目录
由于最近参加一些其他活动，没有学习更新电商项目，今天继续。
本篇文章将介绍用户访问session分析-session聚合统计之计算统计结果可视化。
由于前面的项目创建的时候没有考虑到可视化可能遇到的问题，后面发现写网页的时候有问题，所以我就将项目从新迁移了一下。
创建WEB项目
创建步骤详情参考：IntelliJ IDEA创建maven web项目
完善后续：将前面所写的代码迁移过来。
可视化结果
测试可视化环境
在数据库中创建一张Goods表
create table goods( id int auto_increment primary key, name varchar(255), price int(4), sales int(11), stock int(11), detail varchar(255) );
插入一些数据
insert into goods(name,price,sales,stock,detail) values('短袖',88,600,150,'潮流时尚大方'); insert into goods(name,price,sales,stock,detail) values('茶叶',50,500,500,'健康的生活'); insert into goods(name,price,sales,stock,detail) values('矿泉水',3,1000,1000,'大自然的搬运工'); insert into goods(name,price,sales,stock,detail) values('香飘飘',3,200,500,'绕地球一周'); insert into goods(name,price,sales,stock,detail) values('王老吉',4,400,700,'红罐凉茶');

创建目录servlet

编写网页
目录结构
jsp目录下
goodssales.jsp //展示结果
