Question

springmvc的拦截器，怎么设置不拦截的url

Answer 1

<mvc:interceptors>  
    <!-- 局部拦截器 -->  
    <mvc:interceptor>  
        <mvc:mapping path="/**" />                      
        <mvc:exclude-mapping path="/user_login" />  
        <mvc:exclude-mapping path="/user_logout" />  
        <bean class="自动以拦截器实现（如权限拦截器等实现）" />  
    </mvc:interceptor>  
</mvc:interceptors>

exclude-mapping即是需要排除拦截的URL

Answer 2

//exclude-mapping 里的path就是拦截器放过的路径
<mvc:interceptor>
     <mvc:mapping path="/**"/>
     <mvc:exclude-mapping path="/login/*"/>
     <mvc:exclude-mapping path="/login/changeImage.do"/>
     <bean class="interceptor.LoginInterceptor"/>
</mvc:interceptor>
