Embedded Mapping

Table의 column을 Object로 Mapping할 때 사용한다.

• table:  some_codes
  column: someCodeId | description | code1 | name1 | code2 | name2 | code3 | name3

---

@Entity
@Table(name = "some_codes")
public class SomeCode {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long someCodeId;

    private String description;

    @Embedded
    @AttributeOverrides({
            @AttributeOverride(name = "code", column = @Column(name = "code1")),
            @AttributeOverride(name = "name", column = @Column(name = "name1"))
    })
    private CodeSection someSection1;

    @Embedded
    @AttributeOverrides({
            @AttributeOverride(name = "code", column = @Column(name = "code2")),
            @AttributeOverride(name = "name", column = @Column(name = "name2"))
    })
    private CodeSection someSection2;

    @Embedded
    @AttributeOverrides({
            @AttributeOverride(name = "code", column = @Column(name = "code3")),
            @AttributeOverride(name = "name", column = @Column(name = "name3"))
    })
    private CodeSection someSection3;
}

@Embeddable
public class CodeSection {
    @Basic
    private String code;

    @Basic
    private String name;
}
