Spring Controller层记录日志配置二

接上文，我的小伙伴配置后不好使，原来当配置了mvc的配置

<mvc:annotation-driven/>
<mvc:default-servlet-handler/>

配置这两行的时候上个配置就不起作用了

所以重新写了文件，记录controller的日志，比上个文章配置更简单。代码可能比较长但是，copy配置下就ok，方便操作

 

配置xml：

 

<beanclass="com.ruishenh.spring.test.MyModelAndViewResolver"id="myModelAndViewResolver"/>

 

 

把下面的类写到自己的代码里

package com.ruishenh.spring.test;
