我可以为一个实体使用多个序列生成器吗？

@Id
@SequenceGenerator(name=”subscription_id_seq”,sequenceName=”subscription_id_seq”, allocationSize=7)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator=”subscription_id_seq”)
@Column(unique=true, nullable=false)
private Integer id

@Column(name="code", nullable=false, unique=true )
@SequenceGenerator(name="subscription_code_1_seq",sequenceName="subscription_code_1_seq", allocationSize=7)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="subscription_code_1_seq")
private Integer code;
