?簡(jiǎn)介：Java領(lǐng)域優(yōu)質(zhì)創(chuàng)作者、Java項(xiàng)目、學(xué)習(xí)資料、技術(shù)互助
文末獲取源碼
項(xiàng)目介紹
本項(xiàng)目為小程序商城系統(tǒng)前后臺(tái)，前臺(tái)為普通會(huì)員用戶(hù)登錄，后臺(tái)為管理員登錄；
程序功能：
1.小程序前臺(tái)：用戶(hù)注冊(cè)登錄、首頁(yè)、輪播圖、新品推薦、分類(lèi)、購(gòu)物車(chē)、我的訂單。
2.網(wǎng)站后臺(tái)：管理員登錄、用戶(hù)管理、商品類(lèi)別管理、商品管理、訂單管理、公告管理；
環(huán)境需要
1.運(yùn)行環(huán)境：最好是java jdk 1.8，我們?cè)谶@個(gè)平臺(tái)上運(yùn)行的。其他版本理論上也可以。
2.IDE環(huán)境：IDEA，Eclipse,Myeclipse都可以。推薦IDEA;
3.tomcat環(huán)境：Tomcat 7.x,8.x,9.x版本均可
4.硬件環(huán)境：windows 7/8/10 1G內(nèi)存以上；或者 Mac OS；
5.數(shù)據(jù)庫(kù)：MySql 5.7版本；
6.是否Maven項(xiàng)目: 否；
技術(shù)棧
1. 后端：spring+struts+hibernate
2. 前端：JSP+css+javascript+jquery
使用說(shuō)明
后臺(tái)運(yùn)行：
1. 使用Navicat或者其它工具，在mysql中創(chuàng)建對(duì)應(yīng)名稱(chēng)的數(shù)據(jù)庫(kù)，并導(dǎo)入項(xiàng)目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse導(dǎo)入項(xiàng)目，Eclipse/MyEclipse導(dǎo)入時(shí)，若為maven項(xiàng)目請(qǐng)選擇maven;
若為maven項(xiàng)目，導(dǎo)入成功后請(qǐng)執(zhí)行maven clean;maven install命令，然后運(yùn)行；
3. 將項(xiàng)目中config/jdbc.properties配置文件中的數(shù)據(jù)庫(kù)配置改為自己的配置;
4. 運(yùn)行項(xiàng)目，在瀏覽器中輸入http://localhost:8080/shop
管理員：admin/111111
前臺(tái)小程序運(yùn)行：
1.使用微信開(kāi)發(fā)者工具導(dǎo)入項(xiàng)目；
2.導(dǎo)入成功后編譯運(yùn)行；
3.運(yùn)行成功后登錄賬號(hào)；
