1、POM文件
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
</parent>
他的父项目是
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>1.5.9.RELEASE</version>
<relativePath>../../spring-boot-dependencies</relativePath>
</parent>
他来真正管理Spring Boot应用里面的所有依赖版本;是Spring Boot的版本仲裁中心;以后我们导入依赖默认是不需要写版本;(没有在dependencies里面管理的依赖自然需要声明版本号)
2、启动器
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
spring-boot-starter:spring-boot场景启动器;帮我们导入了web模块正常运行所依赖的组件;
Spring Boot将所有的功能场景都抽取出来,做成一个个的starters(启动器),只需要在项目里面引入这些starter相关场景的所有依赖都会导入进来。要用什么功能就导入什么场景的启动器
