Spring Security不适用于“ hasRole（'ROLE_ADMIN'）”或ROLE_ADMIN

Question

我正在使用Spring
Security版本4.1。如果指定access="hasRole('ROLE_ADMIN')"或access="ROLE_ADMIN"在安全配置中，我可以登录，但无法访问我的管理页面。

<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：

我可能会缺少什么？

我对此有一个小的解释。在这里，您已通过普通用户身份验证，但无权查看管理员页面。

如果您使用的是access="hasRole('ROLE_ADMIN')"表达式，那么Spring
EL类（即SecurityExpressionRoot）将为 ROLE_
我们在hasRole()表达式中提供的每个角色添加前缀。因此，根据您的情况，您提供的角色可以hasRole('ROLE_ADMIN')解决ROLE_ROLE_ADMIN。

因此，您被认证为具有的用户ROLE_ADMIN。但是对于Spring Security框架，要查看管理页面，用户必须具有角色
ROLE_ROLE_ADMIN （因为SecurityExpressionRoot该类添加了ROLE_前缀）。

因此，为此ROLE_在代码中删除该前缀，即在这里access="hasRole('ADMIN')" ，Spring
Security将ROLE_自动添加该前缀。并确保您已将数据库中的管理员角色指定为ROLE_ADMIN。
