@NotNull @NotBlank @Valid 在 Spring Boot Rest api 验证中不起作用

Question

@NotNull、@NotEmpty、@NotBlank 注释在我的其余控制器中不起作用。我的要求是限制控制器的流量，当我在没有所需参数的情况下点击控制器时，会出现 400 错误。但是当我将 null 或空标头传递给控制器​​时，我没有收到 400 错误。我的控制器命中了我的处理程序类，这不是预期的行为

下面是我的控制器

@RestController
@RequestMapping("/intelligent-banking")
public class CrossSellOffersRetrievalController {


    @Autowired
    private CrossSellOffersRetrievalHandler crossSellOffersRetrievalHandler;

    @Autowired
    Environment env;

    @GetMapping(value = "/cross-sell-offers/{interactionPoint}", produces = { MediaType.APPLICATION_JSON_VALUE })
    public ResponseEntity<CrossSellOffersRetrievalResponse> getApplicableOffers(
            @RequestHeader(value = "channelId", required = true) @Valid String channelId,
            @RequestHeader(value = "clientId", required = false) String clientId,
            @RequestHeader(value = "actionId", required = true) @NotNull @NotEmpty String actionId,
            @RequestHeader(value = "customerId", required = true) @NotNull @NotBlank String customerId,
            @RequestHeader(value = "cinSuffix", required = true) @NotNull @NotBlank String cinSuffix,
            @RequestHeader(value = "sessionId", required = true) @NotNull @NotBlank String sessionId,
            @RequestHeader(value = "countryCode", required = true) @NotNull @NotBlank String countryCode,
            @PathVariable(value = "interactionPoint", required = true) @NotNull @NotBlank String interactionPoint,
            @RequestParam(value = "numberOfOffers", required = false) Integer numberOfOffers)
            throws CrossSellOffersException {
       try {

                CrossSellOffersRetrievalResponse crossSellOffersResponse = crossSellOffersRetrievalHandler.getCrossSellOffersRetrievalResponse(channelId,
                        customerId, cinSuffix, countryCode, interactionPoint, sessionId, numberOfOffers);
                HttpHeaders httpHeaders = new HttpHeaders();
                httpHeaders.set("CustomerId", customerId);
                return new ResponseEntity<>(crossSellOffersResponse, httpHeaders, HttpStatus.OK);
        } 
        catch (Exception e) {
            LOGGER.error("Inside CrossSellOffersRetrievalController::getApplicableOffers::Exception - Exception occurred at getApplicableOffers: {} ",e.getMessage());
            throw new CrossSellOffersException(Constants.ERROR_CODE, e.getMessage());
        }
    }
}

您需要通过@Validated向控制器添加注释来启用请求参数和路径变量的验证，以便执行验证。
