讀萬(wàn)卷書不如行萬(wàn)里路，只學(xué)書上的理論是遠(yuǎn)遠(yuǎn)不夠的，只有在實(shí)戰(zhàn)中才能獲得能力的提升，本篇文章手把手帶你用java+SSM+mysql+maven+tomcat實(shí)現(xiàn)一個(gè)校園二手市場(chǎng)系統(tǒng),大家可以在過(guò)程中查缺補(bǔ)漏，提升水平

一、項(xiàng)目簡(jiǎn)述（ +IW文檔）

功能：本系統(tǒng)分用戶前臺(tái)和管理員后臺(tái)。本系統(tǒng)用例模型有三種，分別是游客、注冊(cè)用戶和系統(tǒng)管理員。下面分別對(duì)這三個(gè)角色的功能進(jìn)行描述： 1）誕游客是未注冊(cè)的用戶，他們可以瀏覽物物品，可以搜索物品，如需購(gòu)買物品，必須先注冊(cè)成為網(wǎng)站用戶。游客主要功觸嚇： a.瀏覽物品 b.搜索物品 c.注冊(cè)成為網(wǎng)站用戶 2）注冊(cè)用戶注冊(cè)用戶是經(jīng)過(guò)網(wǎng)站合法認(rèn)證的用戶，登錄網(wǎng)站后可以瀏覽物品、搜索物品、發(fā)布物品、關(guān)注物品、購(gòu)買物品和查看個(gè)人中心。 3）系統(tǒng)管理員系統(tǒng)管理員主要負(fù)責(zé)系統(tǒng)的后臺(tái)管理工作，主要功能如下：用戶管理，商品管理等等。

二、項(xiàng)目運(yùn)行

環(huán)境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe （ IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持）

項(xiàng)目技術(shù)： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。
