我正在尝试使用 JAX-RS 和 Widlfly Swarm（2017.4.0 版本）使用 JAX-RS Bean 验证来实现 REST Web 服务。默认 bean 验证注释按预期工作，但自定义约束定义的注释似乎被忽略了。

我的（简化的）REST 端点看起来像这样

@Path("/myservice")
@Produces({ MediaType.APPLICATION_JSON })
@Consumes({ MediaType.APPLICATION_JSON })
public class MyEndPoint {

   @POST
   @Path("/data")
   public Response data(@CheckDate String date) {
          return Response.ok().build();
   }
}

验证约束的注释看起来像

@Retention(RUNTIME)
@Target({ FIELD, PARAMETER })
@Constraint(validatedBy = CheckDateValidator.class)
public @interface CheckDate {
    String message() default "Bad date format";

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

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

验证器类“CheckDateValidator”

public class CheckDateValidator implements ConstraintValidator<CheckDate, String> {

    public static final String dateFormat = "YYYYMMDD";

    @Override
    public void initialize(CheckDate constraintAnnotation) {
    int i = 0;
    }

    @Override
    public boolean isValid(String value, ConstraintValidatorContext context) {
    return validate(value);
    }

    private boolean validate(String dateString) {
      boolean valid = true;
      SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
      sdf.setLenient(false);
      try {
         sdf.parse(dateString.trim());
      } catch (ParseException e) {
        valid = false;
      }
      return valid;
    }
}

用@Email 默认验证器替换@CheckDate 注释

 @Path("/myservice")
    @Produces({ MediaType.APPLICATION_JSON })
    @Consumes({ MediaType.APPLICATION_JSON })
    public class MyEndPoint {

       @POST
       @Path("/data")
       public Response data(@EmailString date) {
              return Response.ok().build();
       }
    }

应用了电子邮件格式验证，但使用我的自定义约束 @CheckDate 没有应用验证。

我想我已经在 POM 文件中添加了所需的 Wildfly Swarm 分数依赖项

我不知道是否需要做任何额外的配置，或者我是否以错误的方式定义了自定义约束。

任何帮助，将不胜感激
