主键生成注解

[icexmoon]

Hibernate 6.5 开始已经弃用GenericGenerator注解，推荐使用IdGeneratorType：

@IdGeneratorType(com.blinkfox.fenix.id.SnowflakeIdGenerator.class)
@Retention(RetentionPolicy.RUNTIME)
@Target({METHOD, FIELD})
public @interface SnowflakeIdGenerator {
}

实体类：

@Table(name = "tb_book")
@Entity
@Data
@NoArgsConstructor
public class Book {
    @Id
    @SnowflakeIdGenerator
    private Long id;
    @Column(length = 20)
    private String name;

    public Book(String name) {
        this.name = name;
    }
}
