I made a custom response API and am going to send a request with requestDto.

But validation doesn’t work.
Even if an abnormal request is sent, the validity cannot be verified.

    @PostMapping
    public Api<requestDto> requestApi(
        @RequestBody @Valid Api<RequestDto> request) {
        RequestResponse response = testService.testRequest(request.getBody());

        return Api.OK(response);

    }

@Data
@NoArgsConstructor
@AllArgsConstructor
public class RequestDto {


    @NotBlank
    @Size(min = 1, max = 100)
    private String address;

    @NotNull
    private LocalDateTime date;

}

    @PostMapping
    public Api<requestDto> requestApi(
        @RequestBody @Valid Api<RequestDto> request, Errors errors) {
        customApiValidator.validate(request.getBody(), errors);
        RequestResponse response = testService.testRequest(request.getBody());
        
        return Api.OK(response);

    }

@Component
@RequiredArgsConstructor
@Slf4j
public class CustomApiValidator implements Validator {

    private final SpringValidatorAdapter validator;

    @Override
    public boolean supports(Class<?> clazz) {
        return Api.class.isAssignableFrom(clazz);
    }

    @Override
    public void validate(Object target, Errors errors) {
        if (target instanceof Api) {
            Api<?> api = (Api<?>) target;
            Object body = api.getBody();
            validator.validate(body, errors);
        }
    }
}

I made a custom validator and tried to process it, but it doesn’t work either.
How can I verify the validity of Api?
