`1简介`

分为Spring SpringMVC Mybatis三部分 ,

[ Spring:替换创建对象的操作,servlet->service ]
[ mybatis:持久化保存数据,控制bean->数据库 ]
[ springMVC :主要是控制请求,交给DispatcherServlet 然后在渲染视图]

`2思路`

1首先是创建环境,创建完了 ,编写对应的bean dao service controller ,当然了推荐使用Mybatis反向生成工具(贼高效方便简单) 不会的看之前的博客 https://blog.csdn.net/weixin_45434902/article/details/109494420 末尾部分

生成完毕样式为:

2开始你的业务,思路(我这里使用mapscanner可以省略dao的实现类

: 2_1 先在service接口里面生命方法

2_2然后在impl里面实现它 (调用dao,dao调用mapper映射)

3在页面里面发送请求,然后在controller里面接收,然后controller调用service方法,service调用dao,dao调用mapper,然后逐层返回给controller,controller再返回给页面

注意:增删改查上面一定要加 事务注解 @Transactional

`3 我常用的依赖:`

`1 pom的`
