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
