java - @PreAuthorize 无效。可能是什么问题？

Question

有一个管理页面，我在其中使用了 @PreAuthorize 角色 ROLE_ADMIN 注释，但是没有此角色的用户也可以访问此页面。

这个安全上下文文件

<?xml version="1.0" encoding="UTF-8"?>

    <security:remember-me key="webapp-key" />
    <security:expression-handler ref="expressionHandler" />
</security:http>


<bean id="daoAuthenticationProvider"
    class="org.springframework.security.authentication.dao.DaoAuthenticationProvider">
    <property name="userDetailsService" ref="userDetailsService"></property>
</bean>

<bean class="org.springframework.security.authentication.ProviderManager">
    <constructor-arg>
        <list>
            <ref bean="daoAuthenticationProvider" />
        </list>
    </constructor-arg>
</bean>


<security:authentication-manager>
    <security:authentication-provider
        user-service-ref="userDetailsService">
        <security:password-encoder hash="md5"></security:password-encoder>
    </security:authentication-provider>
</security:authentication-manager>

</beans>

Controller 是:

@Controller
@RequestMapping("/admin")
public class AdminController {

@PreAuthorize("hasRole('ROLE_ADMIN')")
@RequestMapping
public String showAdminPage(){
    return "adminPage";
}
}

编辑:

flag

我添加了代码来检查用户和授予的权限，然后将它们打印出来。这是输出

*************************************** [ROLE_USER] uddeshya *************************************** for 

System.out.println("***************************************\n\n\n");  
System.out.println(SecurityContextHolder.getContext() 
.getAuthentication().getAuthorities()); 
System.out.println(principal.getName()); System.out.println("\n
\n\n***************************************");

要在 Spring MVC Controller 中使用基于注解的方法安全性，您需要在 DispatcherServlet 的上下文配置文件中设置以下内容。

<security:global-method-security
    pre-post-annotations="enabled" secured-annotations="enabled" />

看来你把它放在了不同的配置文件中。
