##  一、给缓存中添加多个节点

- 详见AddNode.addMulitiNode方法



## 二、持久化到数据库

- 执行脚本db/init.sql

- 在flowable-context.xml配置文件中添加mapper配置

```
  <property name="customMybatisMappers">
	        <set>
	        	<value>com.flowable.demo.mapper.CreationMapper</value>
	        </set>
</property>
```

- 保存到数据库

```
AddNode.persistenDataToDataBase方法
```

## 三、引擎启动从数据库加载临时节点到缓存

- 在flowable-context.xml配置文件中添加引擎监听器配置

```
<property name="processEngineLifecycleListener"  ref="studyProcessEngineLifecycleListener" />
```

- 流程启动时候加载临时节点数据到缓存

```java
public void onProcessEngineBuilt(ProcessEngine processEngine) {
        System.out.println("－－－－－－－流程引擎开始,加载多节点数据到缓存－－－－－－－－－－ " );
        ProcessEngineConfigurationImpl processEngineConfiguration = (ProcessEngineConfigurationImpl) processEngine
				.getProcessEngineConfiguration();
		SqlSessionFactory sqlSessionFactory = processEngineConfiguration.getSqlSessionFactory();
		SqlSession sqlSession = sqlSessionFactory.openSession();
		List<ActCreation>  actCreations = sqlSession.selectList("com.flowable.demo.mapper.CreationMapper.findAll");
		for (ActCreation actCreation : actCreations) {
			String processInstanceId = actCreation.getProcessInstanceId();
			String processDefinitionId =  actCreation.getProcessDefinitionId();
			TempActivityModel tempActivityModel = JSON.parseObject(actCreation.getProcessText(),TempActivityModel.class);
			new AddNode().addMulitiNode(processDefinitionId, processInstanceId, processEngine, tempActivityModel.getActivitys(), tempActivityModel.getFirst(), tempActivityModel.getLast(), false);
		}

    }
```



## 四、实践测试



- 运行addManyNode，在user-b和user-c之间添加临时节点：user-d，user-e,user-f，并保存到临时表
- 运行getNodeFromCache，从缓存中获取刚刚加的节点user-e
