spring boot + vue 项目初始化配置

Vue 工程

• 创建 Vue 工程
• 安装 Element UI、axios 插件
• 安装 Echarts

1、执行命令

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

                            }
                        },
                        {
                            value: 133,

                            }
                        },
                        {

                }]
            });
        }
    }
