1，写个初始化的SERVLET：
package net.welovetennis.util.log;
import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.log4j.*;
/**
*
Title:
*
Description:
*
Copyright: Copyright (c) 2004
*
Company:
* @author not attributable
* @version 1.0
*/
public class Log4jInit extends HttpServlet {
//Initialize global variables
public void init() throws ServletException {
String prefix = getServletContext().getRealPath("/");
String file = getInitParameter("log4j");
// if the log4j-init-file is not set, then no point in trying
System.out.println("................log4j start");
if(file != null) {
PropertyConfigurator.configure(prefix+file);
}
}
//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) {
}
//Clean up resources
public void destroy() {
}
}
2，修改WEB。XML：
log4jinit
net.welovetennis.util.log.Log4jInit
log4j
WEB-INF/log4j.properties
1
3，在WEB-INF下放配制文件log4j.properties，并指定输出路径：
log4j.rootLogger=INFO, A1 , R
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=c:/project/david/racquet/logs/log4j.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
