• 为什么建议框架源码学习从Mybatis开始 @simple
  • 麻雀虽小, 五脏俱全, 且比Spring轻多了
  • mybatis可以说将装饰器模式，动态代理用到了极致

Configuration --> 类似Spring的容器概念

MappedStatement 映射器 --> 类似Spring的BeanDefinition
一个模板对应一个MappedStatement

// 解析
1) xml --> XMLConfigBuilder
2) annotation --> MapperAnnotationBuilder

SqlSession: SQL模板 + 传参 --> 从数据库获取数据

SqlSession是门面接口, 内部工作委托Executor

// Mapper
代理机制

MapperProxyFactory --> 创建代理

// 缓存

MyBatis一级缓存的生命周期和SqlSession一致

二级缓存

// 插件
