Jpa配置Oracle自增序列

1. 创建序列

create sequence DEMO.SEQ_ABC_EFG
nominvalue
nomaxvalue
start with 1
increment by 1
cache 20;

2. 代码添加注解

    @Id
    @Column(name = "ID")
    @GeneratedValue(strategy = GenerationType.SEQUENCE,generator="demo_seq")
    @SequenceGenerator(name="demo_seq", sequenceName="SEQ_ABC_EFG", schema="DEMO", allocationSize = 1)
    private Long id;
