2024年1月Java项目开发指南10：vite+Vue3项目创建

新建项目

安装router

npm install vue-router

在src下新建目录router，在目录下新建index.js

在index.js里面配置路由

import { createRouter, createWebHistory } from 'vue-router';

// 定义路由
const routes = [
  //在这里配置路由
];

// 创建路由实例
const router = createRouter({
    history: createWebHistory(),
    routes,
});

export default router;

然后编辑main文件

import { createApp } from 'vue'
import './style.css'
import router from "./router/index.js";
import App from './App.vue'
let app = createApp(App)
app.use(router).mount('#app')

安装AntDesignVue

官方文档：
https://www.antdv.com/docs/vue/getting-started-cn

npm i --save ant-design-vue

安装后再main.js中配置

import { createApp } from 'vue'
import './style.css'
import router from "./router/index.js";
import Antd from 'ant-design-vue';
import App from './App.vue'
import 'ant-design-vue/dist/reset.css';
let app = createApp(App)
app.use(router).use(Antd).mount('#app')

安装AntDesignVue的icon图标

npm install --save @ant-design/icons-vue

修改App.vue

<script setup>

</script>

<template style="width: 100%;height: 100%;margin: 0;padding: 0">
  <router-view style="width: 100%;height: 100%"></router-view>
</template>

<style scoped>

</style>

创建视图view

在src下创建views文件夹
在文件夹下创建ControlView.vue作为控制中心页面
同时配置路由

{  
	path: '/',
	name: 'ControlCenter',
	component: () => import('../views/ControlView.vue')
}

router.index.js文件配置如下

import { createRouter, createWebHistory } from 'vue-router';

// 定义路由
const routes = [
    {
        path: '/',
        name: 'ControlCenter',
        component: () => import('../views/ControlView.vue'),

    },
    // 其他路由...
];

// 创建路由实例
const router = createRouter({
    history: createWebHistory(),
    routes,
});

export default router;

修改index.html

删除style.css里面#app的样式

你可以尝试在 ControlView.vue这个文件写代码，然后运行看看效果

我这个文件的代码贴出来你们参考一下

<template style="width: 100%">
  <div class="flex-layout" style="display: flex; flex-direction: column; min-height: 100vh;">
  <a-layout class="layout" style="width: 100%;flex:1">

<script setup>
import {onMounted, ref, watchEffect} from 'vue';
import {useRoute} from "vue-router";


const selectedKeys = ref(['1']);
const route = useRoute();
// 使用 watchEffect 来监听路由变化
watchEffect(() => {
  // 根据路由路径更新 selectedKeys
  switch (route.path) {
    case '/index':
      selectedKeys.value = ['1'];
      break;
    case '/about':
      selectedKeys.value = ['2'];
      break;
    case '/admin':
      selectedKeys.value = ['3'];
      break;
    default:
      selectedKeys.value = ['1']; // 默认选中的 key
      break;
  }
});


const isLoggedIn = ref(false);
const user = ref({
  avatar: '',
  nickname: localStorage.getItem("username")
});

onMounted(async () => {

});

function handleLogout() {
  // 退出登录逻辑
  localStorage.removeItem('token');
  isLoggedIn.value = false;
  user.value = {avatar: '', nickname: ''};
}
</script>
<style scoped>
.site-layout-content {

.flex-layout {
  display: flex;

  min-height: 100vh; /* 确保容器至少占据整个视口高度 */
}

.layout {
  flex: 1; /* 让布局占据所有可用空间 */
  display: flex;
  flex-direction: column;
}

.footer {
  /* 页脚样式，根据需要自定义 */
  margin-top: auto; /* 将页脚推到容器的底部 */
}
</style>

我不建议你抄我代码。
请自行查阅AntDesignVue官方文件，自己设计界面
