복합 키 (EJB)가 포함 된 명명 된 쿼리

Question

복합 키가있는 연관 테이블이 있습니다. 일부 값 (복합 키)을 기반으로 선택하는 명명 된 쿼리를 실행하려고합니다. 내가 이해하는 경우

Answer 1

: 이것은 내가 (JBOSS) 다음을 배포하고 서버를 시작할 때 얻을 첫 번째 오류입니다

@Entity 
@NamedQueries({ 
@NamedQuery(name = "MW.findAll", query = "SELECT mw FROM MemberWorkout mw"), 
@NamedQuery(name = "MW.find1", query = "SELECT mw FROM MemberWorkout mw WHERE mw.SocialSecurity LIKE :SocialSecurity"), }) 
@Table(name = "MemberWorkout") 
public class MemberWorkout implements Serializable { 

private Member member; 
private Workout workout; 
private String date; 
private MWId mwId; 

@EmbeddedId 
public MWId getId() { 
    return mwId; 
} 

public void setId(MWId mwId) { 
    this.mwId = mwId; 
} 
.... 
@ManyToOne 
@JoinColumn(name = "SocialSecurity", insertable = false, updatable = false) 
public Member getMember() { 
    return member; 
} 

public void setMember(Member member) { 
    this.member = member; 
} 

:

이

처럼 코드가 모습입니다 SocialSecurity은 MWId 임베딩 가능 필드입니다. 쿼리에 액세스하려면 다음과 같이 임베디드 ID를 통해 그것을로 이동해야합니다

SELECT mw FROM MemberWorkout mw WHERE mw.id.SocialSecurity... 

을 나는 속성 이름은 당신의 코드와 같이 대문자로 가정하고있다. 그렇지 않은 경우 올바른 이름으로 바꾸십시오.

당신이 접근 방법이 주석이되어 있기 때문에, 당신은 자바 빈즈 표준 (getId()는 HQL과 JPQL이 id로 preperty에 액세스하는 것을 의미한다)에 따라 쿼리에서 속성의 이름을 지정해야한다는 것을 의미 속성 액세스를 사용하고 있습니다 . 필드에 주석을 달 경우 쿼리를 mwId으로 변경해야합니다.
