成果展示:
一、数据源
1)可以使用自己的MySQL数据库;
2)使用我提供的数据。(免费下载)
gmall_report用于可视化的SQL文件-MySQL文档类资源-CSDN下载
二、所需工具
MySQL
IDEA
jdk1.8
Maven
三、项目框架搭建
3.1新建springboot项目
创建springboot项目有二种方式:
1)在IDEA中创建
2)在官网上创建
我喜欢在官网创建
3.1.1进入官网
官网地址(记得收藏):
https://start.spring.io/
3.1.2创建项目
注:
1)注意红色框框的地方,选择你想要的版本和与你的计算机相应的配置;
2)在1.处点击添加相关依赖;
3)在2.处点击生成初始代码并下载。
下面给出我的配置信息:
项目下载后解压,然后用IDEA打开解压后的项目。
四、后端代码编写
4.1根据需求修改pom.xml
我的pom.xml:
4.0.0 org.springframework.boot spring-boot-starter-parent2.7.1 com.example demo0.0.1-SNAPSHOT demo Demo project for Spring Boot 1.8 org.springframework.boot spring-boot-starter-weborg.mybatis.spring.boot mybatis-spring-boot-starter2.2.2 com.baomidou mybatis-plus-boot-starter3.1.2 org.springframework.boot spring-boot-devtoolsruntime true mysql mysql-connector-javaorg.projectlombok lomboktrue 1.18.4 org.springframework.boot spring-boot-starter-testtest org.springframework.boot spring-boot-starter-thymeleaf1) org.springframework.boot spring-boot-maven-pluginorg.projectlombok lombok
4.2配置数据源
1)重命名或者复制,把application.properties变为application.yml
2) 在application.yml中添加内容:
spring: datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://192.168.17.XXX:3306/gmall_report?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&zeroDateTimeBehavior=CONVERT_TO_NULL username: root password: 123456
注:要按照实际情况修改内容。
(1)192.168.17.XXX是我的MySQL所在计算机的IP地址,要修改成你的;
(2)3306:是端口号;
(3)gmall_report是用到的数据库名;
(4)root是MySQL的用户名,123456是用户相应的密码;
4.3创建目录结构
按照下图创建你的包,使其目录和下图一样。
4.4后端编写代码
想要从MySQL中提取数据,要编写entity,dao,servier,controller类或者接口,强烈建议一张一张表的编写,方便梳理。
本文用到的表有:goods,ads_area_topic,ads_order_day_count,ads_product_sale_topN,ads_user_action_count
4.4.1entity类
在entity包下面创建java类,如下图;
(1) AreaTopicEntity
import com.baomidou.mybatisplus.annotation.TableId; import com.baomidou.mybatisplus.annotation.TableName; import lombok.Data; import java.io.Serializable; @Data @TableName("ads_area_topic") public class AreaTopicEntity implements Serializable { private static final long serialVersionUID = 2L; @TableId private String dt; private String id; private String provinceName; private String regionName; private String orderDayAmount; private String paymentDayAmount; private String areaCode; }
注:
1)ads_area_topic是用到的mysql表名;
2)dt , id, provinceName, regionDayAmouth, orderDayAmount, paymentDayAmount, areaCode;是ads_area_topic表的列名;
(2)GoodEntity
import com.baomidou.mybatisplus.annotation.TableId; import com.baomidou.mybatisplus.annotation.TableName; import lombok.Data; import java.io.Serializable; @Data @TableName("goods") public class GoodEntity implements Serializable { private static final long serialVersionUID = 1L; @TableId private Long id; private String name; private Integer num; }
(3)OrderDayCountEntity
import com.baomidou.mybatisplus.annotation.TableId; import com.baomidou.mybatisplus.annotation.TableName; import lombok.Data; import java.io.Serializable; @Data @TableName("ads_order_daycount") public class OrderDayCountEntity implements Serializable { private static final Long serialVersionUID = 1L; @TableId private String dt; private String orderCount; private String orderAmount; private String orderUsers; }
(4)ProductSaleTopNEntity
import com.baomidou.mybatisplus.annotation.TableId; import com.baomidou.mybatisplus.annotation.TableName; import lombok.Data; import java.io.Serializable; @Data @TableName("ads_product_sale_topN") public class ProductSaleTopNEntity implements Serializable { private static final Long serialVersionUID = 1L; @TableId private String dt; private String skuId; private String paymentAmount; }
(5)UserActionCountEntity
import com.baomidou.mybatisplus.annotation.TableField; import com.baomidou.mybatisplus.annotation.TableName; import lombok.Data; import javax.print.DocFlavor; import java.io.Serializable; @Data @TableName("ads_user_action_convert_day") public class UserActionCountEntity implements Serializable { private static final Long serialVersionUID = 1L; @TableField private String dt; private String homeCount; private String goodDetailCount; private String home2goodDetailConvertRatio; private String cartCount; private String goodDetail2cartConvertRatio; private String orderCount; private String cart2orderConvertRatio; private String paymentAmount; private String order2paymentConvertRatio; }
4.4.2dao

4.5测试
1)点击启动项目
2)启动成功样式
3)进入浏览器,测试接口
http://localhost:8080/areatopic/list http://localhost:8080/goods/list http://localhost:8080/orderdaycount/list http://localhost:8080/productsaletopN/list http://localhost:8080/useractioncount/list
注:
注意查看数据,都出现数据说明上面的代码没有问题!
如果有数据为空,先检查mysql数据库的数据有没有问题,没有问题再检查相应的entity的代码;
注意,如果数据库表的列名中有下划线,entity中下划线的后一位要用大写,不能用下划线;
比如:
id_user --------->idUser
gmall_ip_use -------------->gmallIpUse
五、前端代码编写
5.1准备
下载echarts.min.js,jquery-3.5.1.min.js.china.js
1)通过以下官网可以找到:
下载 - Apache ECharts
Download jQuery | jQuery
jquery下载所有版本(实时更新)
2)知道大家下载麻烦,我已经准备了好了,内含用到的css!免费下载哦!
echarts,jQuery文件-Javascript文档类资源-CSDN下载
5.2创建包
按照下面结构创建相应的文件和文件夹;
5.3代码编写
5.3.1配置静态资源访问
在properties.yml中添加
resources: web: resources: static-locations: classpath:/templates/, classpath:/static/
5.3.2在templates目录下创建HTML文件
k.html
柱状图
pie.html
饼状图
index.html
柱状图
line.html
ECharts
map.html
地图
bar.html
虚拟柱状图
bar-trend.html
柱状图
bar-negative.html
柱状图
endindex.html
数据仓库可视化展示
销售环
商品销售额统计
销量统计
数据仓库可视化展示
虚拟消费
收益情况
5.4测试
1)运行项目
2)进入浏览器
http://localhost:8080/endindex.html
说明:为了偷懒,只有pie.html, index.html, line.html调用了mysql的数据,其他的数据是手敲的。
注:
http://localhost:8080/加上HTML的文件名都能够查看相应的图!
要码源的私聊我
