##  一、给缓存中添加单一独立节点

- 创建任务节点:user-d

```java
UserTask userTask = new UserTask();
userTask.setId("user-d");
userTask.setName("user-d");
userTask.setAssignee("demo");
userTask.setBehavior(createBehavior(userTask));
```

- 创建连线:sequence-s1

  ****

```
SequenceFlow sequenceFlow = new SequenceFlow();
sequenceFlow.setId("sequence-s1");
sequenceFlow.setName("sequence-s1");
sequenceFlow.setTargetRef("user-b");
sequenceFlow.setTargetFlowElement(process.getFlowElement("user-b"));
```

- 设置任务节点:user-d的出线


```
userTask.setOutgoingFlows(Arrays.asList(sequenceFlow));
```

- 将任务节点,连线添加到流程中

```
process.addFlowElement(userTask);
process.addFlowElement(sequenceFlow);
```

- 更新缓存

```
ProcessDefinitionCacheEntry processDefinitionCacheEntry = managementService.executeCommand(new GetProcessDefinitionCacheEntryCmd(processDefinitionId));
		processDefinitionCacheEntry.setProcess(process);
```



## 二、实践测试



- 运行demo
- 查看数据库表
- DEBUG看看是否添加成功

```
org.flowable.bpmn.model.Process process2 =managementService.executeCommand(new GetProcessDefinitionCacheEntryCmd(processDefinitionId)).getProcess();
		System.out.println(process2);
```

- 节点跳到刚刚新的节点user-d

```
managementService.executeCommand(new CustomCommonJumpCmd(taskId, "user-d"));
```

- 查看ACT_RU_TASK表可以看到任务已经跳转到了user-d

由于user-d任务节点在缓存中,重启后会丢失,后续可以将其缓存到redis中.

如果要完成任务,需要从缓存中获取节点user-d,详见**completeByCache**方法
