## 參考文章 ##

使用Servlet容器執行（Tomcat、Jetty等） ## 不可取

• 增加複雜性（埠，管理）
• 浪費資源（記憶體）

自建Main方法類來執行（Spring容器） ## 不建議

• dubbo本身提供的高階特性沒用上
• 自己編寫的啟動類可能會有缺陷

使用Dubbo框架提供的Main方法類來執行（Spring容器） ## 建議使用

• 框架本身提供（com.alibaba.dubbo.container.Main）
• 可實現優雅關機
  關機的時候，伺服器有可能還在處理業務，如果直接停止伺服器，有可能造成資料的丟失，優雅關機就是不再接受新的請求，等待一段時間（處理未處理完的請求），再關機。
