JPA中为Entity添加自定义类

 使用@Embeddable和@Embedded注解实现

效果是在tb_test_person中,Address类的字段解析成表字段。

import javax.persistence.*;

@Entity(name = "tb_test_person")
public class PersonEntity {

    @Column(name = "ID_")
    @Id
    @GeneratedValue(strategy=GenerationType.SEQUENCE)
    private Integer id;


    @Column(name ="NAME_")
    private String name;

    @Column(name = "CITY_")
    private String city;

    @Embedded
    private Address address;

}
           

@Data
@Embeddable
public class Address {
    private String zipCode;
}
