@huagetai
Currently the worker server is completely independent of the database. Maybe I didn't understand what you said. Would you like to express your design plan and ideas?

@zhuangchong
ATM:
```java
public class TaskExecuteThread implements Runnable, Delayed {
...
@Override
public void run() {
...
TaskChannel taskChannel = taskPluginManager.getTaskChannelMap().get(taskExecutionContext.getTaskType());
...
}
}
@Component
public class TaskPluginManager {
....
private final PluginDao pluginDao;
....
}
```
In addition, due to the dependence on the dolphinscheduler-service package, spring will automatically inject the datasource
