Question

我已经遵循了很多线程来为我的rest API实现Spring Security。最初我被卡在@Secured注释被忽略了，现在我已经解决了，我被困在拒绝访问。

感觉我的问题听起来非常类似于：@secured with granted authorities throws access denied exception - 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：

11:42:43,909 [http-apr-8080-exec-4] DEBUG DispatcherServlet - Could not complete request

思想？

提前致谢！

Answer 1

我记得@Secured注释仅适用于默认情况下以ROLE_开头的角色名称。

您可以切换为@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。我希望你理解访问被拒绝的原因。

来自文档：

当您使用命名空间配置时，会自动为您注册一个默认的AccessDecisionManager实例，并将根据您在拦截网址中指定的访问属性，使用它来为方法调用和Web URL访问做出访问决策。 -pointcut声明（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）以决定是否可以投票。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不以ROLE_开头，因此RoleVoter弃权决定。 AuthenticatedVoter也弃权（因为您未在IS_AUTHENTICATED_注释中使用@Secured前缀。

最后，AffirmativeBased AccessDecisionManager的实施引发了AccessDeniedException，因为AccessDecisionVoters都弃权了。

AffirmativeBased的Java文档：

简单的具体实现授予的org.springframework.security.access.AccessDecisionManager 访问，如果任何AccessDecisionVoter返回肯定响应。

@Secured函数获取授权用户的拒绝访问权限
