spring mvc3截拦器如何截拦静态文件

Question

请问我要截拦ROOT下某个目录下面的静态文件如test.txt应该怎么配置？ 
http://localhost:8080/upload/test.txt 
截拦这种访问 

我这样子配置不行： 

<mvc:interceptors>
    <bean class="com.my.filter.FileInterceptor" />
	<mvc:interceptor>
		<mvc:mapping path="/**" />
		<!-- 
		<mvc:mapping path="/*.do" />
		 -->
		<bean class="com.my.filter.LoginInterceptor" />
	</mvc:interceptor>
</mvc:interceptors>

Answer 1

可以在Tomcat端拦截,在 web.xml 里添加 

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

<mvc:interceptors>   
        <mvc:interceptor>   
            <mvc:mapping path="*.txt" />   
            <bean class="com.my.filter.LoginInterceptor" />   
        </mvc:interceptor> 
         <mvc:interceptor>   
            <mvc:mapping path="/**" />   
            <!--    
            <mvc:mapping path="/*.do" />   
             -->   
            <bean class="com.my.filter.LoginInterceptor" />
