Spring-boot 第一次成功运行

以下是我的一些本机配置信息

IDE编辑环境：

Spring Tool Suite（STS）
下载网站：https://spring.io/tools/sts/all/

java运行环境：

java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

最好为JDK 1.8以上

Maven版本信息

Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-25T03:49:05+08:00)
Maven home: D:\Java Framework tools\apache-maven-3.5.3\bin\..
Java version: 1.8.0_131, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.8.0_131\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

参考手册：

https://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/

实验步骤

1. STS下创建java Application
2. 创建目录结构：

     src/main/java/Example.java

1. 粘贴XML代码
2. 将pom文件粘贴到项目根目录（必须这样做，否则会出下如下错误信息）
