关于一个组件多路由使用需要缓存

请教下大佬这个用法创建后使用push打开不回去创建组件是啥原因
vite4 vue3.2

          <router-view>
            <template #default="{ Component, route }">
              <keep-alive>
                <component :is="formatComponentInstance(Component,route)"/>
              </keep-alive>
            </template>
          </router-view>

​const formatComponentInstance = (Component: any, route: any) => {
let wrapper;
if (Component) {
const wrapperName = route.name;
if (wrapperMap.has(wrapperName)) {
console.log("从缓存中读取")
wrapper = wrapperMap.get(wrapperName);
} else {
wrapper = {
name: wrapperName,
render() {
return h(Component);
},
};
wrapperMap.set(wrapperName, wrapper);
console.log("创建全新组件")
}
return h(wrapper);
}
}

​不知道为啥返回不了,可以创建就是不能打开原来的
