URL:
https://github.com/apache/incubator-servicecomb-java-chassis/pull/693#issuecomment-388301667
improve gracefully shutdown process order
```java
private void gracefullyShutdown() {
//Step 1: notify all component stop invoke via BEFORE_CLOSE Event
triggerEvent(EventType.BEFORE_CLOSE);
//Step 2: Unregister microservice instance from Service Center and close
vertx
RegistryUtils.destroy();
VertxUtils.closeVertxByName("registry");
//Step 3: wait all invocation finished
try {
ShutdownHookHandler.INSTANCE.ALL_INVOCATION_FINISHED.acquire();
LOGGER.warn("all invocation finished");
} catch (InterruptedException e) {
LOGGER.error("invocation finished semaphore interrupted", e);
}
//Step 4: Stop vertx to prevent blocking exit
VertxUtils.closeVertxByName("config-center");
VertxUtils.closeVertxByName("transport");
//Step 5: notify all component do clean works via AFTER_CLOSE Event
triggerEvent(EventType.AFTER_CLOSE);
}

> Issue Type: Improvement
> Components: Java-Chassis
> Affects Versions: java-chassis-1.0.0-m2
> Reporter: yangyongzheng
> Assignee: yangyongzheng
> Priority: Major
>
> We did not implement gracefully shutdown yet:
> ```java
> // 当程序退出时，进行相关清理，注意：kill -9 {pid}下无效
> // 1. 去注册实例信息
> // TODO 服务优雅退出
> if (applicationContext instanceof AbstractApplicationContext) {
> ((AbstractApplicationContext)
> applicationContext).registerShutdownHook();
> }
> ```
>
> And had got an issue :
> https://github.com/apache/incubator-servicecomb-java-chassis/issues/685 from
> user.
> So it's time we must do it and remove this TODO
