Spring Boot 简介(入门篇)_JAVA教程

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
Undertow 1.3	3.1
