我已经跟踪了很多线程来为我的 rest API 实现 Spring Security。最初我被@Secured注释被忽略，现在我已经解决了，我被困在被拒绝访问。

感觉我的问题听起来非常类似于：@secured with grant authoritys throws access denied exceptions - 但我仍然被拒绝访问。

这是我的设置：

弹簧安全.xml 

<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 -没有适当的

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

我的请求通过了（这是因为 @Secured 注释被忽略了）。当我将它放入并使用“apiuser”/“apiuser”访问它时，我一直被拒绝访问，调试日志：

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

想法？

我记得@Secured注释仅适用 ROLE_于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。

我想在 Michail Nikolaev 的回答中添加更多内容。我的回答是从源代码的角度。我希望您了解访问被拒绝的原因。

从文档：

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，并将用于根据您在拦截 URL 和保护切入点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（如果您使用注释安全方法，则在注释中）。默认策略是使用带有 RoleVoter 和 AuthenticatedVoter 的 AffirmativeBased AccessDecisionManager。

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

从源代码：

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没有开始，ROLE_所以RoleVoter放弃决定。AuthenticatedVoter也弃权（因为您没有在注释中使用IS_AUTHENTICATED_前缀）。@Secured

最后，由于双方都投了弃权票，因此AffirmativeBased执行了AccessDecisionManagerthrows 。AccessDeniedExceptionAccessDecisionVoters

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。
