@Secured函数获取授权用户的拒绝访问权限

Question

我已经按照很多线程将Spring Security实现到我的rest API.最初我被卡在@Secured注释被忽略,现在我已经解决了,我被困在获得拒绝访问.

感觉像我的问题听起来非常相似:@secured与授权的权限抛出访问被拒绝的异常 - 但我仍然被拒绝访问.

这是我的设置:

弹簧security.xml文件

<authentication-manager>
    <authentication-provider user-service-ref="userDetailsService">
        <password-encoder ref="passwordEncoder" />
    </authentication-provider>
</authentication-manager>

<beans:bean id="passwordEncoder" class="org.springframework.security.authentication.encoding.PlaintextPasswordEncoder"/>

<user-service id="userDetailsService">
    <user name="john" password="john1" authorities="ROLE_USER, ROLE_ADMIN" />
    <user name="jane" password="jane1" authorities="ROLE_USER" />
    <user name="apiuser" password="apiuser" authorities="PERMISSION_TEST" />
</user-service>

控制器:

@Controller
@RequestMapping("/secure")
public class SecureController
{
    private static final Logger logger = Logger.getLogger(SecureController.class);

    @Secured("PERMISSION_TEST")
    @RequestMapping(value = "/makeRequest", method = RequestMethod.GET)
    @ResponseBody
    public SimpleDTO executeSecureCall()
    {
        logger.debug("[executeSecureCall] Received request to a secure method");

        SimpleDTO dto = new SimpleDTO();
        dto.setStringVariable("You are authorized!");

        return dto;
    }

}

现在 - 没有正确的

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

我的请求通过(这是因为@Secured注释被忽略).当我把它放入并使用"apiuser"/"apiuser"访问它时,我一直拒绝访问,调试日志:

思考？

提前致谢!

Answer 1

我记得@Secured注释只适用于ROLE_默认开始的角色名称 .

您可以切换到@PreAuthorize("hasAuthority('PERMISSION_TEST')")(使用pre-post-annotations="enabled")或重命名您的角色.

Answer 2

我想再向Michail Nikolaev补充一点.我的答案来自源代码的观点.我希望您了解访问被拒绝的原因.

来自文档:

当您使用命名空间配置时,将自动为您注册AccessDecisionManager的默认实例,并将根据您在intercept-url和protect-pointcut声明中指定的访问属性,为方法调用和Web URL访问做出访问决策. (如果使用注释安全方法,则在注释中).默认策略是使用具有RoleVoter和AuthenticatedVoter的AffirmativeBased AccessDecisionManager.

RoleVoter使用ROLE_前缀(默认情况下)来决定它是否可以投票.您可以使用RoleVoter.setRolePrefix()方法更改该默认前缀.

来自源代码:

public class RoleVoter implements AccessDecisionVoter<Object> {

(...)

private String rolePrefix = "ROLE_";

(...)

public void setRolePrefix(String rolePrefix) {

   this.rolePrefix = rolePrefix;

}

(...)

public boolean supports(ConfigAttribute attribute) {

   if ((attribute.getAttribute() != null) &&
              attribute.getAttribute().startsWith(getRolePrefix())) {
       return true;
   } else {
       return false;
   }
}

(...)

public int vote(Authentication authentication, Object object, 
                       Collection<ConfigAttribute> attributes) {
    int result = ACCESS_ABSTAIN;
    Collection<? extends GrantedAuthority> authorities = 
                                            extractAuthorities(authentication);

    for (ConfigAttribute attribute : attributes) {
        if (this.supports(attribute)) {
            result = ACCESS_DENIED;

            // Attempt to find a matching granted authority
            for (GrantedAuthority authority : authorities) {
                if (attribute.getAttribute().equals(authority.getAuthority())) {
                    return ACCESS_GRANTED;
                }
            }
        }
    }

    return result;
}

PERMISSION_TEST并不是从ROLE_如此RoleVoter弃权决定开始的.AuthenticatedVoter也弃权(因为你没有IS_AUTHENTICATED_在@Secured注释中使用前缀).

最后,投掷的AffirmativeBased实施因为都投了弃权票.AccessDecisionManagerAccessDeniedExceptionAccessDecisionVoters

Java文档AffirmativeBased:

org.springframework.security.access.AccessDecisionManager的简单具体实现,如果任何AccessDecisionVoter返回肯定响应,则授予访问权限.
