新建log4j.properties:

\#\#\# \\u8BBE\\u7F6E\#\#\#  
log4j.rootLogger = debug,stdout,D,E

\#\#\# \\u8F93\\u51FA\\u4FE1\\u606F\\u5230\\u63A7\\u5236\\u62AC \#\#\#  
log4j.appender.stdout = org.apache.log4j.ConsoleAppender  
log4j.appender.stdout.Target = System.out  
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout  
log4j.appender.stdout.layout.ConversionPattern = \[%-5p\] %d\{yyyy-MM-dd HH:mm:ss,SSS\} method:%l%n%m%n

\#\#\# \\u8F93\\u51FADEBUG \\u7EA7\\u522B\\u4EE5\\u4E0A\\u7684\\u65E5\\u5FD7\\u5230=E://logs/error.log \#\#\#  
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender  
log4j.appender.D.File = /root/logs/log.log  
log4j.appender.D.Append = true  
log4j.appender.D.Threshold = DEBUG  
log4j.appender.D.layout = org.apache.log4j.PatternLayout  
log4j.appender.D.layout.ConversionPattern = %-d\{yyyy-MM-dd HH:mm:ss\}  \[ %t:%r \] - \[ %p \]  %m%n

\#\#\# \\u8F93\\u51FAERROR \\u7EA7\\u522B\\u4EE5\\u4E0A\\u7684\\u65E5\\u5FD7\\u5230=E://logs/error.log \#\#\#  
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender  
log4j.appender.E.File =/root/logs/error.log  
log4j.appender.E.Append = true  
log4j.appender.E.Threshold = ERROR  
log4j.appender.E.layout = org.apache.log4j.PatternLayout  
log4j.appender.E.layout.ConversionPattern = %-d\{yyyy-MM-dd HH:mm:ss\}  \[ %t:%r \] - \[ %p \]  %m%n

新建Test.java：

package com.zhu;  
import org.apache.log4j.Logger;  
/\*\*  
 \*@author linbingwen  
 \*@2015年5月18日9:14:21  
 \*/  
public class Test \{  
    private static Logger logger = Logger.getLogger(Test.class);    
   
    /\*\*  
     \* @param args  
     \*/    
    public static void main(String\[\] args) \{    
        // System.out.println("This is println message.");    
   
        for(int i=0;i<2000;i++) \{  
            // 记录debug级别的信息    
            logger.debug("This is debug message.");    
            // 记录info级别的信息    
            logger.info("This is info message.");    
            // 记录error级别的信息    
            logger.error("This is error message.");    
        \}  
    \}    
   
\}
