部署springboot项目，jar包和war的方式目前我用过，两者各有优缺点。

比如jar包部署，命令比较简单，但是如果想修改一个配置或者换个jar，需要重新打包部署。

war包部署的话，需要依赖外置tomcat，工作量也很大。

这里推荐使用一个maven插件，appassembler-maven-plugin，打包后会将配置文件、jar包分离，并且还提供windows/linux一键部署的脚本。

一、配置方法

在pom.xml里设置build如下代码，为了方便新人学习，这里创建了一个springboot-demo项目，pom.xml完整代码如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

二、效果图

执行mvn clean install 打包

在target下找到springboot-demo，里面有conf，lib和bin三个目录，分别对应resources配置文件、jar包和启动脚本(windows系统直接双击start.bat, linux需要执行 nohup sh start.sh &)
