spring mvc 配置 log4j

spring mvc 配置 log4j

spring mvc 配置 log4j 注意事项：

1). 如果 log4j.properties 在 src 目录，则不需要配置 Log4jConfigListener。

2). 如果 log4j.properties 不在 src 目录下，则需要配置 Log4jConfigListener。

具体代码如下：

1). controller 层代码如下:

package com.test.controller;

import javax.servlet.http.HttpServletRequest;

import org.apache.log4j.Logger;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

@RequestMapping(“/hello”)

@Controller

public class Log4jController {

private static Logger logger = Logger.getLogger(Log4jController.class);

@RequestMapping("/hello")
public ModelAndView log4j(HttpServletRequest request){
ModelAndView model = new ModelAndView("hello");
model.addObject("msg", "this is log4j record...");
logger.info("my first log for java ...");
return model;
}

}

log4j.properties 内容如下：

# Set root logger level to DEBUG and its appender to A1 and file.
log4j.rootLogger=DEBUG, file, A1
log4j.category.org.springframework = warn
# file is set to a DailyRollingFileAppender
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=test.log
log4j.appender.file.Append=true
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[test] [%d{yyyy-mm-dd HH:MM:ss}] [%-5p] %l - %m%n
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=[test] [%d{yyyy-mm-dd HH:MM:ss}] [%-5p] %l - %m%n
