무인도

원인 : jpa의 Entity 클래스에서 @Id를 사용하지 않아 발생

해당되는 테이블은 기본키가 없기 때문에 적용하지 않았으나, jpa 규칙상 Entity에 @Id가 필수이므로 어노테이션을 추가하여 수정했다.

실제 DB상에서 기본키인가 여부는 관계가 없으나, Entity의 @Id 어노테이션으로 인하여 기본키를 지정한 것과 동일한 효과를 갖는다.

VO의 파라미터 변경하여 사용하고 싶어서 @JsonProperty를 사용하려고 gradle에 2.9.8 버전을 추가했는데 org.springframework.beans.factory.BeanCreationException 에러가 났다.

검색해 본 결과(링크) 2.10.0 버전 사용을 추천해 줬고 그래서 해결 했다.
