ElementUI——案例1用户管理（基于SpringBoot）_carousel 走马灯 springboot

1.前期准备

备注：主要涉及组件container组件，导航菜单组件，router路由组件，carousel 走马灯组件，Image组件，Table表格组件

#1.在项目开发目录使用脚手架新建vue项目（需要提前安装好node和webpack）
vue init webpack element_user(项目名)
#2.进入当前构建好的vue项目下，下载elementui依赖
cd element_user
npm i element-ui -S
#3.进入项目src目录下的main.js文件加入配置
# 相当于将elementui所有样式和组件引入
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
#将elementui全局组件注册到实例上
Vue.use(ElementUI);

搭建布局如下

2.案例开发

1.删除项目中components目录下的HelloWorl文件搭建如下结构，components下分模块创建目录

2.Index.vue

<template lang="">
    <div>
        <h1>主页</h1>
    </div>
</template>
<script>
export default {
}
</script>
<style lang="">

        <h1>用来显示用户列表</h1>
    </div>
</template>
<script>
export default {

App.vue中使用导航菜单组件，实现导航栏功能；底部添加路由，绑定路由功能

<template>
  <div id="app">
    <el-container>
      <el-header>
          <!--导航菜单-->
          <el-menu :default-active="activeIndex" class="el-menu-demo" mode="horizontal" @select="handleSelect">
              <el-menu-item index="/index">主页</el-menu-item></el-menu-item>
              <el-menu-item index="/userslist">用户管理</el-menu-item></el-menu-item></el-menu-item>
              <el-menu-item index="/mags">消息中心</el-menu-item>
              <el-menu-item index="/orders">订单管理</el-menu-item>
            </el-menu>
      </el-header>
      <el-main>
          <!-- 路由组件 -->
          <router-view/>
      </el-main>
    </el-container>
  </div>
</template>
<script>
export default {
  name: 'App',
  data() {
      return {
        activeIndex: this.$route.path,//获取当前路由路径，解决刷新网页报错问题
      };
    },
    methods: {
      handleSelect(key, keyPath) {
        console.log(key, keyPath);
        // 切换路由
        this.$router.push(key);
      }
    }
}
</script>
<style>
</style>

3.路由设置router下的index.js

import Vue from 'vue'
import Router from 'vue-router'
import Index from '../components/Index'
import List from '../components/user/List'
Vue.use(Router)

export default new Router({
  routes: [
  {
    path:'/',//配置根路由
    component:Index
  },
    {
      path: '/index',
      component: Index
    },
    {
      path:'/userslist',
      component:List
    }
  ]
})

3.1 走马灯（轮播图）

修改Index.vue

<template lang="">
    <div>
        <el-carousel indicator-position="outside">
            <el-carousel-item v-for="item in imgs" :key="item">
                <el-image
                :src="item"
                fit="contain"></el-image>
            </el-carousel-item>
          </el-carousel>
    </div>
</template>
<script>
    import homeImg1 from "../assets/imgs/zjl1.jpg";
    import homeImg2 from "../assets/imgs/zjl2.jpg";
    import homeImg3 from "../assets/imgs/zjl3.jpg";
    import homeImg4 from "../assets/imgs/zjl4.jpg";
    import homeImg5 from "../assets/imgs/zjl5.jpg";
export default {
   name:"Index",
   data(){
    return {
        imgs:[homeImg1,homeImg2,homeImg3,homeImg4,homeImg5]
    }
   }
}

<template lang="">

        <el-table
    :data="tableData.filter(data => !search || data.name.toLowerCase().includes(search.toLowerCase()))"
    border
    style="width: 100%">

4.集合SpringBoot后台实现数据异步请求

准备工作：静态页面已经搭建好，现在将数据改为动态数据，后台使用SpringBoot

1.Vue前台

• 安装axios

npm i axios -S
1

• main.js中引入axios

import axios from 'axios'
Vue.prototype.$http=axios#通过修改原型链方式引入
1
2

• 修改List.vue脚本内容

<script>
export default {
    methods: {
      handleEdit(index, row) {
        console.log(index, row);
      },
      handleDelete(index, row) {
        console.log(index, row);
      }
    },
    data() {
      return {
        tableData: [],
        search: ''
      }
    },
    created() {
        this.$http.get("http://localhost:8989/user/findAll").then(res=>{
            //回调中获取响应结果
            this.tableData = res.data;//将tableData值设为响应结果
        })
    },
}
</script>

2.SpringBoot后台

本文后台主要涉及核心代码

@RestController
@CrossOrigin(origins = "*")//全局跨域，解决跨域相关问题
@RequestMapping("user")
public class UserController {
    @Autowired
    private UserService userService;
    @GetMapping("findAll")
    public List<User> findAll(){
        return userService.findAll();
    }
}
