PostgreSQL的一个实体的多个Hibernate序列生成器

你不能。该生成器仅适用于标识符列。

确保使用脚本（例如

hibernate.hbm2ddl.import_files

create sequence subscription_pre_1_seq start 1 increment 7

然后使用如下映射：

@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="pre",        nullable=false,        unique=true,        insertable = false,        updatable = false,        columnDefinition = "BIGINT DEFAULT nextval('subscription_pre_1_seq')")@Generated(GenerationTime.INSERT)private Integer pre;
