springMVC中log4j的配置

步骤：
1.在webcontent/WEB-INF/lib下添加log4j-api-.jar，以及log4j-core-.jar；
2.新建log4j.properties配置文件，写入配置信息

log4j.rootLogger=DEBUG, Consolelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.Target=System.outlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n

3.在web.xml中添加添加配置

<!-- 配置log4j -->    <context-param>      <param-name>log4jConfigLocation</param-name>      <param-value>classpath:log4j.properties</param-value>      </context-param>      <context-param>    <param-name>log4jRefreshInterval</param-name>    <param-value>6000</param-value>    </context-param>    <listener>        <listener-class>        org.springframework.web.util.Log4jConfigListener        </listener-class>    </listener>

4.在代码中使用

1. 导入log4jpackage
2. 使用

import org.apache.log4j.Logger;

private static Logger logger =      Logger.getLogger(ShoppingCartController.class);logger.info("infoMessage");
