扩展示例

  • Maven 项目结构:
    src
     |-main
        |-java
            |-com
                |-xxx
                    |-XxxContainer.java (实现Container接口)
        |-resources
            |-META-INF
                |-dubbo
                    |-org.apache.dubbo.container.Container (纯文本文件,内容为:xxx=com.xxx.XxxContainer)
    
  • XxxContainer.java:
    package com.xxx;
    org.apache.dubbo.container.Container;
    public class XxxContainer implements Container {
        public Status start() {
            // ...
        }
        public Status stop() {
            // ...
        }
    }
    
  • META-INF/dubbo/org.apache.dubbo.container.Container:
    xxx=com.xxx.XxxContainer
