wujimin commented on issue #693: [SCB-548] support gracefully shutdown
URL:
https://github.com/apache/incubator-servicecomb-java-chassis/pull/693#issuecomment-388683495
in performance test, ShutdownHookHandler will always block shutdown process
for many seconds (wait for timeout for wrong request/response count statistics)
will change statistics from invocation handler to invocation event
after change to invocation event, then reject in invocation handler is too
late
so shutdown hook will rewrite
by new hook, even in performance test, we can shutdown normally in one or
two second.

> 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
