spring配置log4j

spring对log4j提供了很好的支持。
web.xml中配置代码如下:

<context-param>
		<param-name>webAppRootKey</param-name>
		<param-value>webName.root</param-value>
	</context-param>
	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>WEB-INF/log4j.properties</param-value>
	</context-param>
	<context-param>
		<param-name>log4jRefreshInterval</param-name>
		<param-value>3000</param-value>
	</context-param>
	<listener>
		<listener-class>
			org.springframework.web.util.Log4jConfigListener
		</listener-class>
	</listener>

这里webAppRootKey代表你的项目名
log4j.properties文件放在WEB-INF下
其代码如下:

log4j.rootCategory=INFO, stdout , R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d-[HL] %p %t %c - %m%n

log4j.appender.R=org.apache.log4j.DailyRollingFileAppender

log4j.appender.R.File=${webName.root}/WEB-INF/logs/log.log

log4j.appender.R.layout=org.apache.log4j.PatternLayout

log4j.appender.R=org.apache.log4j.DailyRollingFileAppender  
 
log4j.appender.R.DatePattern  ='.'yyyy-MM-dd  

log4j.appender.R.layout.ConversionPattern=%d-[HL] %p %t %c - %m%n

log4j.logger.org.springframework=DEBUG

log4j.logger.com.ibatis.db=WARN

log4j.logger.org.hibernate=DEBUG

log4j.logger.org.hibernate.ps.PreparedStatementCache=WARN

log4j.logger.com.myproject=DEBUG

log4j.appender.R.File=${webName.root}/WEB-INF/logs/log.log 指日志产生的路径 在 WEB-INF/logs/log.log
该配置是每天产生1个log文件

log4j.logger.org.springframework=DEBUG

log4j.logger.com.ibatis.db=WARN

log4j.logger.org.hibernate=DEBUG

log4j.logger.org.hibernate.ps.PreparedStatementCache=WARN

这里可以更详细的用日志来显示spring hibernate/ibatis 运行情况！可以通过该日志看到每个查询的list中每个对象数据。
