这时候，spring回拦截所有的请求，包括css，js，导致找不到css。js。

解决办法：

在web.xml中加入下面配置：

<servlet-mapping>  
    <servlet-name>default</servlet-name>  
    <url-pattern>*.css</url-pattern>  
</servlet-mapping>  
 
<servlet-mapping>  
    <servlet-name>default</servlet-name>  
    <url-pattern>*.gif</url-pattern>  
</servlet-mapping>  
 
<servlet-mapping>  
    <servlet-name>default</servlet-name>  
    <url-pattern>*.jpg</url-pattern>  
</servlet-mapping>  
 
<servlet-mapping>  
    <servlet-name>default</servlet-name>  
    <url-pattern>*.js</url-pattern>  
</servlet-mapping> 

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.css</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.gif</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.jpg</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>
</servlet-mapping>
