activiti的ExecutionListener  Expression用法_executionlistener private expression

activiti执行监听器executionListener  Expression用法

 

解决方法：

使用Expression的方式来为开始节点设置监听器处理类，方法表达式Expression内容：${myExecutionListener2.notify2(execution,authenticatedUserId)}，如下所示

<startEvent id="_2" name="StartEvent">

     <extensionElements>

       <activiti:executionListener event="start" expression="${myExecutionListener2.notify2(execution,authenticatedUserId)}"/>

     </extensionElements>

   </startEvent>

 

1.执行监听器executionListener处理类代码，spring会自动注入到activiti表达式${myExecutionListener2.notify2(execution,authenticatedUserId)}中的myExecutionListener2：

@Service

public class MyExecutionListener2{

private static final long serialVersionUID = 8513750196548027535L;  

 

   public void notify2(DelegateExecution execution,String startUserId) throws Exception {

       System.out.println("开始节点" );

   }

 

}
