注释掉App.tsx中的几个路由组件：

将Home.tsx中的代码使用ant Design网站中的布局进行替换

复制的代码如下：

import {
  DesktopOutlined,
  FileOutlined,
  PieChartOutlined,
  TeamOutlined,
  UserOutlined,
} from '@ant-design/icons';
import type { MenuProps } from 'antd';
import { Breadcrumb, Layout, Menu } from 'antd';
import React, { useState } from 'react';

const { Header, Content, Footer, Sider } = Layout;

type MenuItem = Required<MenuProps>['items'][number];

function getItem(
  label: React.ReactNode,
  key: React.Key,
  icon?: React.ReactNode,
  children?: MenuItem[],
): MenuItem {
  return {
    key,
    icon,
    children,
    label,
  } as MenuItem;
}

const items: MenuItem[] = [
  getItem('Option 1', '1', <PieChartOutlined />),
  getItem('Option 2', '2', <DesktopOutlined />),
  getItem('User', 'sub1', <UserOutlined />, [
    getItem('Tom', '3'),
    getItem('Bill', '4'),
    getItem('Alex', '5'),
  ]),
  getItem('Team', 'sub2', <TeamOutlined />, [getItem('Team 1', '6'), getItem('Team 2', '8')]),
  getItem('Files', '9', <FileOutlined />),
];

const App: React.FC = () => {
  const [collapsed, setCollapsed] = useState(false);

  return (
    <Layout style={{ minHeight: '100vh' }}>
      <Sider collapsible collapsed={collapsed} onCollapse={value => setCollapsed(value)}>
        <div className="logo" />
        <Menu theme="dark" defaultSelectedKeys={['1']} mode="inline" items={items} />
      </Sider>
      <Layout className="site-layout">
        <Header className="site-layout-background" style={{ padding: 0 }} />
        <Content style={{ margin: '0 16px' }}>
          <Breadcrumb style={{ margin: '16px 0' }}>
            <Breadcrumb.Item>User</Breadcrumb.Item>
            <Breadcrumb.Item>Bill</Breadcrumb.Item>
          </Breadcrumb>
          <div className="site-layout-background" style={{ padding: 24, minHeight: 360 }}>
            Bill is a cat.
          </div>
        </Content>
        <Footer style={{ textAlign: 'center' }}>Ant Design 2018 Created by Ant UED</Footer>
      </Layout>
    </Layout>
  );
};

export default App;

这里需要对代码进行修改，const App的APP需要改成View；export default App的App也需要改成View

还需要导入样式,这里我们将样式导入全局样式中去：

这样一个后台管理系统的侧边栏就做好了：

但是路由的一些跳转呀什么之类的功能还是需要自己去写的。

调整样式之后：

import {
    DesktopOutlined,
    FileOutlined,
    PieChartOutlined,
    TeamOutlined,
    UserOutlined,
} from '@ant-design/icons';
import type { MenuProps } from 'antd';
import { Breadcrumb, Layout, Menu } from 'antd';
import React, { useState } from 'react';

const { Header, Content, Footer, Sider } = Layout;

type MenuItem = Required<MenuProps>['items'][number];

function getItem(
    label: React.ReactNode,
    key: React.Key,
    icon?: React.ReactNode,
    children?: MenuItem[],
): MenuItem {
    return {
        key,
        icon,
        children,
        label,
    } as MenuItem;
}

const items: MenuItem[] = [
    getItem('Option 1', '1', <PieChartOutlined />),
    getItem('Option 2', '2', <DesktopOutlined />),
    getItem('User', 'sub1', <UserOutlined />, [
        getItem('Tom', '3'),
        getItem('Bill', '4'),
        getItem('Alex', '5'),
    ]),
    getItem('Team', 'sub2', <TeamOutlined />, [getItem('Team 1', '6'), getItem('Team 2', '8')]),
    getItem('Files', '9', <FileOutlined />),
];

const View: React.FC = () => {
    const [collapsed, setCollapsed] = useState(false);

    return (
        <Layout style={{ minHeight: '100vh' }}>
            {/* 左边侧边栏 */}
            <Sider collapsible collapsed={collapsed} onCollapse={value => setCollapsed(value)}>
                <div className="logo" />
                <Menu theme="dark" defaultSelectedKeys={['1']} mode="inline" items={items} />
            </Sider>
            {/* 右边的内容 */}
            <Layout className="site-layout">
                {/* 头部 */}
                <Header className="site-layout-background" style={{ paddingLeft: '16px' }} >
                    <Breadcrumb style={{ lineHeight: '64px' }}>
                        <Breadcrumb.Item>User</Breadcrumb.Item>
                        <Breadcrumb.Item>Bill</Breadcrumb.Item>
                    </Breadcrumb>
                </Header>
                {/* 右边内容-白色底的盒子 */}
                <Content style={{ margin: '16px 16px 0' }} className="site-layout-background">
                    {/* 窗口部分 */}

                </Content>
                {/* 右边底部 */}
                <Footer style={{ textAlign: 'center', padding: 0, lineHeight: '48px' }}>Ant Design 2018 Created by Ant UED</Footer>
            </Layout>
        </Layout>
    );
};

export default View;

首页展示效果如下：
