如何从Spring中的sequence生成entity字段的部分值？

CREATE SEQUENCE my_sequence START WITH 1 INCREMENT BY 1;

@Entity
@Table(name = "my_table")
public class MyEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "my_sequence_generator")
    @SequenceGenerator(name = "my_sequence_generator", sequenceName = "my_sequence", allocationSize = 1)
    private Long id;

    // 其他字段和方法...
}

@Autowired
private MyEntityRepository myEntityRepository;

public void saveMyEntity() {
    MyEntity entity = new MyEntity();
    // 设置其他字段的值...
    myEntityRepository.save(entity);
}
