springmvc4之<mvc:exclude-mapping path="" />拦截配置

cvc-complex-type.2.4.a: Invalid content was found starting with element 'mvc:exclude-mapping'. One of '{"http://www.springframework.org/schema/mvc":mapping}' is expected.

在配置springmvc拦截器的时候，一直报上面的错误，刚开始以为是xsd文件或版本不匹配，后来网上找了一下，原来是要先配置<mvc:mapping path=""/> ，再配置<mvc:exclude-mapping path=""/>，如下：

错误方式：

 

<mvc:interceptors>
    <!-- 局部拦截器 -->
    <mvc:interceptor>
        <mvc:exclude-mapping path="/user_login" />
        <mvc:exclude-mapping path="/user_logout" />
        <mvc:mapping path="/**" />
        <bean class="com.itcast.oa.interceptor.MyInterceptor" />
    </mvc:interceptor>
</mvc:interceptors>

 

更改之后的：

 

<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="com.itcast.oa.interceptor.MyInterceptor" />
    </mvc:interceptor>
</mvc:interceptors>

 

由此，问题得到解决。
