 自定义拦截器实现权限验证

实现一个权限验证拦截器。

1. 修改web.xml文件中请求路径

2. 将所有的页面放入WEB-INF目录下

3. 开发登录action

4. 开发拦截器

5. 配置springmvc.xml文件

<!--注册拦截器-->\
<mvc:interceptors>\
    <mvc:interceptor>\
        <!--配置拦截的路径(哪些请求被拦截)-->\
        <mvc:mapping path="/**"/>\
        <!--设置放行的请求-->\
        <mvc:exclude-mapping path="/login"></mvc:exclude-mapping>\
        <mvc:exclude-mapping path="/showLogin"></mvc:exclude-mapping>\
        <!--设置进行功能处理的拦截器类-->\
        <bean class="com.bjpowernode.interceptor.LoginInterceptor"></bean>\
    </mvc:interceptor>\
</mvc:interceptors>
