webpack+vue开发打包的项目放到服务器上访问不了

我在本地使用vue-cli搭建的项目,tomcat端口号是8080,我自己作了一下把webpack配置的端口号改为8088,目的是为了锻炼自己跨域调接口的能力。本地都ok,都能跑,但是使用npm run build打包后放到服务器上的tomcat下的webapps文件夹下没有作用。
我访问ip:8080显示的是tomcat页面而不是我项目的页面,后面加上项目名就报404,仔细看看本地也是localhost:8088/#/,后面并没有项目名能访问啊,为什么在服务器上不能访问呢？
后来怀疑是不是服务器有问题,因为是我昨天才踩了无数坑搭好的,把老项目放上去完全能跑,说明服务器没问题啊,那么只能是我自己项目的问题了,可是个人真的蛮菜的,始终不知道为什么,只能来社区求助了,谢谢前辈们了！
