 SSM:(Spring +SpringMVC+MyBatis缩写)是个框架集合,由Spring 、SpringMVC、MyBatis三个开源框架整合而成

spring的作用:spring相当与起一个统领的地位,它将各层进行整合。作用分别为:

  • 管理持久层的dao
  • 管理业务层service,管理事务,service中可调用mapper接口
  • 管理表示层的controller。controller中可调用service几口

      dao,service,controller都是JavaBean,都要加到spring容器中,但其中一点是springMVC本来就是spring的一部分,所以不能用整合这个词来形容

项目结构如下:
