Spring Get Serialized Names in Exception Handler

In the ExceptionHandler for MethodArgumentNotValidExceptions a way for getting the serialized names of the violated fields is missing. Using MethodArgumentNotValidException.getBindingResult().getAllErrors() ... FieldError.getField() the POJO's name is returned which is not acceptable for the response body in case of different serialized names (Example: photoUrls vs. photo-urls).

Code:

@JsonProperty("photo-urls")
private List<URL> photoUrls;

In this case photoUrls is returned which is the wrong key for the client's request.

Thanks for the suggestion. As with https://github.com/spring-projects/spring-boot/issues/25104, this issue really belongs in Spring Framework. We'll transfer the issue over to them. You can identify enhancements that belong in the Spring Boot project by their code's package. All Spring Boot code is in an org.springframework.boot package or sub-package.

See #26507

I am not sure I get the link with @JsonProperty. This is a Jackson-specific hint and the validation happens on the POJO, not on the content of the JSON object. Besides FieldError is pretty specific.

This seems to me that these are two layers of responsibility that should be separate. Thoughts?
