validation in JsonView and grouping of interfaces in @JsonView

Question

I have created DTO , which is having fields, associated with different jsonview, so that only those vields are there in RequestBody and ResponseBody DTO. Below is the sample code:

public class Test {

    @JsonView({
          //Request Views
          CustomerPutOpsRequestBody.class,
          CustomerGetOpsRequestBody.class,
          CustomerQueryPutOpsRequestBody.class,
          
    
          //Response views
          CustomerGetOpsResponseBody.class,
          CustomerPutOpsResponseBody.class,
          CustomerQueryPutOpsResponseBody.class,
          CustomerDeleteOpsResponseBody.class,
          
        })
    @NotBlank(message = "faqId cannot be null or empty",
       groups = {
          //Request Views
          CustomerPutOpsRequestBody.class,
          CustomerGetOpsRequestBody.class,
          CustomerQueryPutOpsRequestBody.class,
        })
        private String faqId;
        .
        .
    
    }

My controller looks something like below:

  @JsonView({CustomerPutOpsResponseBody.class})
      @PostMapping("/v1/faq/update")
      public ResponseEntity<Test> createCustomer(@RequestBody
       @JsonView({CustomerPutOpsRequestBody.class})
       @Validated(CustomerPutOpsRequestBody.class) Test test) {
        //Do something
      }

I am facing 2 problems :

1. @NotBlank validation triggers , even when faqId is not the part of view of RequestDTO. I came across Grouping in validators,that too not working.

2. interface list in @JsonView({..}) , keeps on growing , so is there is any alternative approach to put all interface in some other file and refer that inside @JsonView({<some reference for all interfaces> }) so as to keep things clean
