【水果管理系统】Spring Boot+MyBatis Plus+Vue+Element UI+ECharts+axios

1.搭建数据库

create schema apple;
use apple;

CREATE TABLE `fruit` (
  `id` int NOT NULL AUTO_INCREMENT,
  `name` varchar(11) DEFAULT NULL,
  `sale` int DEFAULT NULL,
  `icon` varchar(300) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8;

INSERT INTO `fruit` VALUES (1,'苹果',333,'https://i02piccdn.sogoucdn.com/7a0b5e51b03f3245'),(2,'香蕉',133,'https://i03piccdn.sogoucdn.com/3506f1c96181e955'),(3,'橘子',299,'https://i03piccdn.sogoucdn.com/6c8d3681470e2f24'),(6,'火龙果',133,'https://i02piccdn.sogoucdn.com/49fb5d2c90f97382'),(15,'芒果',222,'https://i02piccdn.sogoucdn.com/283567c3cb9018ab');

2.搭建Vue项目

cdm ： vue ui

2.1 创建普通项目

ECharts图标库

2.2 安装插件

2.3 router.index.js

2.4 Bar.vue

<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({
