requestcancelactionhandler.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.action;


import org.jbpm.graph.def.ActionHandler;

import org.jbpm.graph.exe.ExecutionContext;

import com.myrequest.*;

public class RequestCancelActionHandler implements ActionHandler {


       public void execute(ExecutionContext executionContext) throws Exception {

              // TODO Auto-generated method stub

              String requestState = (String)executionContext.getContextInstance().getVariable(RequestVariable.requestState);

              

              //只有两种状态下允许撤销
              if(requestState.compareTo(RequestState.REQEUST)==0 || requestState.compareTo(RequestState.CHIEFAPPROVE)==0 ){
                    
                     //如果撤销请求的时候，请求状态为“部门主管批准”状态
                     if(requestState.compareTo(RequestState.CHIEFAPPROVE)==0){
                            executionContext.getContextInstance().createVariable(RequestVariable.isChiefHere,new Boolean(true));
                     }
                     executionContext.getContextInstance().setVariable(RequestVariable.requestState,RequestState.CANCLE );
              }
              else{
                     System.out.println("==can't canel request==");
              }
              System.out.println("=====Action=======RequestCancelActionHandler.execute()==");

       }
