SprinBoot CLI 安装(Mac版)

1. 安装 HomeBrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. 使用Homebrew安装Spring Boot CLI

2.1 引入 Pivotal 的 tap

$ brew tap pivotal/tap

备注:tap是向Homebrew添加额外仓库的一种途径,Pivotal是Spring及Spring Boot背后的公司;

2.2 安装 Spring Boot CLI

$ brew install springboot

3. 应用

3.1 一个基于Groovy的Spring应用

// HelloController.groovy

@RestController

class HelloController{

    @RequestMapping("/")

    def hello(){

        return "Hello World"

    }

}

3.2 运行

$ spring run HelloController.groovy

3.3 出现问题 "Spring was unable to locate the root of your project. There was no Gemfile present in the current directory"

这是由于Ruby Gem中也有一个叫可执行的spring程序

3.4 解决方案－－环境配置

iTerm2使用的是ZSH
sudo vi ~/.zshrc
查找安装的Spring Boot CLI 路径,并在zshrc文件中写入如下内容:
- export SPRING_HOME="/usr/local/Cellar/springboot/2.0.2.RELEASE"
- export PATH=$SPRING_HOME/bin:$PATH
source ~/.zshrc,更新配置文件
输入 spring --version
- 输出Spirng CLI v2.0.2.RELEASE表明更改成功
