      drawer: false,

使用：
第一种方式：直接修改APP.vue
但这种办法不是很友好，需要兼容各个vue页面的大小，如果页面展示太长，则显示在中间。对于前端小白来说，去实现这个功能花很多时间也没必要。所以采用了第二种方式

<template>
  <div id="app">
    <router-view />
    <app-footer></app-footer>
  </div>
</template>

<script>
import Footer from './components/footer/footer.vue'

export default {
  name: 'App',
  components: {
    'app-footer': Footer,
  },
}
</script>

第二种方式：直接在vue组件里调用改footer组件
比如我在某个组件vue页面下的分页组件下面插入：

    <pagination
      v-show="total > 0"
      :total="total"
      :page.sync="listQuery.page"
      :limit.sync="listQuery.limit"
      @pagination="getList"
    />
    <Footer></Footer>  //页脚

script下需要改动如下两行。

<script>
import Footer from '@/components/footer/footer'  // 导入页脚
export default {
  `components: { Pagination, Footer },

这样生成的效果始终在页面的底部，
