ssm整合配置文件

整合思路：
Dao层：
1、SqlMapConfig.xml，空文件即可。需要文件头。
2、applicationContext-dao.xml。
a)数据库连接池
b)SqlSessionFactory对象，需要spring和mybatis整合包下的。
c)配置mapper文件扫描器。

Service层：
1、applicationContext-service.xml包扫描器，扫描@service注解的类。
2、applicationContext-trans.xml配置事务。

Controller层：
Springmvc.xml
1、包扫描器，扫描@Controller注解的类。
2、配置注解驱动。
3、视图解析器

Web.xml
1.配置spring容量监听器
2.配置前端控制器
