제네릭이 왜 안되었는지~

왜 제네릭이 안되었는지 이제 알았다. 확실히...

먼저 제네릭이 안되었을때의 하이버네이트와 매핑한 bean을 살펴보면

 @Id
 @GeneratedValue(strategy=GenerationType.AUTO)
 public Integer getUserSeq() {
     return userSeq;
 }

오류난 로그

@Column을 명시하지 않았기에 하이버네이트가 매핑된 이름 그대로 컬럼을 찾는다.
DB의 컬럼명은 USER_SEQ인데.. 만약 DB 컬럼명이 USERSEQ였다면 제네릭이 되었을테지만..

아래처럼 고쳐주었다..

 @Id
 @GeneratedValue(strategy=GenerationType.AUTO)
 @Column(name="USER_SEQ")
 public Integer getUserSeq() {
      return userSeq;
 }

제대로 돌아간 로그 기록..

그러니.. 제네릭이 된다.. 하하하;;;

아.. 볍신 인증했네...
