Spring Security 不适用于“hasRole('ROLE_ADMIN')"；或 ROLE_ADMIN [英] Spring Security does not work with "hasRole('ROLE_ADMIN')" or ROLE_ADMIN

问题描述

我使用的是 Spring Security 4.1 版.如果我在安全配置中指定 access="hasRole('ROLE_ADMIN')" 或 access="ROLE_ADMIN" ，我可以登录，但我无法访问我的管理页面.

I am using Spring Security version 4.1. If I specify access="hasRole('ROLE_ADMIN')" or access="ROLE_ADMIN" in the security configuration, I am able to login, but I am unable to access my admin page.

<security:http use-expressions="true">
    <security:intercept-url pattern="/admin/**" access="hasRole('ROLE_ADMIN')" />
    <!-- security:intercept-url pattern="/admin" access="hasRole('ROLE_ADMIN')" / -->
    <security:intercept-url pattern="/createmanufsensors" access="isAuthenticated()" />
</security:http>
<security:global-method-security secured-annotations="enabled"></security:global-method-security>

下面是调试错误:

我可能遗漏了什么?

推荐答案

对此我有一个小小的解释.在这里，您被认证为普通用户，但无权查看管理页面.

I have a small explanation for this. Here you are authenticated as a normal user but not authorized to view the admin page.

如果您使用的是access="hasRole('ROLE_ADMIN')" 表达式，那么Spring EL 类(即SecurityExpressionRoot)将添加前缀ROLE_ 到每个角色我们在 hasRole() 表达式中提供的.因此，在您的情况下，您在 hasRole('ROLE_ADMIN') 中提供的角色解析为 ROLE_ROLE_ADMIN.

If you are using access="hasRole('ROLE_ADMIN')" expression, then the Spring EL class (i.e SecurityExpressionRoot) will add the prefix ROLE_ to every role that we have provide in hasRole() expression. So in your case the role you have provided in hasRole('ROLE_ADMIN') resolves to ROLE_ROLE_ADMIN.

这就是为什么您被认证为具有 ROLE_ADMIN 的用户.但是到Spring Security框架查看admin页面的用户必须有角色ROLE_ROLE_ADMIN(因为SecurityExpressionRoot 类添加了ROLE_ 前缀).

Thats why you are authenticated as a user who has ROLE_ADMIN. But to the Spring Security framework to view the admin page the user must have the role of ROLE_ROLE_ADMIN (because the SecurityExpressionRoot class added ROLE_ prefix).

因此，为此删除代码中的 ROLE_ 前缀，即这里 access="hasRole('ADMIN')"因此，Spring Security 将自动添加该 ROLE_ 前缀.并确保您已将数据库中的管理员角色指定为 ROLE_ADMIN.

So for this remove that ROLE_ prefix in your code, i.e here access="hasRole('ADMIN')" So, Spring Security will add that ROLE_ prefix automatically. And make sure that you have specified your admin role in database as ROLE_ADMIN.
