java - Log4j 打印扩展类名

Question

如何记录扩展类的名称？我想写“FTSControl”而不是“Control”。

public abstract class Control {   
    Logger logger = Logger.getLogger(getClass());   
}

@Component
public class FTSControl extends Control { 

}

<layout class="org.apache.log4j.PatternLayout">
    <param name="ConversionPattern" value="%d{dd.MM.yyyy HH:mm:ss.SSS} %-5p - %C{1}:%m%n" />
</layout>

输出:

09.01.2015 15:58:00.006 WARN  - Control: No files found! Hash:-844390824

我还指出了一些事情，

尽管使用相同的记录器实例，但 Control 和 FTSControl 方法中的 log.info() 调用会打印其自己的类名。我的意思是

FTSControl 打印方法中的 logger.info()

09.01.2015 15:58:00.006 WARN  - FTSControl : No files found! Hash:-844390824

Control打印方法中的logger.info()

09.01.2015 15:58:00.006 WARN  - Control: No files found! Hash:-844390824

//更新完整示例

package com.log;

import org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;

import com.log.abstracttest.ControlAbs;
import com.log.abstracttest.ImosControl;


public class LogMainTest {

    private Logger logger = Logger.getLogger("console");

    public  LogMainTest(){
        DOMConfigurator.configure(this.getClass().getClassLoader().getResource("log4j.xml"));
        logger.info("Initializing...");

        ImosControl control = new ImosControl();
        control.print();
        control.printAll();

    }

    public static void main(String[] args) {
        new LogMainTest();

    }


}


package com.log.abstracttest;

import org.apache.log4j.Logger;

public abstract class ControlAbs {
    Logger logger = Logger.getLogger(this.getClass());

    public void print(){
        logger.info(" print");
    }

}


package com.log.abstracttest;

public class ImosControl extends ControlAbs {

    public void printAll(){
        logger.info("printAll");
    }

}

输出:

10.01.2015 05:38:43.497 INFO  - LogMainTest:Initializing...
10.01.2015 05:38:43.502 INFO  - ControlAbs: print
10.01.2015 05:38:43.503 INFO  - ImosControl:printAll

只需将抽象类中的 Logger logger = Logger.getLogger(getClass()); 替换为

protected final Logger logger = Logger.getLogger(this.getClass());

这样，如果您在 FTSControl 中使用类似 logger.info("test") 的内容，您将在日志中获取实例化类名称
