dosomethingdecisionhandler.java

这是在JAVA 环境用 JBPM 架构编写的一一套 请假流程实例

package com.myrequest.decision;


import org.jbpm.graph.exe.ExecutionContext;

import org.jbpm.graph.node.DecisionHandler;

import com.myrequest.*;

public class DoSomethingDecisionHandler implements DecisionHandler {


	

       public String decide(ExecutionContext executionContext) throws Exception 
       {
    	   System.out.println("=====Decision=======DoSomethingDecisionHandler.decide()==");
              String requestState = (String)executionContext.getContextInstance().getVariable(RequestVariable.requestState);

              if(requestState.compareTo(RequestState.APPROVE)==0)
              {
                     return "Tr_Approve";
              }
              else if(requestState.compareTo(RequestState.DISAPPROVE)==0)
              {
                     return "Tr_NotApprove";
              }
              else if(requestState.compareTo(RequestState.CANCLE)==0)
              {
                     return "Tr_Cancel";
              }
              else
              {        
                     System.out.println("==状态不对==");
                     throw new Exception("到达的状态不对，为:"+requestState);
              }

       }
