springboot+jpa 无法save父类中的属性

Question

1、父类 @Embeddable @Inheritance(strategy = JOINED) public abstract class BaseEntity implements Serializable { private static final long serialVersionUID = 1L; @Column @Temporal(TemporalType.TIMESTAMP) private Date createDate; @Column @Temporal(TemporalType.TIMESTAMP) private Date updateDate; ... //省去get\set } 2、子类 @Entity @Table(name = "user") public class UserEntity extends BaseEntity implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private long id; private String user; private String password; private String role; private String tel; private String mail; ... } 3、Repository接口 @Repository public interface UserRepository extends CrudRepository<UserEntity , Long> { public UserEntity save(UserEntity user); } `` 4、controller中调用save方法的时候， user.setCreateDate(new Date()); 这个方法最终并没有被save进去，不知打为何 下面是springboot打印的日子 Hibernate: insert into user (mail, password, role, tel, user) values (?, ?, ?, ?, ?)com.example.demo.entity.UserEntity@78730d83 可以看到里面并没有createDate
