1.有jar包

2.web.xml配置

<context-param>

<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log/log4j.properties</param-value>

</context-param>

<listener>
<listener-class>
org.springframework.web.util.Log4jConfigListener
</listener-class>
</listener>

3.本文是在classpath下新建一个log文件夹，把log4j.properties放里边

log4j.properties具体内容根据需要自己写

ps:

log4j.rootCategory=ERROR,F,CON

log4j.appender.CON=org.apache.log4j.ConsoleAppender
log4j.appender.CON.layout=org.apache.log4j.PatternLayout
log4j.appender.CON.layout.ConversionPattern=%-5p %d{yyyy-MM-dd HH:mm:ss} %c %m%n

log4j.appender.F=org.apache.log4j.RollingFileAppender
log4j.appender.F.File=/root/data/gap41/gap41.log
log4j.appender.F.MaxFileSize=10240KB
log4j.appender.F.layout=org.apache.log4j.PatternLayout
log4j.appender.F.layout.ConversionPattern=%-5p %d{yyyy-MM-dd HH:mm:ss,SSS} %c %m%n
