本文详细介绍了创建第一个基于eclipse（eclipse-jee-neon-3-win32-x86\_64.zip）+spring boot创建的项目。

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，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。也就是说，Spring Boot是为了简化Spring开发而生，主要思想是降低spring的入门，使得新手可以以最快的速度让程序在spring框架下跑起来。

今天我们就来创建第一个基于eclipse（eclipse-jee-neon-3-win32-x86\_64.zip）+spring boot创建的项目。

一、安装STS插件

要在eclipse使用spring boot创建项目，必须先安装STS（Spring Tool Suite (STS) for Eclipse），如果网速给力的话可以选择在线安装，否则建议选择离线安装。

1.在线安装

Help -> Eclipse Marketplace

Search或选择“Popular”标签，选择Spring Tool Suite (STS) for Eclipse插件，安装：

2. 离线安装

（1）先下载STS插件，下载地址为：[https://spring.io/tools/sts][https_spring.io_tools_sts]

（2）Help->Install New Software

（3）点击"Add->Archive.."，然后选择刚才下载的STS插件，并给插件起个名字,点击"OK"就行了。

（4）选择几个以IDE结尾的组件安装就可以了，如果等待的事件较久，可以一个一个安装。

（5）查看是否安装成功

Window->Show View->Other，查看是否有Spring组件，有则表明我们已经安装成功了。

二、创建Spring Boot项目

（1）创建项目，选择Spring starter Project。填写跟项目相关的各种信息，然后Next：

（2）选择需要的Dependency，然后Next：

（3）最后"Finish",就开始下载jar包了，这个过程需要的时间比较长。

三、运行项目

（1）右键DemoApplication中的main方法，Run As -> Spring Boot App，项目就可以启动了。

（2）如果要运行hello world，则使用@RestController注解，并且添加hello方法。

如何运行我们的Application，看到hello world的输出呢？

第一种方式是直接运行main方法：

选中DemoApplication的main方法 -> 右键 -> Run as ->Java Applicacation，之后打开浏览器输入地址：http://127.0.0.1:8080/就可以看到Hello world!了。

第二种方式：

右键project –> Run as –> Maven build –> 在Goals里输入spring-boot:run ,然后Apply,最后点击Run。

四、打包

1.命令：clean package

2. 执行命令：Java –jar xxxxxx.jar
