FlowAble監聽的兩個監聽taskListener 和 executionListener

注意如果想要讓flowable或activiti能獲取到service 那麼最好在呼叫的service 用 Component 註解 並指定名稱

例如:@Component("sequenceFlowListener") 

1、TaskListener  主要是監聽usertask的情況，監聽事件event有4種：

create 建立

assignment 分配人

complete 完成

delete 刪除

程式碼：
@Service
public class CountersignTaskListener implements TaskListener{
    @Override
    public void notify(DelegateTask delegateTask) {
        System.out.println(
 
"aaaaaaaaaaaaaaaaaaaaaaaaaa");
        System.out.println("aaaaaaaaaaaaaaaaaaaaaaaaaa");
    }
}
xml:

<userTask id="USERTASK" name="USERTASK" >
  <extensionElements>
    <activiti:taskListener event="create" delegateExpression="${sequenceFlowListener}"/>
  </extensionElements>
</userTask>
2
 
、ExecutionListener 主要是監聽 sequenceFlow的監聽器，監聽事件有3種

start 開始

take 啟用

end 結束

程式碼如下；

@Component("sequenceFlowListener")
public class SequenceFlowListener implements ExecutionListener {

    @Override
    public void notify(DelegateExecution execution) {

        System.out.println("aaaaaaaaaaaaaa");
        execution.setVariable(
 
"審批人","111");
        System.out.println("aaaaaaaaaaaaaa");
    }

}
xml:

 <sequenceFlow id="sequenceFlow-b619e9a1-9e15-4ada-9bf6-54e0fcf7f6c8" name="條件1" sourceRef="gateWay-9134083e-a2a3-4021-9628-f478602c5933" targetRef="userTask-counterSign-0ae5c7c5-b282-4e4d-b8dd-b3d5fe623583">
      <extensionElements>
        <flowable:executionListener event="take" delegateExpression="${sequenceFlowListener}"></flowable:executionListener>
      </extensionElements>
      <conditionExpression xsi:type="tFormalExpression"><![CDATA[${conditionService.checkCondition(1,'userTask-counterSign-0ae5c7c5-b282-4e4d-b8dd-b3d5fe623583',execution)}]]></conditionExpression>
    </sequenceFlow>
