spring 中log4j的配置_bea.xml中配置log4j-优快云博客

本文介绍如何在Web应用中配置Log4j进行日志记录。包括在WEB-INF目录下创建log4j.properties文件设置日志级别及输出格式，并在web.xml中注册Log4j配置监听器。同时提供了Maven依赖示例来整合Log4j。

新建文件在WEB INF 下 log4j.properties

log4j.rootLogger=DEBUG, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%5p [%t] (%F:%L) - %m%n

web.xml中添加

<context-param>
       <param-name>log4jConfigLocation</param-name>
       <param-value>/WEB-INF/log4j.properties</param-value>
   </context-param>
   <listener>
       <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
   </listener>
