问题描述

自己写了个demo,想放到阿里云的服务器上跑,阿里云上的环境是用的镜像市场里的centos6.9+jdk8+nginx1.12.2,但是还预装了一个tomcat,他原先有的demo应该是vue放到nginx中,后端用的tomcat,而我的demo用的是springboot,以jar包形式打包,放到服务器上运行前端能访问,后端也能访问,但是两个交互一直是不行,所以不知道是nginx没配置好还是别的原因

问题出现的环境背景及自己尝试过哪些方法

1.不修改springboot的端口(8081),失败
2.停止tomcat服务,修改springboot端口(8080),失败

你期待的结果是什么？实际看到的错误信息又是什么？

正常的结果应该是能交互,本地还没尝试nginx代理vue来访问后端,普通的功能比如登录,浏览器报错是
