如何限制对 Spring MVC 控制器的访问

Question

我正在编写一个带有授权和注册表的网络服务。有两种类型的用户：普通用户和管理员。有一个控制器在给定的 URL:

发送到管理页面

@Controller
public class ViewPageController {
    @RequestMapping(value = "/admin", method = RequestMethod.GET)
    public String sendAdminPage(){
        return "AdminPage";
    }
}

但是普通用户也可以访问这个页面。只有以管理员身份登录的用户才能进入管理页面。有如何组织的选项？也许在会话中保存登录用户？（最好没有 Spring 安全性）

像这样定义方面和 annotation.some 代码的简单方法

@Inherited
@Target({ElementType.TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface Authorize {

//
String[] value() default {};

}

AuthorizationAspect.java

@Slf4j
@Aspect
@Component
@RequiredArgsConstructor
public class AuthorizationAspect {

private final AuthorizationService authorizationService;

private final CacheUtil cacheUtil;

private static final String PRE = "AUTH";

@Before("@annotation(com.jin.learn.config.security.Authorize)")
public void checkPermission(JoinPoint joinPoint) {
    HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();

    Long accountId = JWTUtil.getUserIdFromRequest(request);
    Set<String> authorization = cacheUtil.getAllSet(PRE + accountId);
    if(authorization==null){
        authorization = authorizationService.findByAccountId(accountId);
        cacheUtil.save(PRE + accountId, authorization);
    }
    Authorize authorize = ((MethodSignature) joinPoint.getSignature()).getMethod().getAnnotation(Authorize.class);
    String[] needAuthorization = authorize.value();
    if (needAuthorization.length == 0)  return;
    if (authorization!=null && !authorization.isEmpty()) {
        if (!authorization.containsAll(Arrays.asList(needAuthorization))){

            throw new SystemException(ExceptionCode.NO_PERMISSION);
        }
    } else {
        throw new SystemException(ExceptionCode.NO_PERMISSION);
    }
 }
}

这样使用

@Authorize(value="needRight")
@RequestMapping(value = "/admin", method = RequestMethod.GET)
public String sendAdminPage(){
    return "AdminPage";
}

此外，还有一些安全框架shiro and spring-security
