开源软件介绍:
MyBatis JPA ExtraMyBatis JPA Extra对MyBatis扩展JPA功能 1.基于JPA 2.1的注释简化CUID操作; 2.用Interceptor实现数据库SELECT分页查询; 3.提供mybatis-jpa-extra-spring-boot-starter,简化SpringBoot集成; 1、JavaBean注释简单仅有6个注释 - @Entity
- @Table
- @Column
- @Id
- @GeneratedValue
- @Transient
@GeneratedValue有4中策略 AUTO snowflakeid uuid uuid.hex serial SEQUENCE generator值为数据库序列名 IDENTITY generator无,根据数据库自动生成方式
