1、按需加载；（1）const Shop = () => import('@/page/shop/Shop')           

 {

      path: '/shop',

      name: Shop,

      // component: resolve => require(['../page/shop/Shop'], resolve)

      component: Shop

    }可以生成多个js文件

（2）component: resolve => require(['../page/index/Index'], resolve)，这种方法所有的组件生成一个js文件
