如何在Spring自定义验证器中获取应用于字段的当前验证约束组？

Question

我有一个条件，希望基于其他字段值有条件地应用一些验证。我已经为此创建了组约束，但是我不确定如何在自定义验证器类中使用这些约束组。我的约束组可以很好地用于诸如NOTNULL之类的预定义验证，但是我希望我的自定义验证器也仅在指定的组适用时才被调用。

我已经检查了api文档，但是找不到任何方法来获取当前适用的约束组。

static_assert( true  == is_tpl_same<std::set, std::set>::value, "!" );
static_assert( false == is_tpl_same<std::vector, std::set>::value, "!" );

@RestController
@Slf4j
public class QuoteDetailController {

  private QuoteDetailService applicationService;

  @Autowired
  public QuoteDetailController(QuoteDetailService applicationService) {
    this.applicationService = applicationService;
  }

    @PostMapping(value = "/quote/retail")
    public ResponseEntity<String> saveQuoteForRetail(
      @RequestBody @Validated(value = RetailCustomerConstraintGroup.class) QuoteDetail quoteDetail) {
    log.info("Request for saveQuote in controller : {}", quoteDetail);
    String response = applicationService.saveQuote(quoteDetail);
    log.info(response);
    return ResponseEntity.ok(response);
    }

    @PostMapping(value = "/quote/corporate")
    public ResponseEntity<String> saveQuoteForCorporate(
      @RequestBody @Validated(value = CorporateCustomerConstraintGroup.class) QuoteDetail quoteDetail) {
    log.info("Request for saveQuote in controller : {}", quoteDetail);
    String response = applicationService.saveQuote(quoteDetail);
    log.info(response);
    return ResponseEntity.ok(response);
    }
}

public class QuoteDetail {

  private Long Id;
  private Double price;
  private String description;
  private String customerType;
  @ValidCustomer(groups= {RetailCustomerConstraintGroup.class,CorporateCustomerConstraintGroup.class})
  private CustomerDetails customerDetails;
  @NotNull(groups= CorporateCustomerConstraintGroup.class)
  private ContactPersonDetail contactPersonDetail;
}

@Documented
@Constraint(validatedBy = {CustomerDetailValidator.class})
@Target({ElementType.METHOD, ElementType.FIELD, ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
public @interface ValidCustomer {

  public abstract String message() default "Invalid value.";

  public abstract Class<?>[] groups() default {};

  public abstract Class<? extends Payload>[] payload() default {};

  public abstract boolean ignoreCase() default true;
