Maven 项目结构:

src
 |-main
    |-java
        |-com
            |-xxx
                |-XxxThreadPool.java (实现ThreadPool接口)
    |-resources
        |-META-INF
            |-dubbo
                |-org.apache.dubbo.common.threadpool.ThreadPool (纯文本文件,内容为:xxx=com.xxx.XxxThreadPool)

XxxThreadPool.java:

package com.xxx;
 
import org.apache.dubbo.common.threadpool.ThreadPool;
import java.util.concurrent.Executor;
 
public class XxxThreadPool implements ThreadPool {
    public Executor getExecutor() {
        // ...
    }
}

META-INF/dubbo/org.apache.dubbo.common.threadpool.ThreadPool:

xxx=com.xxx.XxxThreadPool
