Spring Security不能与“hasRole（'ROLE_ADMIN'）”或ROLE_ADMIN一起使用

Question

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>

Below is the debug error:

What could I possibly be missing?

Answer 1

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

If you are using access="hasRole('ROLE_ADMIN')" expression, then the Spring EL class (ie 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 .

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).

So for this remove that ROLE_ prefix in your code, ie 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 .
