heroku 部署 Spring Boot 项目

首先创建一个空的 Spring Boot 项目，修改启动类SpringBootHerokuApplication如下

package io.arukas;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
public class SpringBootHerokuApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootHerokuApplication.class, args);
    }

    @GetMapping("")
    public String welcome() {
        return "hello heroku";
    }

}

接下来就可以通过git将代码推送到 Heroku 部署了，前提需要安装 Heroku 客户端，可参考官方文档安装https://devcenter.heroku.com/articles/heroku-cli

$ heroku login
heroku: Press any key to open up the browser to login or q to exit:
Opening browser to https://cli-auth.heroku.com/auth/browser/c037d3e6-1359-446c-b26a-8589d07de256
heroku: Waiting for login... |

Heroku 客户会打开默认的浏览器，提示登录确认，确认后如下

$ heroku login
heroku: Press any key to open up the browser to login or q to exit:
Opening browser to https://cli-auth.heroku.com/auth/browser/c037d3e6-1359-446c-b26a-8589d07de256
Logging in... done
Logged in as xxx@gmail.com

初始化仓库提交到本地

$ git init
Initialized empty Git repository in E:/2019/0000/spring-boot-heroku/.git/

$ git add
........

$ git commit -am "hello heroku"

创建应用

$ heroku create spring-boot-heroku
Creating ⬢ spring-boot-heroku... !
 !    Name spring-boot-heroku is already taken

## 如上提示名称已存在，换个名称再试
$ heroku create spring-boot-heroku-gradle
Creating ⬢ spring-boot-heroku-gradle... done
https://spring-boot-heroku-gradle.herokuapp.com/ | https://git.heroku.com/spring-boot-heroku-gradle.git

推送到远程仓库

创建应用时，heroku 已经为我们添加了远程地址 https://git.heroku.com/spring-boot-heroku-gradle.git ，下面开始推送代码构建项目

$ git push heroku master

出现上面的信息，我们的应用就部署成功了，下面可以打开浏览器试试了，访问地址：https://spring-boot-heroku-gradle.herokuapp.com
