总结

Spring框架最为web工程的管理员负责调控各框架之间的结合以及相互调用，其最鲜明的两大特点IOC和AOP，最为其框架的实现基础，实现了对类实例化的控制权反转 ，和项目横向编程的功能。

Spring的配置文件 applicationContext.xml 承载所有的bean负责对bean的初始化和相互依赖，以及对bean生命周期的管理。

SpringMVC 配置文件 applicationContext-mvc.xml 负责管理所有与SpringMVC相关bean，诸如org.springframework.web.servlet.view.InternalResourceViewResolver 上传bean org.springframework.web.multipart.commons.CommonsMultipartResolver

mybatis的配置文件 mybatis-config.xml 负责mybatis 相关参数的初始化工能

mybatis 配置文件 UserMapper.xml 负责负责数据库表的增删改查。

log4j.xml 负责日志文件的配置

dbproperties.properties 数据库连接相关属性的配置
