您可以在实体类中使用以下标记

@Entity
@Table(name = "schools")
class School {
  @Id
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "school_id_seq")
  @SequenceGenerator(name = "school_id_seq", sequenceName = "school_id_seq",  allocationSize=1)
  @Column(name = "id")
  Integer id;
  String name;
  String postcode;
}

Application.properties （政策可以更改）

spring.jpa.hibernate.ddl-auto" : update

这将在应用程序启动时生成以下DDL：

CREATE SEQUENCE IF NOT EXISTS school_id_seq START WITH 1 INCREMENT BY 1;

CREATE TABLE schools
(
    id       INTEGER NOT NULL,
    name     VARCHAR(255),
    postcode VARCHAR(255),
    CONSTRAINT pk_schools PRIMARY KEY (id)
);
