三大框架整合的思路

1、Dao层：

Mybatis的配置文件：SqlMapConfig.xml

不需要配置任何内容，需要有文件头。文件必须存在。

applicationContext-dao.xml：

mybatis整合spring，通过由spring创建数据库连接池，spring管理SqlSessionFactory、mapper代理对象。需要mybatis和spring的整合包。

2、Service层：

applicationContext-service.xml：

所有的service实现类都放到spring容器中管理。并由spring管理事务。

 

3、表现层：

Springmvc框架，由springmvc管理controller。

Springmvc的三大组件。

（1）使用maven管理jar包 （这里面除了ssm框架的jar包之外，其他的可以根据需要选择删除）
