在最新的Spring Security教程-Spring Security实现访问控制教程中，如果没有授权的用户访问加密的页面，默认的403页面就会展示
在本次教程中，我们教你两种自定义Spring Security 默认的403页面的方法

<http auto-config="true"> <intercept-url pattern="/admin*" access="ROLE_ADMIN" /> <access-denied-handler error-page="404"/> </http> |
第二种方法就是创建一个类并实现AccessDeniedHandler类，重写“handle()”方法，在里面设置你自己的访问逻辑
