因为jeecg路由是动态路由渲染，默认跳转会跳转到当前主路由的<router-view />里面，所以要想实现跳转的需求，就要修改框架默认的一些内容。

1、router.config.js

export const constantRouterMap = [// bigDataScreen为大屏页面的关键词{path: '/bigDataScreen',component: BlankLayout,redirect: '/bigDataScreen/index1',children: [{path: 'index1',name: 'BigDataScreenIndex1',component: () => import('@/views/bigDataScreen/index1/index'),},{path: 'index2',name: 'BigDataScreenIndex2',component: () => import('@/views/bigDataScreen/index2/index'),}]},{path: '/404',component: () => import(/* webpackChunkName: "fail" */ '@/views/exception/404')}
]

2、memu/index.js

}

3、正常注册菜单
