Super4You opened a new issue #2524: Dubbo优雅关机
URL: https://github.com/apache/incubator-dubbo/issues/2524
 
 
   ### 关于2.6.3版本优雅关机问题
   你好：
   * 
1.经过测试DubboProtocol在关机时在此协议中是独立实现了的https://github.com/apache/incubator-dubbo/issues/2514
 中提到org.apache.dubbo.registry.integration.RegistryProtocol.DestroyableExporter 
这个类为任何协议使用时可以做到优雅关机。
   * 
2.在新版本中debug时发现DestroyableExporter的unexport()方法从没被调用到，追溯到上游代码发现在org.apache.dubbo.bootstrap.DubboBootstrap中registerServiceConfig(ServiceConfig)在全局中没任何调用，serviceConfigList始终为初始化状态，从而在DubboBootstrap.stop()进行关机时，应用启动暴露接口返回的DestroyableExporter没有任何代码去调用其unexport()进行关机前的取消注册与订阅操作以及等待用户设置dubbo.service.shutdown.wait时间操作。
   
   ### 以下为DubboBootstrap类截图

   * 3.水平有限，不知道是我没找到相应的代码或配置，还是有其他问题，请指教一下，谢谢。
   
   ### Environment
   
   * Dubbo version: 2.6.3
   * Operating System version: mac ox
   * Java version: 1.8
