JPA主键表生成策略示范

public class Address implements Serializable {

    @Id
    @TableGenerator(name = "add_gen", table = "address_gen", pkColumnName = "pkname", valueColumnName = "idvalue", pkColumnValue = "address_id")
    @GeneratedValue(generator = "add_gen")
    private Long id;
    ......

数据库中表结构：

select * from app.ADDRESS_GEN;
