");
   //可以指定流程的运行
   //executionContext.leaveNode(transitionName);
    }
 }

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

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());
   jbpmContext.save(processInstance);
   }finally {
     jbpmContext.close();
   }
 }
