[SPRING] 하나의 속성에 매핑되지 않은 최대 절전 모드의 referencedColumnNames
SPRING하나의 속성에 매핑되지 않은 최대 절전 모드의 referencedColumnNames
내 봄 3 웹 응용 프로그램에서 최대 절전 모드 4 사용하여 아래의 예외가 점점 :

아래는 Pojo를 사용하는 POJO 메시지입니다.
@Entity
@Table(name = "MESSAGE")
public class Message {
@Id
@Column(name = "message_id")
private String id;
@Column(name = "message_text", nullable = false)
private String messageText;
/**
* Foreign key for user table
*/
@Id
@OneToOne
@JoinColumn(name = "from_user", nullable = false)
private User fromUser;
/**
* Foreign key for discussion table
*/
@Id
@ManyToOne
@JoinColumn(name = "discussion",referencedColumnName="DISCUSSION_ID", nullable = false)
private Discussion discussion;
public Message() {
id = UUID.randomUUID().toString();
}
public String getMessageText() {
return messageText;
}
public void setMessageText(String messageText) {
this.messageText = messageText;
}
public User getFromUser() {
return fromUser;
}
public void setFromUser(User fromUser) {
this.fromUser = fromUser;
}
public Discussion getDiscussionId() {
return discussion;
}
public void setDiscussionId(Discussion discussion) {
this.discussion = discussion;
}
public String getId() {
return id;
}
}
토론 POJO는 다음과 같습니다.
@Entity
@Table(name = "DISCUSSION")
public class Discussion {
@Id
@Column(name = "DISCUSSION_ID")
private String id;
@Column(name = "TITLE", nullable = false)
private String title;
@Column(name = "CATAGORY", nullable = false)
private String catagory;
@Id
@OneToOne
@JoinColumn(name = "discussionOwner", nullable = false)
private User discussionOwner;
public Discussion() {
id = UUID.randomUUID().toString();
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getCatagory() {
return catagory;
}
public void setCatagory(String catagory) {
this.catagory = catagory;
}
public User getDiscussionOwner() {
return discussionOwner;
}
public void setDiscussionOwner(User discussionOwner) {
this.discussionOwner = discussionOwner;
}
public String getId() {
return id;
}
}
내가 뭘 놓치고 있니? 이 두 엔티티 간의 관계는 토론 엔티티가 많은 메시지를 포함 할 수 있으며 메시지는 하나의 토론에만 속할 수 있다는 것입니다
미리 감사드립니다.

==============================
1.복합 키 조인에 관심이있는 사용자는 다음을 시도하십시오.
복합 키 조인에 관심이있는 사용자는 다음을 시도하십시오.
@JoinColumns({ @JoinColumn(name = "x", referencedColumnName = "x"), @JoinColumn(name = "y", referencedColumnName = "y"), @JoinColumn(name = "z", referencedColumnName = "z") })본질적으로, @ID로 표시된 3 개의 열이있는 경우 JPA는 고유 식별을 위해 3 개의 열이 모두 필요하다고 가정합니다. 즉, 외부 키 쪽에서 적절한 외부 키 참조를 만들기 위해 3 개의 열이 필요합니다.
