一、要点讲解

　　1.引入构建 spring 、spring mvc 的框架类库

　　spring-context：因依赖会自动引入 spring-aop spring-beans spring-core spring-expression 四个包

　　spring-context-support

　　spring-aspects

　　spring-tx

　　jackson-annotations：Jackson 用来解析数据，如json 或者 httpmessage 等

　　jackson-databind

　　jackson-core

　　jackson-dataformat-xml　　

　　mybatis-spring：为了在spring中使用 mybatis orm 的 bean

　　mybatis

　　mysql-connector-java：链接mysql数据库的驱动

　　druid：数据库链接池　　

　　2.在Tomcat中启动 Web 的必要配置

　　web-app：使用 servlet 3.0 的配置

　　context-param：上下文环境配置

　　listener：监听配置

　　servlet：核心 servlet 配置，决定了 spring MVC 框架的启用

　　3.Spring 、Spring MVC 运行相关必要配置

　　mvc:annotation-driven：

　　　　启用spring mvc 注解, 默认的注解映射的支持

　　　　自动注册 RequestMappingHandlerMapping RequestMappingHandlerAdapter 两个 bean，这是 Spring mvc 分发请求所必须的

　　　　并提供了数据绑定支持：读写XML支持、读写Json支持

　　mvc:default-servlet-handler：

　　　　对静态资源文件的访问，

　　　　将无法mapping到Controller的path 交给default servlet handler处理

　　context:annotation-config：

　　　　开启注解处理器

　　context:component-scan：

　　　　自动扫描包，注册 @Controller @Service @Repository @Component 等注解的类成为 bean
