基于JSP实现的项目管理平台系统

2022-01-14 09:06:55 阅读：125 来源： 互联网

标签：基于 String rs 项目管理 req JSP import servlet id

项目编号：BS-XX-022

本系统基于JSP，SERVLET实现开发，前端采用layui框架实现，数据库采用MYSQL，开发工具采用IDEA或ECLIPSE。主要实现如下功能：

从管理员角度看:

用户登入系统后，可以修改管理员的密码。同时具有以下功能：

1、管理员可以管理具体项目信息。

2、管理员可以管理项目经费信息。

3、管理员可以管理项目资源信息。

4、管理员可以管理项目进度信息。

5、管理员可以管理项目成果信息。

部分展示功能如下：admin / admin

http://localhost/login.jsp

后台管理主界面

项目信息管理

项目经费管理

项目资源管理

项目进度管理

项目成果管理

本项目基本功能完整，运行无误，适合做毕业设计使用。
