一、监听路由
watch: {
 // 方法1 //监听路由是否变化
  '$route' (to, from) {
   if(to.query.id !== from.query.id){
            this.id = to.query.id;
            this.init();//重新加载数据
        }
  }
}
//方法 2  设置路径变化时的处理函数
watch: {
'$route': {
    handler: 'init',
    immediate: true
  }
}

二、添加key
<router-view :key="$route.fullpath"></router-view>
