项目部署踩坑记录

在部署SpringBoot后端和Vue前端时，双双踩坑，在此记录

1.Springboot部署

在部署后端时，在本地的idea中能正常运行，而且使用jar包也能正常运行，但如果把jar包导入到服务器

在使用java -jar xxx.jar时就会报错。

很疑惑，明明都是下载了JDK1.8。代码也一样为什么还会报错。

经过一番痛苦的查阅后，在一篇文章中找到类似的错误，说要留意报错信息里的最后一个Caused by

Caused by: java.lang.ClassNotFoundException: javafx.util.Pair

然后尝试了把代码中和Pair相关的方法都注释掉，果然就正常运行了。

既然这样，那就一定是JDK的问题。

本地项目中使用的是

Amazon Corretto 8 的下载内容 - Amazon Corretto

而服务器使用的是

Java Downloads | Oracle 中国

虽然都是JDK1.8，但不知道为什么就算存在差异。

2.Vue+vite nginx部署
