我是靠谱客的博主怕孤独吐司，最近开发中收集的这篇文章主要介绍SpringBoot项目打包为jar包My Environment打jar包生成jar包运行jar包，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

My Environment

IDEA2018.3
JDK1.8
SpringBoot2.3.0
360浏览器
项目部署一般是两种方式：
一种是打包成 jar 包直接执行，另一种是打包成 war 包放到 Tomcat 服务器下，SpringBoot一般情况下默认为jar包方式。
pom.xml：
< packaging>jar< /packaging> （默认）
< packaging>war< /packaging>

打jar包

选择 File -> Project Structure->Artifacts->Jar->Form modules with dependencies后点ok:
根据下图内容创建 jar。如图所示，选择项目，入口类等。最后一项 META-INF，默认放到 srcmainjava 目录里，如果使用默认值，没有进行其他配置，生成的 jar 有可能不会包含 META-INF 目录，导致运行 jar 出错。最好放在 srcmainresource目录中。点击ok保存。按下图所示配置：
