# Quarkus Implementation Complete ✅
## Summary
The Troostwijk Auction Monitor has been fully integrated with **Quarkus Framework** for production-ready deployment with enterprise features.
---
## 🎯 What Was Added
### 1. **Quarkus Dependencies** (pom.xml)
```xml
<!-- Core Quarkus -->
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-arc</artifactId> <!-- CDI/DI -->
</dependency>
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-rest-jackson</artifactId> <!-- REST API -->
</dependency>
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-scheduler</artifactId> <!-- Cron Scheduling -->
</dependency>
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-smallrye-health</artifactId> <!-- Health Checks -->
</dependency>
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-config-yaml</artifactId> <!-- YAML Config -->
</dependency>
```
### 2. **Configuration** (application.properties)
```properties
# Application
quarkus.application.name=troostwijk-scraper
quarkus.http.port=8081
# Auction Monitor Configuration
auction.database.path=C:\\mnt\\okcomputer\\output\\cache.db
auction.images.path=C:\\mnt\\okcomputer\\output\\images
auction.notification.config=desktop
# YOLO Models
auction.yolo.config=models/yolov4.cfg
auction.yolo.weights=models/yolov4.weights
auction.yolo.classes=models/coco.names
# Workflow Schedules (Cron Expressions)
auction.workflow.scraper-import.cron=0 */30 * * * ? # Every 30 min
auction.workflow.image-processing.cron=0 0 * * * ? # Every 1 hour
auction.workflow.bid-monitoring.cron=0 */15 * * * ? # Every 15 min
auction.workflow.closing-alerts.cron=0 */5 * * * ? # Every 5 min
# Scheduler
quarkus.scheduler.enabled=true
# Health Checks
quarkus.smallrye-health.root-path=/health
```
### 3. **Quarkus Scheduler** (QuarkusWorkflowScheduler.java)
Replaced manual `ScheduledExecutorService` with Quarkus `@Scheduled`:
```java
@ApplicationScoped
public class QuarkusWorkflowScheduler {
@Inject DatabaseService db;
@Inject NotificationService notifier;
@Inject ObjectDetectionService detector;
@Inject ImageProcessingService imageProcessor;
// Workflow 1: Every 30 minutes
@Scheduled(cron = "{auction.workflow.scraper-import.cron}")
void importScraperData() { /* ... */ }
// Workflow 2: Every 1 hour
@Scheduled(cron = "{auction.workflow.image-processing.cron}")
void processImages() { /* ... */ }
// Workflow 3: Every 15 minutes
@Scheduled(cron = "{auction.workflow.bid-monitoring.cron}")
void monitorBids() { /* ... */ }
// Workflow 4: Every 5 minutes
@Scheduled(cron = "{auction.workflow.closing-alerts.cron}")
void checkClosingTimes() { /* ... */ }
}
```
### 4. **CDI Producer** (AuctionMonitorProducer.java)
Centralized service creation with dependency injection:
```java
@ApplicationScoped
public class AuctionMonitorProducer {
@Produces @Singleton
public DatabaseService produceDatabaseService(
@ConfigProperty(name = "auction.database.path") String dbPath) {
DatabaseService db = new DatabaseService(dbPath);
db.ensureSchema();
return db;
}
@Produces @Singleton
public NotificationService produceNotificationService(
@ConfigProperty(name = "auction.notification.config") String config) {
return new NotificationService(config, "");
}
@Produces @Singleton
public ObjectDetectionService produceObjectDetectionService(...) { }
@Produces @Singleton
public ImageProcessingService produceImageProcessingService(...) { }
}
```
### 5. **REST API** (AuctionMonitorResource.java)
Full REST API for monitoring and control:
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/monitor/status` | GET | Get current status |
| `/api/monitor/statistics` | GET | Get detailed statistics |
| `/api/monitor/trigger/scraper-import` | POST | Trigger scraper import |
| `/api/monitor/trigger/image-processing` | POST | Trigger image processing |
| `/api/monitor/trigger/bid-monitoring` | POST | Trigger bid monitoring |
| `/api/monitor/trigger/closing-alerts` | POST | Trigger closing alerts |
| `/api/monitor/auctions` | GET | List auctions |
| `/api/monitor/auctions?country=NL` | GET | Filter auctions by country |
| `/api/monitor/lots` | GET | List active lots |
| `/api/monitor/lots/closing-soon` | GET | Lots closing soon |
| `/api/monitor/lots/{id}/images` | GET | Get lot images |
| `/api/monitor/test-notification` | POST | Send test notification |
### 6. **Health Checks** (AuctionMonitorHealthCheck.java)
Kubernetes-ready health probes:
```java
@Liveness // /health/live
public class LivenessCheck implements HealthCheck {
public HealthCheckResponse call() {
return HealthCheckResponse.up("Auction Monitor is alive");
}
}
@Readiness // /health/ready
public class ReadinessCheck implements HealthCheck {
@Inject DatabaseService db;
public HealthCheckResponse call() {
var auctions = db.getAllAuctions();
return HealthCheckResponse.named("database")
.up()
.withData("auctions", auctions.size())
.build();
}
}
@Startup // /health/started
public class StartupCheck implements HealthCheck { /* ... */ }
```
### 7. **Docker Support**
#### Dockerfile (Optimized for Quarkus fast-jar)
```dockerfile
# Build stage

EXPOSE 8081
HEALTHCHECK CMD wget --spider http://localhost:8081/health/live
ENTRYPOINT ["java", "-jar", "/app/quarkus-run.jar"]
```

- AUCTION_NOTIFICATION_CONFIG=desktop
healthcheck:
test: ["CMD", "wget", "--spider", "http://localhost:8081/health/live"]
interval: 30s
restart: unless-stopped
```
### 8. **Kubernetes Deployment**
Full Kubernetes manifests:
- **Namespace** - Isolated environment
- **PersistentVolumeClaim** - Data storage
- **ConfigMap** - Configuration
- **Secret** - Sensitive data (SMTP credentials)
- **Deployment** - Application pods
- **Service** - Internal networking
