### 1. Vue 工程 ###

所需前端技术栈：

*  Element UI  
    网站快速成型工具；Element，一套为开发者、设计师和产品经理准备的基于 Vue 2.0 的桌面端组件库。

    Element UI官网链接：[https://element.eleme.cn/\#/zh-CN][https_element.eleme.cn_zh-CN]
 *  axios 插件  
    Axios 是一个基于 promise 的网络请求库，可以用于浏览器和 node.js  
    Axios 使用简单,包尺寸小且提供了易于扩展的接口。  
    axios 官网链接 ：[https://www.axios-http.cn/docs/intro][https_www.axios-http.cn_docs_intro]

 *  Echarts：一个使用 JavaScript 实现的开源可视化库，可以流畅的运行在 PC 和移动设备上，兼容当前绝大部分浏览器（IE9/10/11，Chrome，Firefox，Safari等），底层依赖矢量图形库 ZRender，提供直观，交互丰富，可高度个性化定制的数据可视化图表。

1、执行命令 安装echarts

cnpm install echarts@4.9.0 --save

2、main.js 中引入

import echarts from 'echarts'
    Vue.prototype.$echarts = echarts

3、代码

<template>
        <div id="myChart" :style="{width: '800px', height: '600px'}"></div>
    </template>
    <script>
        export default {
            name: 'Echarts',
            mounted(){
                // 基于准备好的dom，初始化echarts实例
                let myChart = this.$echarts.init(document.getElementById('myChart'))
                // 绘制图表
                myChart.setOption({
                    title: {
                        text: '水果销量统计',
                        left: 'center',
                        top: 20,
                        textStyle: {
                            color: '#555555'
                        }
                    },
                    tooltip: {},
                    xAxis: {
                        data: [
                            "苹果",

                            "橘子",
                            "火龙果",
                            "葡萄",
                            "西瓜"
                        ]
                    },
                    yAxis: {},
                    series: [{
                        name: '销量',

### 2. Spring Boot 工程 ###

后端技术栈：

*  mybatis-plus  
    （简称 MP）是一个 MyBatis (opens new window)的增强工具，在 MyBatis 的基础上只做增强不做改变，为简化开发、提高效率而生。  
    ![在这里插入图片描述][fc21a5026b2042b298ebc99d97fe5fa5.png]
 *  Velocity 模板引擎  
    Velocity 是一个基于 java 的模板引擎（template engine）。它允许任何人仅仅简单的使用模板语言（template language）来引用由 java 代码定义的对象。
