How to set key filed for certain component in router-view?

[FishHawk]

My website use router-view and keep-alive together like this:

  <router-view v-slot="{ Component }">
    <keep-alive
      :exclude="[
        'WebNovel',
        'WebNovelEdit',
      ]"
    >
      <component :is="Component" />
    </keep-alive>
  </router-view>

WebNovel and WebNovelEdit need change page content based on novelId.

Now I want to recreate the component only when the novelId changes. I know I can calculate the key based on the component name, but is there a more elegant way to do it?
