springboot的打包方式有很多種。有打成war的，有打成jar的，也有直接提交到github，通過jekins進行打包部署的。這裡主要介紹如何打成jar進行部署。不推薦用war，因為springboot適合前後端分離，打成jar進行部署更合適。首先需要在application.yml當中配置埠

server:
    port: 8080

maven配置檔案

注意最下面的build這塊一定要配置否則打jar的時候會說找不 到主類

在啟動類當中加上extends SpringBootServletInitializer並重寫configure方法，這是為了打包springboot專案用的。

然後按照順序執行clean再build,我是用sts

然後就會出來我們需要的jar

然後到這個jar的根目錄下執行java -jar smallsystem-0.0.1-SNAPSHOT.jar 這個執行方式windows和linux上都一樣

如果是阿里雲上的，需要通過阿里雲把你指定的埠開放，如果是虛擬機器上的，需要把防火牆什麼的關掉，開放埠即可。
