spring boot简介

1.什么是SpringBoot
Spring Boot是由Pivotal团队提供的全新框架，其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置，
从而使开发人员不再需要定义样板化的配置。通过这种方式，Spring Boot致力于在蓬勃发展的快速应用开发领域（rapid application development）成为领导者。
2.SpringBoot特性
1).创建独立的Spring项目
2).内置Tomcat和Jetty容器
3).提供一个starter POMs来简化Maven配置
4).提供了一系列大型项目中常见的非功能性特性，如安全、指标，健康检测、外部配置等
5).完全没有代码生成和xml配置文件
3.SpringBoot运行环境
Spring Boot最新版可以运行在Java6+的环境下，但是Spring官方建议使用Java8。

4.Servlet 容器

Name	Servlet Version
Tomcat 8.5	3.1
Jetty 9.4	3.1
