main.js中 

// 插件-路由
import VueRouter from 'vue-router'
Vue.use(VueRouter)
import {routes} from "./routes";

//自动注册路由- page目录下的一级vue文件
require.context('./page', true, /\.vue$/).keys().forEach(fileName => {
  let componentName = fileName.replace(/^\.\//,'').replace(/\.vue$/,'');
  let  temp = {
    path: '/'+componentName,
    component:resolve => require(["@/page/"+componentName], resolve)
  }
  routes.push(temp)
});

const router = new VueRouter({
  routes
})

page文件夹和main.js同级
