我正在努力在两个具有Embeddable Id的类之间建立投标关系。
该关系在两个嵌入式ID的同一列中
基本结构如下:
@Entity
@Table(name="PERSON)
public class Person implements Serializable{
@EmbeddedId
private PersonId entityb;
@Column(name = "firstname")
private String firstname;
@Column(name = "lastname")
private String lastname;
@OneToOne
@JoinColumns({
@JoinColumn(name = "code", referencedColumnName = "code", updatable = false),
@JoinColumn(name = "num", referencedColumnName = "num", updatable = false) })
private Home home;
// Setters Getters.....
}
@Embeddable
public class PersonId implements Serializable{
@Column(name = "code")
private Integer code;
@Column(name = "num")
private Integer num;
// Setters Getters.....
}
@Entity
@Table(name="HOME)
public class Home implements Serializable{
@EmbeddedId
private HomeId entityb;
@Column(name = "name")
private String name;
@Column(name = "adresse")
private String adresse;
// Setters Getters.....
}
@Embeddable
public class HomeId implements Serializable{
@Column(name = "code")
private Integer code;
@Column(name = "num")
private Integer num;
// Setters Getters.....
}
由于两个ID是手动分配的,因此我看不到映射实体上的错误?。
当我调用DAO并通过@Query(value =“ select Person p''中的p)从Person实体获取所有行时,出现“ ReseltSet”错误
