java - 怎么判斷自定義注解里的值是否正確？

問題描述

@RestController@RequestMapping('/api')public class CasApiController { private final transient Logger logger = LoggerFactory.getLogger(getClass()); private UpTokenServiceInterface upTokenServiceInterface; private static final String LIMITER_KEY = 'CasApiControllerControllerLimiter'; private static final String LIMITER_KEY_HOUR = 'CasApiControllerControllerLimiterHour'; private static final String LIMITER_KEY_DAY = 'CasApiControllerControllerLimiterDay'; private static final int LIMITER_NUM_REQUESTS = 5; private static final int LIMITER_NUM_REQUESTS_HOUR = 10; private static final int LIMITER_NUM_REQUESTS_DAY = 20; @Autowired public CasApiController(UpTokenServiceInterface upTokenServiceInterface) {this.upTokenServiceInterface = upTokenServiceInterface; } @RequestMapping(value = 'qiniu/uptoken', method = RequestMethod.GET ) @ResponseBody @ApiControllerWithArgHttpServletRequestRateLimiterThrottleable @RateLimit(numRequests = LIMITER_NUM_REQUESTS, key = LIMITER_KEY) @RateLimit2(numRequests = LIMITER_NUM_REQUESTS_HOUR, key = LIMITER_KEY_HOUR) @RateLimit3(numRequests = LIMITER_NUM_REQUESTS_DAY, key = LIMITER_KEY_DAY) public JSONObject getUpToken() {JSONObject jsonObject = new JSONObject();jsonObject.put('uptoken',upTokenServiceInterface.uploadToken());return jsonObject; }}-----------------------------3個@RateLimit里面各有參數限制，日時分，要避免人為寫錯參數，怎么加一個判斷或者驗證，判斷它們的參數和正確的順序匹配？

問題解答

java 8 已經支持多個相同 Annotation 了，判斷起來更方便。
