1. Project overview:
This project develops and implements a job-hunting website based on Springboot. The system is divided into front-end job-hunting and back-end data management. It is mainly divided into four corners: administrator, job seeker, company administrator, and company HR. Different roles enter the system and have different functional operations. User identity can be set in the background management. The system functions are complete, the interface is beautiful and generous, and it is suitable for graduation design.
Operating environment:
Development tools: IDEA or ECLIPSE
Database: MYSQL+REDIS
Development technology: Springboot+mybatis+mybatisPlus+shiro
Front-end development: AJAX+Jquery+layui
2.1 Functional requirements
2.1.1 System Division
2.1.1.1 User role division
- job seeker
A user who logs in to this website can retrieve and view the companies that the website has settled in and the job information posted by them, create their own resumes, and contact recruiters.
- Applicants
2.1、HR
A certain HR under the company can post new jobs and cancel the job postings posted by themselves
2.2, company administrator
Company administrator, fill in the relevant information of the company and become this role after entering the website, and can manage all positions published by the company, as well as manage all employees
3. Administrator
You can view relevant data on the site, manage private messages, systems, and settings.
2.1.1.2 Use case diagram and description of foreground service
- Recruiter Features
- View personal information: View the basic information and modification of your account
- Change Password: Change the login password of your account
- Private message: private message with job seekers
- Company entry: If it is the first time to log in to the website, the user can enter the company information, enter the website, and then post a job
