MyBatis
0半自动 ORM 框架，SQL 与 Java 对象映射
核心组件
SqlSessionFactory

创建 SqlSession 的工厂

SqlSession
执行 SQL 的会话
Mapper
接口绑定的 SQL 语句

Configuration

缺点=
SQL 与代码耦合?
数据库迁移成本高A
需要手写 SQLC
适用场景E
1复杂查询、性能要求高、DBA 参与项目G

JPA/HibernateI

数据库无关M
开发效率高O
复杂查询困难Q
性能调优复杂S
学习曲线陡U
/标准 CRUD、快速开发、领域驱动设计W
建议Y
:小型项目用 JPA，大型/复杂查询项目用 MyBatis[
