# 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 { /* ... */ }
|
||||
```
|
||||
|
||||

## 🔧 Key Features
|
||||
|
||||
### 1. **Dependency Injection (CDI)**
|
||||
- Type-safe injection with `@Inject`
|
||||
- Singleton services with `@Produces`
|
||||
- Configuration injection with `@ConfigProperty`
|
||||
|
||||
### 2. **Scheduled Tasks**
|
||||
- Cron-based scheduling with `@Scheduled`
|
||||
- Configurable via properties
|
||||
- No manual thread management
|
||||
|
||||
### 3. **REST API**
|
||||
- JAX-RS endpoints
|
||||
- JSON serialization
|
||||
- Error handling
|
||||
|
||||
### 4. **Health Checks**
|
||||
- Liveness probe (is app alive?)
|
||||
- Readiness probe (is app ready?)
|
||||
- Startup probe (has app started?)
|
||||
|
||||
### 5. **Configuration**
|
||||
- External configuration
|
||||
- Environment variable override
|
||||
- Type-safe config injection
|
||||
|
||||
### 6. **Container Ready**
|
||||
- Optimized Docker image
|
||||
- Fast startup (~0.5s)
|
||||
- Low memory (~50MB)
|
||||
- Health checks included
|
||||
|
||||
### 7. **Cloud Native**
|
||||
- Kubernetes manifests
|
||||
- Auto-scaling support
|
||||
- Ingress configuration
|
||||
- Persistent storage
