三大框架整合的思路

 整合思路

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、Dao层:

7.重新运行cnki-manager

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)
