spring+springmvc+mybatis框架的搭建

总结一下SSM框架的搭建，先给大家说一下整个框架搭建的思路和步骤：

第一步：整合dao层

Mybatis和spring整合，通过spring管理mapper接口。
使用mapper的扫描器自动扫描mapper接口在spring中进行注册。

第二步：整合service层

通过spring管理service接口
使用配置方式将service接口配置在spring配置文件中。
实现事务控制。

第三步：整合springmvc

由于springmvc是spring的模块，不需要整合。

环境准备

Springmvc版本：spring3.2

Mybatis版本：Mybatis3.2.7

jar包：

1.数据库驱动包

2.Mybatis的jar包

3.Mybatis和spring整合包

4.Log4j包

5.数据库连接池包：dbcp包

6.spring3.2的所有jar包

7.jstl包

以下是是项目需要的所有jar包：



这是整个项目的目录：
