This CS420 Object-Oriented Design project is for a business that handles assigning claims to contractors. I built in one day with AI assistance and zero Spring Boot experience. Front-end design was kept minimal to focus on core functionality. A production version would also integrate a claims management module.
./mvnw spring-boot:run then open in a browser page http://localhost:8080/
Frontend: React (or plain HTML) interface for associates to manage contractors and claims.
Backend: Spring Boot REST API (Java) running on a single Amazon EC2 instance.
Storage:
- SQLite database stored as a single file on the EC2 instance (e.g., /var/app/data/app.db) for contractor and claim data.
- Local file system (e.g., /var/app/uploads/) for storing contractor documents and photos.
Authentication: Basic authentication managed by Spring Security (no external identity provider).
Notifications: Email notifications sent using Spring Mail with SMTP (e.g., Gmail, AWS SES SMTP endpoint, or a local mail server).
Deployment:
- Spring Boot packaged as a JAR and run as a systemd service on EC2.
- Nginx (optional) configured as a reverse proxy with HTTPS.
Monitoring & Logging:
- application logs stored locally (/var/log/app.log).
- basic EC2 monitoring through AWS CloudWatch agent.
Backup: Periodic backup of the SQLite file and uploads folder.
Purpose: Maintain contractor profiles and service coverage.
Features:
- Add, edit, deactivate contractors.
- Track coverage areas (zip codes).
- Upload and view related documents.
Database Notes:
- SQLite stores all contractor and claim data in a single file.
- No separate DB server is required.
- Easy to backup by simply copying the .db file.
Purpose: Manage contractor claims.
Features:
- Add, edit, and close claims.
- Attach related documents or images.
- Query claims by contractor or status.
Database Notes:
- Stored in the same SQLite file.
- Supports standard SQL queries
