一、首先导入包

log4j-1.2.11.jar

slf4j-api-1.4.3.jar

slf4j-log4j12-1.4.3.jar

二、web.xml配置

<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>

三、log4j.properties配置

### set log levels ###
log4j.rootLogger = DEBUG , C , D , E

# MyBatis logging configuration...
log4j.logger.com.quicksure.mobile.dao=DEBUG

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender

log4j.appender.C.layout.ConversionPattern = [quicksureMobile][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###

log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [quicksureMobile][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
