## 前言 ##

今天学长向大家分享一个 java web 毕设 项目:

**文章发布系统的设计与实现**

--------------------

## 一、项目设计 ##

### 1. 模块设计 ###

根据需求分析的结果，文章发布系统主要划分两个子模块后台管理模块，前台门户模块，各模块又包含子模块。分为以下几个模块

*  界面设计模块
 *  用户注册模块
 *  用户登录模块
 *  文章搜索模块
 *  用户留言模块
 *  用户评论模块
 *  用户信息管理模块
 *  功能管理部分
 *  用户管理模块
 *  公告管理模块
 *  文章管理模块
 *  评论管理模块
 *  留言管理模块
 *  管理员管理模块

### 2. 实现效果 ###
