spring-mvc.xml
需要实现基本功能的配置
- 配置
- 配置
- 配置视图解析器
mvc:annotation-driver/ 相当于注册了DefaultAnnotationHandlerMapping(映射器)和AnnotationMethodHandlerAdapter(适配器)两个bean.即解决了@Controller注解的使用前提配置。
context:component-scan 对指定的包进行扫描，实现注释驱动Bean定义，同时将bean自动注入容器中使用。即解决了@Controller标识的类的bean的注入和使用。

需要实现基本功能的配置
- 配置
- 加载数据资源属性文件
- 配置数据源 三种数据源的配置方式 http://blog.csdn.net/yangyz_love/article/details/8199207
- 配置sessionfactory
- 装配Dao接口
- 声明式事务管理
- 注解事务切面

log4j.properties(配置的日志文件)
# 定义 log 的输出级别
log4j.rootCategory=debug, stdout , R
