log4j不同的日誌輸出到不同的文件中

依賴jar包 log4j-1.2.11.jar 下載地址：http://download.csdn.net/detail/xiao88xin/7320473

主類：Log4jMain.java  

package log4j;

/***

import org.apache.log4j.Logger;

public class Log4jMain {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		/* log4j.properties中如果配置了log4j.Log4jMain 類對應的日誌文件
		 * 打印到對應的文件中，否則打印到根日誌文件中
		 */
		Logger log = Logger.getLogger(log4j.Log4jMain.class);
		log.info("Log4jMain");
		
		
		Test1Logger log1 = new Test1Logger();
		log1.logInfo("Test1Logger");
		
		Test2Logger log2 = new Test2Logger();
		log2.logInfo("Test2Logger");
		

	}

}

打印類： Test1Logger.java、Test2Logger.java

package log4j;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.apache.log4j.Logger;

public class Test1Logger {
	Logger log;
	public Test1Logger(){
		log = Logger.getLogger(log4j.Test1Logger.class);
	}
	public void logInfo(String message){
		log.info(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())+"\t"+message);
	}
}

package log4j;


import java.text.SimpleDateFormat;

import org.apache.log4j.Logger;

public class Test2Logger {
	Logger log;

	}
	public void logInfo(String message){
		log.info(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())+"\t"+message);
	}
}

結果會在F:/logstest目錄下生產3個日誌文件，並做了日誌記錄
