设置菜单路由时，代码如下：
{
path: '/materieluse',
component: Layout,
meta: {
title: '仓库管理',
icon: 'component'
},
children: [{
path: 'materielList',
com...
设置菜单路由时，代码如下：
{
path: '/materieluse',
component: Layout,
meta: {
title: '仓库管理',
icon: 'component'
},
children: [{
path: 'materielList',
component: () => import('@/views/materieluse/materielList'),
name: 'icons',
meta: { title: '请料管理' }
}, {
path: 'itemDbList',
component: () => import('@/views/materieluse/itemDbList'),
name: 'icons',
meta: { title: '项目仓库' }
}]
},面板中的对应标签失效，经查资料，得知：name: "router-name"; //设定路由的名字，一定要填写不然使用<keep-alive>时会出现各种问题,同时noCache: true 设置了也会失效
因此正确代码如下：
{
path: '/materieluse',
component: Layout,
meta: {
title: '仓库管理',
icon: 'component'
},
children: [{
path: 'materielList',
component: () => import('@/views/materieluse/materielList'),
name: 'materielList',
meta: { title: '请料管理' }
}, {
path: 'itemDbList',
component: () => import('@/views/materieluse/itemDbList'),
name: 'itemDbList',
meta: { title: '项目仓库' }
}]
