Maven 项目结构:

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

XxxLoggerAdapter.java:

package com.xxx;
 
import org.apache.dubbo.common.logger.LoggerAdapter;
 
public class XxxLoggerAdapter implements LoggerAdapter {
    public Logger getLogger(URL url) {
        // ...
    }
}

XxxLogger.java:

package com.xxx;
