1、安装Spring Boot CLI
可以通过下载Spring CLI安装包进行安装
具体的版本安装可以到这里下载
本人使用OSX,演示下如何在OSX下安装,【brew的安装请自行百度】
执行如下命令
brew tap pivotal/tap
得到如下输出,表示执行成功

Tapped 10 formulae (50 files, 37.3KB)
在执行下面命令
brew install springboot
得到如下输出,表示执行成功
==> Installing springboot from pivotal/tap

下面我们来演示一个例子
创建文件hello.groovy
代码内容如下
@RestController
class WebApplication {
@RequestMapping('/')
String home() {
"Hello World! Spring"
}
}
保存后,执行下面命令
spring run hello.groovy
得到如下输出后,表示执行运行成功
$ spring run hello.groovy
