Java 實戰項目之小說在線閱讀系統的實現流程

Posted on by

一、項目簡述

功能包括(管理員和遊客角色)：

1:用戶及主要操作功能 遊客可以瀏覽網站的主頁，但是需要註冊為會員後部分小 說才能對網絡小說進免費行閱讀或閱讀。用戶可以收藏書 架，留言評論，上次閱讀，閱讀歷史，章節選擇等等功 能。

2:管理模塊 網絡小說管理模塊包括不同網絡小說類別的添加，刪除以 及網絡小說的上傳，刪除管理。可以包括武俠小書，都市 言情，穿越小書等各個類等等功能。

二、項目運行

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

項目技術： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax等等。

讀者操作業務控制層：
