系统说明

对于BBS论坛系统来说,最主要的功能就是用户浏览帖子、发布帖子以及回复帖子。同时考虑用户所发布帖子的内容需要健康且合法,这就需要管理员加强对帖子的审核。如果用户想要在论坛发布帖子,前提是需要注册且处于登录状态。此外,为了便于从内容上对帖子加以区分,方便管理员对帖子的管理,还需要将论坛分为多个版块。还需要将用户划分为不同级别,根据用户级别的不同在论坛中为用户分配不同的权限,以进一步加强对论坛的管理。

综上,论坛既要实现对于帖子的管理,又要实现对于用户的管理,还要兼顾到各个功能模块之间的协调合作,共同完成BBS论坛系统的业务需求。下面采用UML用例模型对系统功能需求进行分析。

构建UML用例模型的第一步是确定模型中的使用者有哪些,确定使用者的原则有:谁是系统的维护者、谁是系统的参与者等。一般维护者处于系统内部,对系统有绝对的控制权;而参与者一般都位于系统的外部,处于系统的控制之外。

经过对BBS论坛系统的分析,可以确定本系统用例模型有二种,用户(用户分为游客和注册用户)和系统管理员。下面分别对这三个角色的功能进行描述:

1)用户

用户分为游客和注册用户,其中游客只能浏览论坛公共部分的内容,还可以注册成为论坛用户;注册用户则可以登录论坛、搜索帖子、发帖、回帖和查看个人中心。用户主要功能如下(图3-1为用

2)系统管理员

系统管理员主要负责系统的后台管理工作,主要功能如下(图3-2为系统管理员用例图):

  1. 用户管理;
  2. 帖子管理;
  3. 版块管理;
  4. 公告管理;
  5. 帮助管理;

图3-2 系统管理员用例图

确定了用户用例模型和管理员用例模型后,就可以构建BBS论坛系统的用例模型,整个系统的用例图如图3-3系统总体用例图所示:

环境需要

1.运行环境:最好是java jdk 1.8,我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境:IDEA,Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境:Tomcat 7.x,8.x,9.x版本均可
4.硬件环境:windows 7/8/10 1G内存以上;或者 Mac OS; 
5.数据库:MySql 5.7版本;
6.是否Maven项目:否;

技术栈

1. 后端:Spring+SpringMVC+Mybatis
2. 前端:JSP+CSS+JavaScript+jQuery

使用说明

1. 使用Navicat或者其它工具,在mysql中创建对应名称的数据库,并导入项目的sql文件;
2. 使用IDEA/Eclipse/MyEclipse导入项目,Eclipse/MyEclipse导入时,若为maven项目请选择maven;
若为maven项目,导入成功后请执行maven clean;maven install命令,然后运行;
3. 将项目中springmvc-servlet.xml配置文件中的数据库配置改为自己的配置;
4. 运行项目,在浏览器中输入http://localhost:8080/ 登录
