log4j+SpringMVC的配置 博客分类： JAVAjava的开源框架Spring和SpringMVC log4jspringMVC

1 搭建起springMVC的环境
2 web.xml的配置

 <!-- 设置根目录 默认值 webapp.root -->  
   <context-param>    
       <param-name>webAppRootKey</param-name>    
       <param-value>webapp.root</param-value>    
   </context-param>    

<!-- 默认位于classpath:/log4j.properties -->
   <context-param>  
    <param-name>log4jConfigLocation</param-name>  
    <param-value>/WEB-INF/classes/log4j.properties</param-value>  
</context-param>  
<!-- 3000表示 开一条watchdog线程每60秒扫描一下配置文件的变化;这样便于日志存放位置的改变 -->  
<context-param>    
        <param-name>log4jRefreshInterval</param-name>    
        <param-value>3000</param-value>    
   </context-param>  
<!-- 必须配置的 只有配置了这个操作系统中才会生成真正的文件--> 
<listener>  
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>  
</listener>

整个内容如下：
