Upload文件时报错

pdj

新手，按照视频教程Upload测试报错，麻烦哪位给看下，哪里有问题。谢谢！
1. 直接新建Upload.vue 复制黏贴教程代码时，网页报错，后台不报错
   
    前端网页报错：Failed to load resource: the server responded with a status of 404 (Not Found)
    后端报错内容：空

1教程代码上传网页报错

2. 修改教程代码中一下部分，后台报token错误
    教程给出代码 ===》 import { ACCESS_TOKEN } from "@/store/mutation-types"
    改为  ===》 import { ACCESS_TOKEN } from "../../store/mutation-types"

     前端网页报错：POST http://localhost:3000/edu/url.fileUpload 404 (Not Found)

2.2.修改教程代码上传网页报错

     后台报错内容：2019-05-05 05:43:11.279 [http-nio-8080-exec-4] ERROR o.a.c.c.C.[.[.[/jeecg-boot].[dispatcherServlet]:182 - Servlet.service() for servlet [dispatcherServlet] in context with path [/jeecg-boot] threw exception [org.apache.shiro.authc.AuthenticationException: Token失效，请重新登录] with root causeorg.apache.shiro.authc.AuthenticationException: token非法无效!
