在开始项目之前,确保您已经安装了以下工具和技术:
- MySQL 数据库:用于存储和管理数据。
- Java 后端:用于创建后端应用程序,提供数据 API 和数据库连接。
- Vue.js 前端:用于构建前端界面,呈现数据可视化图表。
- ECharts:用于创建各种类型的图表和数据可视化。
步骤 1: 创建表 以及生成数据
-- 创建产品表
CREATE TABLE a_products (
product_id INT PRIMARY KEY COMMENT '产品ID',
product_name VARCHAR(255) COMMENT '产品名称',
unit_price DECIMAL(10, 2) COMMENT '产品单价(带两位小数)'
) COMMENT '存储产品信息';
-- 创建销售表
CREATE TABLE a_sales (
sale_id INT PRIMARY KEY COMMENT '销售ID',
product_id INT COMMENT '产品ID(外键,关联到products表)',
sale_date DATE COMMENT '销售日期',
quantity INT COMMENT '销售数量',
revenue DECIMAL(10, 2) COMMENT '销售收入(带两位小数)'
) COMMENT '存储销售数据';
-- 插入产品数据
INSERT INTO a_products (product_id, product_name, unit_price) VALUES
(1, 'Product A', 10.50),
(2, 'Product B', 15.75);
-- 插入销售数据
INSERT INTO a_sales (sale_id, product_id, sale_date, quantity, revenue)
VALUES
(1, 1, '2023-11-01', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(2, 1, '2023-11-02', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(3, 1, '2023-11-03', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(4, 1, '2023-11-04', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(5, 1, '2023-11-05', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(6, 1, '2023-11-01', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(7, 1, '2023-11-02', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(8, 1, '2023-11-03', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(9, 1, '2023-11-04', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(10, 1, '2023-11-05', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2));
-- For product_id 2
INSERT INTO a_sales (sale_id, product_id, sale_date, quantity, revenue)
VALUES
(11, 2, '2023-11-01', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(12, 2, '2023-11-02', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(13, 2, '2023-11-03', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(14, 2, '2023-11-04', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(15, 2, '2023-11-05', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(16, 2, '2023-11-01', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(17, 2, '2023-11-02', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(18, 2, '2023-11-03', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(19, 2, '2023-11-04', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2)),
(20, 2, '2023-11-05', FLOOR(RAND() * 20) + 1, ROUND(RAND() * 100, 2));
步骤2.数据库查询 SQL
-- 查询销售数据
SELECT
s.sale_date AS saleDate,
p.product_name AS productName,
COALESCE(SUM(s.quantity), 0) AS totalQuantity,
COALESCE(SUM(s.revenue), 0) AS totalRevenue
FROM a_products p
LEFT JOIN a_sales s ON p.product_id = s.product_id
GROUP BY s.sale_date, p.product_name
查询结果:
步骤3. 创建实体类
import lombok.Data;
import java.util.List;
@Data
public class SalesDTO {
@ApiModelProperty(value = "日期")
private String saleDate;
@ApiModelProperty(value = "产品名")
private String productName;
@ApiModelProperty(value = "销售数量")
private int totalQuantity;
@ApiModelProperty(value = "销售额")
private double totalRevenue;
// 省略构造函数、getter和setter 如果引入了lombok.Data不需要
}
步骤四: SalesMapper
public interface SalesMapper {
/**
* 根据产品名称统计产品售出数量
* @param
* @return
*/
List<SalesDTO> getProductSalesSummary(@Param("productName") String productName);
/**
* 获取所有产品
* @return
*/
List<String> getAllProductName();
}
步骤五:SalesMapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="org.jeecg.modules.statistics.mapper.SalesMapper">
<resultMap id="SalesDTOResultMap" type="org.jeecg.modules.statistics.entity.SalesDTO">
<id property="saleDate" column="saleDate"/>
<result property="productName" column="productName"/>
<result property="totalQuantity" column="totalQuantity"/>
<result property="totalRevenue" column="totalRevenue"/>
</resultMap>
<select id="getProductSalesSummary" resultMap="SalesDTOResultMap">
SELECT
s.sale_date AS saleDate,
p.product_name AS productName,
COALESCE(SUM(s.quantity), 0) AS totalQuantity,
COALESCE(SUM(s.revenue), 0) AS totalRevenue
FROM a_products p
LEFT JOIN a_sales s ON p.product_id = s.product_id
<where>
<if test="productName != null and productName != ''">
and p.product_name =#{productName}
</if>
</where>
GROUP BY s.sale_date, p.product_name
</select>
<select id="getAllProductName" resultType="java.lang.String">
SELECT product_name FROM a_products GROUP BY product_name
</select>
</mapper>
步骤七:SalesController
package org.jeecg.modules.statistics.controller;
import groovyjarjarpicocli.CommandLine;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.apache.xmlbeans.impl.inst2xsd.SalamiSliceStrategy;
import org.jeecg.common.api.vo.Result;
import org.jeecg.modules.statistics.entity.SalesDTO;
import org.jeecg.modules.statistics.mapper.SalesMapper;
import org.jeecg.modules.statistics.service.IKgOrderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.*;
import java.util.stream.Collectors;
@RestController
@RequestMapping("/sales")
@Api(tags = "统计图表示例")
@Slf4j
public class SalesController {
@Autowired
private SalesMapper salesMapper;
@ApiOperation(value = "统计图表示例-A", notes = "统计图表示例-A")
@GetMapping(value = "/summary")
public Result<Map<String, Object>> getSalesSummary() {
//也可以包装一个实体类返回
Result<Map<String, Object>> result = new Result<>();
Map<String, Object> resultMap = new HashMap<>();
// 获取所有产品名称列表
List<String> distinctProductNames = salesMapper.getAllProductName();
// 设置起始日期为 "2023-11-01" 也可以获取系统时间
LocalDate startDate = LocalDate.parse("2023-11-01");
// 生成近五天的日期列表
List<String> distinctSaleDates = new ArrayList<>();
for (int i = 0; i < 5; i++) {
LocalDate date = startDate.plusDays(i);
distinctSaleDates.add(date.format(DateTimeFormatter.ISO_DATE));
}
List<Map<String, Object>> seriesData = new ArrayList<>();
// 遍历每个产品名称
for (String distinctProductName : distinctProductNames) {
// 根据产品名称获取产品销售数据
List<SalesDTO> productSalesSummary = salesMapper.getProductSalesSummary(distinctProductName);
Map<String, Object> seriesItem = new HashMap<>();
seriesItem.put("name", distinctProductName);
List<Integer> quantityList = new ArrayList<>();
// 遍历日期列表
for (String distinctSaleDate : distinctSaleDates) {
// 使用 Optional 包装以处理空值情况
Optional<SalesDTO> matchingSale = productSalesSummary.stream()
.filter(dto -> dto.getSaleDate().equals(distinctSaleDate))
.findFirst();
if (matchingSale.isPresent()) {
// 如果存在匹配的销售数据,添加到数量列表中
quantityList.add(matchingSale.get().getTotalQuantity());
} else {
// 如果没有匹配的销售数据 设置为0
quantityList.add(0);
}
}
seriesItem.put("data", quantityList);
seriesData.add(seriesItem);
}
resultMap.put("dates", distinctSaleDates);
resultMap.put("series", seriesData);
result.setResult(resultMap);
return result;
}
}
响应结果
步骤8:通过cdn引入echarts --解决打包过大问题
找到index.html
在index.html 加入以下代码
<script src="https://cdn.jsdelivr.net/npm/echarts@5.3.0/dist/echarts.min.js"></script>
步骤9:vue.js 加载数据与Echarts 图表
<template>
<!-- 柱状图容器 -->
<div class="bar-chart-container">
<div ref="barChart" class="echarts-chart"></div>
</div>
</template>
<script>
// 导入 API 请求方法
import {
getAction
} from '@/api/manage';
export default {
data() {
return {
// API 请求的 URL 集合

textStyle: {
fontSize: 12, // 图例项的字体大小
},
right: '30%', // 图例相对于容器右侧的距离
},
// 工具箱配置 就是右上角可以下载原图 展示数据视图那个工具
toolbox: {
show: true, // 是否显示工具箱
feature: {
dataZoom: {}, // 数据区域缩放工具
dataView: {
readOnly: false // 是否只读
},
magicType: {
type: ['line', 'bar'] // 切换图表类型工具
},
restore: {}, // 还原工具
saveAsImage: {} // 保存为图片工具
},
right: '10%', // 工具箱相对于容器右侧的距离
},
},
};
},
mounted() {
// 页面加载后调用获取销售数据的方法
this.getSalesSummaryLoad();
},
methods: {
// 获取销售数据的方法
getSalesSummaryLoad() {
// 调用 API 请求获取销售数据
getAction(this.url.getSalesSummary, {}).then((res) => {
if (res.success) {
console.log(res)
const data = res.result;
// 更新图表的 X 轴和 Series 数据
this.chartOptions.xAxis.data = data.dates;
this.chartOptions.series = data.series.map(item => {
return {
...item,
type: "line"
};
});
// 初始化图表
this.initChart();
}
});
},
// 初始化 ECharts 图表的方法
initChart() {
// 创建 ECharts 实例
this.chart = echarts.init(this.$refs.barChart);
// 设置图表宽度和高度
const chartWidth = 1200;
const chartHeight = 500;
// 调整图表大小
this.chart.resize({
width: chartWidth,
height: chartHeight
});
// 设置图表配置
this.chart.setOption(this.chartOptions);
},
},
};
</script>
<style scoped>
.bar-chart-container {}
</style>
