java - 怎么判断自定义注解里的值是否正确？

问题描述

@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个@RateLimit里面各有参数限制，日时分，要避免人为写错参数，怎么加一个判断或者验证，判断它们的参数和正确的顺序匹配？

问题解答

java 8 已经支持多个相同 Annotation 了，判断起来更方便。
