Spring 配置log4j(轉)

1、在WEB中加入對Spring對log4j的支持：

即在web.xml文件中加入如下代碼：

Java代碼
<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/config/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>

<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/config/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>


注意：這裏webAppRootKey代表你的項目名 。

2、log4j.properties文件放在WEB-INF/config下

配置log4j.properties文件：

Java代碼
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.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


注意：

log4j.appender.R.File=${webName.root}/WEB-INF/logs/log.log 指日誌產生的路徑 在 WEB-INF/logs/log.log
該配置是每天產生1個log文件

Java代碼
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.org.springframework=DEBUG

log4j.logger.com.ibatis.db=WARN

log4j.logger.org.hibernate=DEBUG

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

這裏可以更詳細的用日誌來顯示spring hibernate/ibatis 運行情況！可以通過該日誌看到每個查詢的list中每個對象數據。
