## 一、自定义命令类

- 流程实例ProcessEngineConfigurationImpl会初始化启动类processInstanceHelper

```java
    public void initHelpers() {
        if (processInstanceHelper == null) {
            processInstanceHelper = new ProcessInstanceHelper();
        }
        if (listenerNotificationHelper == null) {
            listenerNotificationHelper = new ListenerNotificationHelper();
        }
        if (formHandlerHelper == null) {
            formHandlerHelper = new FormHandlerHelper();
        }
    }
```

- 继承ProcessInstanceHelper类，重写createProcessInstance方法即可
- flowable-context.xml中配置processInstanceHelper

```java
<property name="processInstanceHelper" ref="customProcessInstanceHelper"/>
<bean id="customProcessInstanceHelper" class="com.study.demo.CustomProcessInstanceHelper"/>
```



## 二、实践测试



- 运行demo
- 查看数据库表
