##  一、[添加多个节点详见demo37](https://gitee.com/FlowableDemo/demo37)





## 二、添加事件监听器

- 实现FlowableEventListener接口

```
/**
 * 事件监听：流程实例执行完处理业务数据
 *
 */
public class CustomFlowableEventListener implements FlowableEventListener {
	
	private ProcessEngineConfigurationImpl processEngineConfigurationImpl;

	@Override
	public void onEvent(FlowableEvent event) {
		FlowableEngineEventType flowableEventType = (FlowableEngineEventType) event.getType();
		System.out.println("事件类型: " + flowableEventType);
		switch (flowableEventType) {
		case PROCESS_COMPLETED:
			FlowableEntityEventImpl flowableEntityEventImpl = (FlowableEntityEventImpl) event;
			SqlSessionFactory sqlSessionFactory = processEngineConfigurationImpl.getSqlSessionFactory();
			SqlSession sqlSession = sqlSessionFactory.openSession();
			CreationMapper cm = sqlSession.getMapper(CreationMapper.class);
			cm.updateState(flowableEntityEventImpl.getProcessInstanceId());
			sqlSession.commit();
			sqlSession.close();
			break;

		default:
			break;
		}

	}

	@Override
	public boolean isFailOnException() {
		return false;
	}

	@Override
	public boolean isFireOnTransactionLifecycleEvent() {
		return false;
	}

	@Override
	public String getOnTransaction() {
		return null;
	}
	public ProcessEngineConfigurationImpl getProcessEngineConfigurationImpl() {
		return processEngineConfigurationImpl;
	}

	public void setProcessEngineConfigurationImpl(ProcessEngineConfigurationImpl processEngineConfigurationImpl) {
		this.processEngineConfigurationImpl = processEngineConfigurationImpl;
	}
}
```

- 在配置文件flowable-context.xml中配置监听器

```
<property name="eventListeners">
    <list>
        <bean class="com.flowable.demo.CustomFlowableEventListener" >
        <property name="processEngineConfigurationImpl" ref="processEngineConfiguration"	</property>
        </bean>
    </list>
</property>
```



## 三、实践测试

- 运行complete，依次完成任务，当实例执行完，ACT_CREATION表中的STATE_被值为１
