新建icon component:

<template>

</template>

<script>
export default {
  name: "MedalIcon"
}
</script>

d在路由配置中引用component:

import MedalIcon from '@/components/icon/MedalIcon.vue';



// 路由配置
const options = {
    routes: [
                       {
                            path: 'medal-config',
                            name: '勋章配置',
                            meta: {
                                icon: {
                                    component:  MedalIcon,
                                },
                            },
                            component: () => import('@/pages/system/medal-config'),
                        },
    ]
}

修改menu.js中的renderIcon方法中, 增加代码：

renderIcon: function (h, icon, key) {
            if (this.$scopedSlots.icon && icon && icon !== 'none') {
                const vnodes = this.$scopedSlots.icon({icon, key})
                vnodes.forEach(vnode => {
                    vnode.data.class = vnode.data.class ? vnode.data.class : []
                    vnode.data.class.push('anticon')
                })
                return vnodes
            }

            //自定义图标 start
            if (typeof icon === 'object' && icon.component) {
                return !icon || icon == 'none' ? null : h(Icon, {props: {component: icon.component}})
            }
            //自定义图标 end


            return !icon || icon == 'none' ? null : h(Icon, {props: {type: icon}})
        },

最终效果：
