Maven 项目结构:
src
|-main
|-java
|-com
|-xxx
|-XxxMerger.java (实现Merger接口)
|-resources
|-META-INF
|-dubbo
|-org.apache.dubbo.rpc.cluster.Merger (纯文本文件,内容为:xxx=com.xxx.XxxMerger)
XxxMerger.java:
package com.xxx;
import org.apache.dubbo.rpc.cluster.Merger;
public class XxxMerger<T> implements Merger<T> {
public T merge(T... results) {
// ...
}
}
META-INF/dubbo/org.apache.dubbo.rpc.cluster.Merger:
xxx=com.xxx.XxxMerger
