spring log4j

spring对log4j提供了很好的支持。
web.xml中配置代码如下:

Java代码  

1. <context-param>  
2.         <param-name>webAppRootKey</param-name>  
3.         <param-value>webName.root</param-value>  
4.     </context-param>  
5.     <context-param>  
6.         <param-name>log4jConfigLocation</param-name>  
7.         <param-value>WEB-INF/log4j.properties</param-value>  
8.     </context-param>  
9.     <context-param>  
10.         <param-name>log4jRefreshInterval</param-name>  
11.         <param-value>3000</param-value>  
12.     </context-param>  
13.     <listener>  
14.         <listener-class>  
15.             org.springframework.web.util.Log4jConfigListener  
16.         </listener-class>  
17.     </listener>  

<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:

Java代码  

1. log4j.rootCategory=INFO, stdout , R  
2.   
3. log4j.appender.stdout=org.apache.log4j.ConsoleAppender  
4.   
5. log4j.appender.stdout.layout=org.apache.log4j.PatternLayout  
6.   
7. log4j.appender.stdout.layout.ConversionPattern=%d-[HL] %p %t %c - %m%n  
8.   
9. log4j.appender.R=org.apache.log4j.DailyRollingFileAppender  
10.   
11. log4j.appender.R.File=${webName.root}/WEB-INF/logs/log.log  
12.   
13. log4j.appender.R.layout=org.apache.log4j.PatternLayout  
14.   
15. log4j.appender.R=org.apache.log4j.DailyRollingFileAppender    
16.    
17. log4j.appender.R.DatePattern  ='.'yyyy-MM-dd    
18.   
19. log4j.appender.R.layout.ConversionPattern=%d-[HL] %p %t %c - %m%n  
20.   
21. log4j.logger.org.springframework=DEBUG  
22.   
23. log4j.logger.com.ibatis.db=WARN  
24.   
25. log4j.logger.org.hibernate=DEBUG  
26.   
27. log4j.logger.org.hibernate.ps.PreparedStatementCache=WARN  
28.   
29. log4j.logger.com.myproject=DEBUG  

log4j.rootCategory=INFO, stdout , Rlog4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d-[HL] %p %t %c - %m%nlog4j.appender.R=org.apache.log4j.DailyRollingFileAppenderlog4j.appender.R.File=${webName.root}/WEB-INF/logs/log.loglog4j.appender.R.layout=org.apache.log4j.PatternLayoutlog4j.appender.R=org.apache.log4j.DailyRollingFileAppender   log4j.appender.R.DatePattern  ='.'yyyy-MM-dd  log4j.appender.R.layout.ConversionPattern=%d-[HL] %p %t %c - %m%nlog4j.logger.org.springframework=DEBUGlog4j.logger.com.ibatis.db=WARNlog4j.logger.org.hibernate=DEBUGlog4j.logger.org.hibernate.ps.PreparedStatementCache=WARNlog4j.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。
