jbpm事件

一、流程图

二、代码实现

 1>test.jbpl.xml

 <?xml version="1.0" encoding="UTF-8"?>

 <process name="test" xmlns="http://jbpm.org/4.4/jpdl">



     <!-- 流程启动事件 -->
     <on event="start">
         <event-listener class="com.njupt.k_event.EventListenerImpl"></event-listener>
     </on>

     <!-- 流程结束事件 -->
     <on event="end">
         <event-listener class="<span style="font-family: Arial, Helvetica, sans-serif;">"com.njupt</span><span style="font-family: Arial, Helvetica, sans-serif;">.k_event.EventListenerImpl"></event-listener></span>
     </on>




     <start name="start1" g="136,73,48,48">
         <transition name="to task1" to="task1" g="-53,-17" />

         <!-- Start活动只有离开活动事件 -->
         <on event="end">
             <event-listener class="<span style="font-family: Arial, Helvetica, sans-serif;">"com.njupt.</span><span style="font-family: Arial, Helvetica, sans-serif;">k_event.EventListenerImpl"></event-listener></span>
         </on>

     </start>


     <task name="task1" g="127,168,92,52" assignee="张三">
         <transition name="to end1" to="end1" g="-47,-17" />

         <!-- 进入活动事件 -->
         <on event="start">
             <event-listener class=<span style="font-family: Arial, Helvetica, sans-serif;">"com.njupt.</span><span style="font-family: Arial, Helvetica, sans-serif;">k_event.EventListenerImpl"></event-listener></span>
         </on>

         <!-- 离开活动事件 -->
         <on event="end">
             <event-listener class="<span style="font-family: Arial, Helvetica, sans-serif;">"com.njupt.</span><span style="font-family: Arial, Helvetica, sans-serif;">k_event.EventListenerImpl"></event-listener></span>
         </on>

     </task>

     <end name="end1" g="156,269,48,48">

         <!-- End活动只有进入活动事件 -->
         <on event="start">
             <event-listener class="<span style="font-family: Arial, Helvetica, sans-serif;">"com.njupt.</span><span style="font-family: Arial, Helvetica, sans-serif;">k_event.EventListenerImpl"></event-listener></span>
         </on>

     </end>

 </process>

2>编写事件处理类

 package com.njpt.k_event;

 import org.jbpm.api.listener.EventListener;
 import org.jbpm.api.listener.EventListenerExecution;

 public class EventListenerImpl implements EventListener {

     @Override
     public void notify(EventListenerExecution execution) throws Exception {
         System.out.println("事件触发了, " + execution.getActivity());
     }

 }

三、编写流程测试类

 package com.njupt.k_event;

 import java.io.InputStream;

 import org.jbpm.api.Configuration;
 import org.jbpm.api.ProcessEngine;
 import org.jbpm.api.ProcessInstance;
 import org.junit.Test;

 public class ProcessTest {

     private ProcessEngine processEngine = Configuration.getProcessEngine();

     @Test
     public void test() throws Exception {
         // 1，部署流程定义
         InputStream in = getClass().getResourceAsStream("test.jpdl.xml");
         processEngine.getRepositoryService()//
                 .createDeployment()//
                 .addResourceFromInputStream("test.jpdl.xml", in)//
                 .deploy();

         // 2，启动流程实例
         processEngine.getExecutionService().startProcessInstanceByKey("test");
     }

     @Test
     public void testCompleteTask() throws Exception {
         String taskId = "350008";
         processEngine.getTaskService().completeTask(taskId);
     }

 }
