안녕하세요! 백엔드 개발자가 되고 싶어 김영한님 강의 들으며 공부하는 대학생입니다.

다름이 아니라, 강의를 들으면서

findByUsernameAndAgeGreaterThen

테스트를 진행하다가 발생한 오류를 해결하지 못하고 있습니다ㅠㅠ 요류 내용은 아래에 기재해놓았습니다. 찾아보니까 h2 db를 연결 확인, yml 파일 확인 이라는 답변이 많아서 둘 다 해보았는데 해결이 되지 않습니다. 

 

2번째로 기재한 사진의 버전에 맞게 현재 h2 db 2.1.214 버전을 사용하고 있습니다!

Jpa repository를 이용해 생성한 메서드명의 문제가 좀 있었네요ㅠ 영한님의 다음 강의 진도에서 이 부분을 짚어 설명해주시네요! 좋은 강의 항상 감사드립니다!

Hong님의 프로필 이미지
Hong

public interface MemberRepository extends JpaRepository<Member,Long> {

    List<Member> findByUsernameAndAgeGreaterThan(String username, int age);
}
@Test
 public void findByUsernameAndAgeGreaterThen(){
   Member m1 = new Member("AAA", 10);
   Member m2 = new Member("AAA", 20);
   memberRepository.save(m1);
   memberRepository.save(m2);

   List<Member> result = memberRepository.findByUsernameAndAgeGreaterThan("AAA", 15);

   System.out.println("result = " + result);
   assertThat(result.get(0).getUsername()).isEqualTo("AAA");
   assertThat(result.get(0).getAge()).isEqualTo(20);
   assertThat(result.size()).isEqualTo(1);
    }

Than을 Then으로 명명시 발생하는 오류..?

Then과 Than의 차이에서 발생한 것 같네요. 정민규님 댓글대로 다음 강의 봐야 알 것 같습니다! 

 

-> document에서 애초 Than이라고 명명되어있네요.

안녕하세요. 정민규님

오류 메시지를 보니 H2 문제는 아닌 것 같아요. 다음 메시지를 참고해보시면 오류를 찾으실 수 있을 것 같아요.

study.datajpa.repository.MemberRepository.findByUsernameAndAgeGreaterThen(java.lang.String,int)! No property 'greaterThen' found for type 'int' Traversed path: Member.age

그래도 해결이 안되면

전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.

구글 드라이브 업로드 방법은 다음을 참고해주세요.

주의: 업로드시 링크에 있는 권한 문제 꼭 확인해주세요

 

추가로 다음 내용도 코멘트 부탁드립니다.

1. 실행 방법을 알려주세요.

2. 어떻게 문제를 확인할 수 있는지 자세한 설명을 남겨주세요.

감사합니다.

감사합니다.
