SpringBoot 运行原理:容器的思想,先将普通使用的配置项加载入容器,只有在加载相应jar包的情况下,才能将配置书香通过配置文件加载入服务类。
在idea创建SpringBoot项目

entity(或者是domain pjo) 实体类包(po:持久化对象和数据库表子端一一对应,符合javaBean规范的纯java对象
vo:业务之间的数据传递和婆一样仅仅包含数据(可以与表对应) 是抽象出的业务对象。
Bo:是包含多个po的集合 ,通过对象注入。
pojo:没有继承任何类,没有实现任何接口,更没有被其他框架侵入的java对象
javaBean:当一个pojo可序列化,又是一个无参构造函数,使用gettter和setter方法访问属性。(满足反射条件)
interceptor(拦截器) 业务调度,请求转发,传给service处理和接收service层处理
service(服务层)业务处理,具体业务功能的实现。面向业务的功能。
mapper(dao层)接口 面向表数据。
