Spring Boot 笔记 025 主界面

1.1 路由搭建

1.1.1 安装vue router

npm install vue-router@4

1.1.2 在src/router/index.js中创建路由器，并导出

import { createRouter, createWebHistory } from 'vue-router'//导入组件
import LoginVue from '@/views/Login.vue'
import LayoutVue from '@/views/LayoutGeji.vue'//定义路由关系
const routes = [{ path: '/login', component: LoginVue },{ path: '/', component: LayoutVue },
]//创建路由器
const router = createRouter({history: createWebHistory(),routes: routes
})//导出路由
export default router

1.1.3 在vue应用实例中使用vue-router

1.1.4 声明router-view标签，展示组件内容

1.1 自动跳转

import { useRouter } from 'vue-router'const router = useRouter()const login =async ()=>{//调用接口,完成登录let result =  await userLoginService(registerData.value);ElMessage.success(result.msg ? result.msg : '登录成功')//跳转到首页 路由完成跳转router.push('/')
}

1.2 子路由

1.2.1 配置子路由

import { createRouter, createWebHistory } from 'vue-router'//导入组件
import LoginVue from '@/views/Login.vue'
import LayoutVue from '@/views/LayoutGeji.vue'import ArticleCategoryVue from '@/views/article/ArticleCategory.vue'
import ArticleManageVue from '@/views/article/ArticleManage.vue'
import UserAvatarVue from '@/views/user/UserAvatar.vue'
import UserInfoVue from '@/views/user/UserInfo.vue'
import UserResetPasswordVue from '@/views/user/UserResetPassword.vue'//定义路由关系
const routes = [{ path: '/login', component: LoginVue },{path: '/', component: LayoutVue,redirect:'/article/manage', children: [{ path: '/article/category', component: ArticleCategoryVue },{ path: '/article/manage', component: ArticleManageVue },{ path: '/user/info', component: UserInfoVue },{ path: '/user/avatar', component: UserAvatarVue },{ path: '/user/resetPassword', component: UserResetPasswordVue }]}
]//创建路由器
const router = createRouter({history: createWebHistory(),routes: routes
})//导出路由
export default router

1.2.2 声明router-view

1.2.3 为菜单项 el-menu-item 设置index属性，设置点击后的路由路径

```html
<script setup>
import {Management,Promotion,UserFilled,User,Crop,EditPen,SwitchButton,CaretBottom
} from '@element-plus/icons-vue'
import avatar from '@/assets/default.png'
</script><template><el-container class="layout-container"><!-- 左侧菜单 --><el-aside width="200px"><div class="el-aside__logo"></div><el-menu active-text-color="#ffd04b" background-color="#232323"  text-color="#fff"router><el-menu-item index="/article/category"><el-icon><Management /></el-icon><span>文章分类</span></el-menu-item><el-menu-item index="/article/manage"><el-icon><Promotion /></el-icon><span>文章管理</span></el-menu-item><el-sub-menu ><template #title><el-icon><UserFilled /></el-icon><span>个人中心</span></template><el-menu-item index="/user/info"><el-icon><User /></el-icon><span>基本资料</span></el-menu-item><el-menu-item index="/user/avatar"><el-icon><Crop /></el-icon><span>更换头像</span></el-menu-item><el-menu-item index="/user/resetPassword"><el-icon><EditPen /></el-icon><span>重置密码</span></el-menu-item></el-sub-menu></el-menu></el-aside><!-- 右侧主区域 --><el-container><!-- 头部区域 --><el-header><div>小学生程序员：<strong>小白</strong></div><el-dropdown placement="bottom-end"><span class="el-dropdown__box"><el-avatar :src="avatar" /><el-icon><CaretBottom /></el-icon></span><template #dropdown><el-dropdown-menu><el-dropdown-item command="profile" :icon="User">基本资料</el-dropdown-item><el-dropdown-item command="avatar" :icon="Crop">更换头像</el-dropdown-item><el-dropdown-item command="password" :icon="EditPen">重置密码</el-dropdown-item><el-dropdown-item command="logout" :icon="SwitchButton">退出登录</el-dropdown-item></el-dropdown-menu></template></el-dropdown></el-header><!-- 中间区域 --><el-main><router-view></router-view></el-main><!-- 底部区域 --><el-footer>大事件 ©2023 Created by 黑马程序员</el-footer></el-container></el-container>
