## 一、根据自定义扩展属性，通过服务节点给下一个任务节点配置人

- 定义服务节点处理类

```java
public class AssignToAuditorDelegate implements JavaDelegate,HmXMLConstants {

	public void execute(DelegateExecution execution) {
		
		FlowElement flowElement = execution.getCurrentFlowElement();
		
		FlowNode flowNode = (FlowNode) flowElement;
		
		List<SequenceFlow> sequenceFlows = flowNode.getOutgoingFlows();
		if (sequenceFlows.size() > 0) {
			SequenceFlow sequenceFlow = sequenceFlows.get(0);
			if (sequenceFlow !=null) {
				
				FlowElement targetFlowElement = sequenceFlow.getTargetFlowElement();
				if( targetFlowElement instanceof UserTask) {
					
					String approval = targetFlowElement.getAttributeValue(NAMESPACE, APPROVAL);
					
					System.out.println("下一个审核节点: " + approval);
					
					if ("主管审2".equals(approval)) {
						execution.setVariable("assignees", Arrays.asList("manager1","manager2","manager3"));
					}else if ("总监审3-1".equals(approval)) {
						execution.setVariable("assignees", Arrays.asList("boss31","boss32","boss33"));
					}else if ("总监审3".equals(approval)) {
						execution.setVariable("assignees", Arrays.asList("boss"));
					}else {
						execution.setVariable("assignees", Arrays.asList("admin"));
					}
				}
			}
			
		}
	}

}
```



## 二、定时任务

三种方式指定定时执行：

- **timeDate**方式

```
<!-- 在2019-01-21T12:13:14执行一次-->
<timerEventDefinition> 
	<timeDate>2019-01-21T12:13:14</timeDate> 
</timerEventDefinition>
```

- **timeDuration**方式

```
<!-- 10天后开始执行-->
<timerEventDefinition> 
	<timeDuration>PT10D</timeDuration>
</timerEventDefinition>
```

- **timeCycle**方式

```
<!-- 从2019-01-21T16:42:11+00:00开始执行3次，每次间隔10小时-->
<timerEventDefinition> 
	<timeCycle activiti:endDate="2019-01-21T16:42:11+00:00">R3/PT10H</timeCycle>
</timerEventDefinition>
```



## 三、开启定时配置开关

- 在flowable-context.xml配置定时开关

```
<property name="asyncExecutorActivate" value="true" />
```



## 四、邮件配置

- 在flowable-context.xml配置邮件信息

```
<property name="mailServerHost" value="your mailServerHost "/>
<property name="mailServerPort" value="your mailServerPort"/>
<property name="mailServerDefaultFrom" value="your mailServerDefaultFrom"/>
<property name="mailServerUseSSL" value="true"/>
```



## 五、实践测试

- 运行demo
- 完成所有任务后执行sleep方法
