내 데이터베이스 테이블에 대한 모델 클래스를 작성하기 위해 최대 절전 모드 주석을 사용하려고합니다.hibernate4 : 참조하는 외부 키의 컬럼 수가 잘못되었습니다. 2이어야합니다
나는 각각 기본 키 User와 ChartDetails를 가진 두개의 테이블을 가지고있다.
enter code here
package com.winnow.springservice.domain;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
//User Entity class mapped with hibernate
@Entity
@Table(name="User")
@SuppressWarnings(value = { "all" })
public class User implements Serializable
{
@Id
@Column(name="user_id")
public String user_Id;
@Column(name="user_name")
public String userName;
public String password;
@Column(name="last_login")
public String last_Login;
@Column(name="role_id")
public int role_Id;
public int status;
/**
* @return the user_Id
*/
public String getUser_Id() {
return user_Id;
}
/**
* @param user_Id the user_Id to set
*/
public void setUser_Id(String user_Id) {
this.user_Id = user_Id;
}
/**

*/
public String getLast_Login() {
return last_Login;
}
/**
* @param last_Login the last_Login to set
*/
public void setLast_Login(String last_Login) {
this.last_Login = last_Login;
}
/**

*/
public int getRole_Id() {
return role_Id;
}
/**
* @param role_Id the role_Id to set
*/
public void setRole_Id(int role_Id) {
this.role_Id = role_Id;
}
/**

public int getStatus() {
return status;
}
/**

public void setStatus(int status) {
this.status = status;
}
/**

그러나 ChartsStarredBy 테이블에서 이러한 제약 조건을 참조 할 수있는 방법을 찾을 수 없습니다.

}
