Spring Boot是一个简化了Spring开发的框架。
优点：
1.可以生成独立的微服务功能单元

每一个模块都是可以独立运行的，不过我一般都是有需要的时候才这么做，没必要的话还是放在一个模块里方便。
2.使用内嵌式的Tomcat运行，无需配置Tomcat。
3.starters自动依赖与版本控制
4.大部分配置Springboot已经自动帮我们配置好了，无需写大量的xml配置的文件
一. 搭建Spring Boot
1.File - new - Project

2.快速搭建一个Spring boot

3.设置g a v

4.先简单的依赖mysql，以后如果再有需要的直接在pom.xml中依赖就好

5.项目地址

6.配置maven
1）.如果用系统自带的maven无需更改什么

2.换成自己的maven 注意最后要Apply一下

如此,算是搭建好了一个非常简单的spring boot 项目。
