springboot maven打包jar运行,springboot mybatis druid,demo源码
2024-04-22 03:04:12
注：本文介绍的mysql版本是5.x ，如果mysql升级到8 有几个地方需要改动
https://blog.csdn.net/a704397849/article/details/108396563
之前分享一篇 springboot mybatis 多数据源 Druid连接池，demo源码 https://blog.csdn.net/a704397849/article/details/94416778
但那只是在idea运行，没有maven打包jar运行。现在介绍在上篇的基础上增加 打包jar 运行,最后附源码

打包jar后运行
在idea中 打开项目的命令行终端
输入清除打包命令 mvn clean package
打包完毕
如果没有设置输出目录的话，打包生成的jar包默认会生成在项目根目录下的target目录，cd target 进入生成的jar包目录
运行：java -jar mybatis_package_demo-0.0.1-SNAPSHOT.jar

注：这里是在本地运行jar包，也可以上传到服务上运行，当然java命令直接运行也太简陋了，我之前有分享过一个jar运行脚本有兴趣的可以看看

初次打包springboot jar运行会遇到多少坑我就不想提了，希望能帮助到还不能成功打包springboot项目jar包运行的同学。当然这里只是介绍了一个可以正常打包jar的demo,更多的打包过程需要深入。
