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
