안녕하세요 선생님!

 

검증 강의를 듣고 제 프로젝트에 적용시켜보고 있습니다.

 

제 프로젝트에서 URL필드는 java.net.URI를 임포트에서 사용하고있습니다.

 

하지만 스프링문서에서는 어노테이션을 이용해 URL을 검사할때 주석이 달린 필드의 타입이 String이어야 동작하는 것 같습니다.

제 코드

@URL(message = "URL을 제대로 입력했는지 확인해 주세요.")
private URI uri;

맞게 돌아가는 코드

@URL(message = "URL을 제대로 입력했는지 확인해 주세요.")
private String uri;

 

URI필드에 @URL검증을 도입하면 발생하는 오류

만약 URL검증시 String타입으로만 검증이 가능하다면 java.net.URI 필드를 사용하는 제 도메인을 String타입을 사용하는 필드로 고쳐야 하는 것인가요?

 

만약 제 도메인을 고쳐야 하는 것이라면,

보통 개발을 할때 그러면 Integer나 String, long 등의 타입만 사용하고 java.net.URI 같은 import해 사용하는 타입은 지양해야 하는 것인가요?
