GT7 Sync

GT7 Sync

GT7 Sync scrapes the official Gran Turismo 7 website to import car and track master data into the application.

Overview

Component	Class	Purpose
Scraper	Gt7ScraperService	Fetches and parses data from gran-turismo.com
Sync	Gt7SyncService	Merges scraped data with the local database
Controller	Gt7SyncController	Admin UI for triggering sync operations
Preview	Gt7SyncPreview	Preview model for review before import

Car Scraping

• Source: https://www.gran-turismo.com/gb/gt7/carlist/
• Parses JavaScript bundles embedded in the page to extract:
  • Car names
  • Manufacturer mapping
  • GT7 internal IDs
  • Car images
• Handles the site's dynamic rendering by parsing the JS data structures directly

Track Scraping

• Source: https://www.gran-turismo.com/gb/gt7/tracklist/
• Two scraping modes:

Mode	Speed	Data
Fast	Quick	Track names and IDs only
Full	Slower	Names, IDs, and track images

Image Download

• Images are downloaded in parallel using CompletableFuture for performance
• Stored locally in the application's upload directory
• Referenced by the Car and Track entities

Sync Workflow

1. Trigger sync from the admin UI (GT7 Sync page)
2. Preview mode: Review scraped data before committing
   • Shows new cars/tracks to be added
   • Shows existing entries that will be updated
3. Duplicate detection: Matches by GT7 ID to avoid duplicates
4. Execute import: Confirmed changes are persisted to the database

GT7 ID Tracking

Each car and track stores its GT7 ID, enabling:

• Reliable duplicate detection across syncs
• Stable references even if names change on the source website
• Incremental updates (only new/changed entries are imported)

Demo Profile

When running with the dev,demo profile combination:

./mvnw spring-boot:run -Dspring-boot.run.profiles=dev,demo

The application automatically imports all GT7 cars and tracks (with images) at startup. This provides a fully populated database for manual testing without requiring a manual sync trigger.
