Project acquisition:
https://gitee.com/sinonfin/L-javaWebSha
1. Project design
1. Modular design
According to the result of demand analysis, the article publishing system is mainly divided into two sub-modules, the background management module and the front-end portal module, and each module contains sub-modules. Divided into the following modules
- Interface Design Module
- User Registration Module
- User Login Module
- Article Search Module
- User message module
- User Review Module
- User Information Management Module
- Function Management Section
- User Management Module
- Announcement Management Module
- Article Management Module
- Comment Management Module
- Message management module
- Admin Management Module
2. Realize the effect
There are many functions, and the seniors will not show them one by one here.
