# STOMP Messaging Integration
|
||||
# VOTIANLT Realtime & Photo Upload API
|
||||
|
||||
Die Anwendung unterstützt jetzt STOMP (Simple Text Oriented Messaging Protocol) für die Kommunikation mit externen Apps über WebSocket-Verbindungen.
|
||||
This document describes how mobile/Flutter apps can interact with the backend via STOMP (WebSocket) and how to upload photos via HTTP POST (new flow).
|
||||
|
||||
## Übersicht
|
||||
## 1) STOMP Overview
|
||||
|
||||
Das System bietet folgende STOMP-Funktionalitäten:
|
||||
- Connect to one of the WebSocket endpoints:
|
||||
- `/ws` (SockJS fallback supported)
|
||||
- `/websocket` (native WebSocket)
|
||||
- `/stomp` (native WebSocket, alternate path)
|
||||
- Application destination prefix: `/app`
|
||||
- Broker destinations:
|
||||
- Broadcast: `/topic/...`
|
||||
- User specific: `/user/queue/...`
|
||||
|
||||
### WebSocket-Endpunkte
|
||||
Examples:
|
||||
- Send a generic message: send to `/app/message`, receive on `/topic/messages`
|
||||
- Job updates: send to `/app/job/status`, receive on `/topic/job-updates`
|
||||
- Device locations: send to `/app/device/location`, receive on `/topic/device-locations`
|
||||
- Task updates (broadcast): `/topic/task-updates`
|
||||
- Task specific topic: `/topic/tasks/{taskId}`
|
||||
|
||||
- **`/ws`** - STOMP-Endpunkt mit SockJS-Fallback-Unterstützung
|
||||
- **`/websocket`** - Reiner WebSocket-Endpunkt ohne SockJS
|
||||
## 2) Photo Task – New HTTP Upload Flow
|
||||
|
||||
### Nachrichtendestinationen
|
||||
In the future, photos for a PHOTO task must NOT be embedded in the STOMP message anymore. Instead, upload the photos via HTTP POST and only send the task-completion event via STOMP without large payloads.
|
||||
|
||||
#### Eingehende Nachrichten (Client → Server)
|
||||
- **`/app/message`** - Allgemeine Nachrichten
|
||||
- **`/app/job/status`** - Job-Status-Updates
|
||||
- **`/app/device/location`** - Gerätestandort-Updates
|
||||
- **`/app/auth/login`** - Anmeldung eines App-Users (Payload: { email, password })
|
||||
### Endpoint
|
||||
|
||||
#### Ausgehende Nachrichten (Server → Client)
|
||||
- **`/topic/messages`** - Broadcast aller allgemeinen Nachrichten
|
||||
- **`/topic/job-updates`** - Job-Status-Updates für alle Abonnenten
|
||||
- **`/topic/device-locations`** - Gerätestandort-Updates
|
||||
- **`/topic/broadcasts`** - System-weite Broadcast-Nachrichten
|
||||
- **`/queue/notifications`** - Benutzerspezifische Benachrichtigungen
|
||||
- URL: `POST /api/tasks/{taskId}/photos`
|
||||
- Purpose: Upload one or many photos for a task of type `PHOTO`.
|
||||
- Path params:
|
||||
- `taskId` (required): The MongoDB ObjectId of the task.
|
||||
- Auth: (same as your app uses today; if you have a session/cookie or token, include it accordingly)
|
||||
- CORS: Enabled for `*` by default on this controller.
|
||||
|
||||
## Verwendung für Apps
|
||||
### Content Types (choose one)
|
||||
|
||||
### 1. Verbindung aufbauen
|
||||
1) Multipart form data (recommended for binary images)
|
||||
|
||||
```javascript
|
||||
// Mit SockJS
|
||||
const socket = new SockJS('http://192.168.180.196:8080/ws');
|
||||
const stompClient = Stomp.over(socket);
|
||||
- `Content-Type: multipart/form-data`
|
||||
- Fields:
|
||||
- `files`: one or multiple image files (repeat the field for multiple images)
|
||||
- `completedBy` (optional): username/id of the completing user
|
||||
- `note` (optional): any note (currently stored on the task when you mark it as completed via STOMP)
|
||||
|
||||
// Oder mit nativem WebSocket (WICHTIG: ws:// verwenden, nicht http://)
|
||||
const socket = new WebSocket('ws://192.168.180.196:8080/websocket');
|
||||
const stompClient = Stomp.over(socket);
|
||||
Example (curl):
|
||||
|
||||
```bash
|
||||
curl -X POST "http://localhost:8080/api/tasks/66f5c2f1a3b6e27a1a234567/photos" \
|
||||
-H "Content-Type: multipart/form-data" \
|
||||
-F "files=@/path/to/photo1.jpg" \
|
||||
-F "files=@/path/to/photo2.jpg" \
|
||||
-F "completedBy=driver01" \
|
||||
-F "note=Anlieferung dokumentiert"
|
||||
```
|
||||
|
||||
### Flutter/Dart STOMP Client
|
||||
2) JSON with base64 strings (kept for compatibility)
|
||||
|
||||
**Für Flutter-Apps verwenden Sie diese Konfiguration:**
|
||||
|
||||
```dart
|
||||
import 'package:stomp_dart_client/stomp.dart';
|
||||
import 'package:stomp_dart_client/stomp_config.dart';
|
||||
import 'package:stomp_dart_client/stomp_frame.dart';
|
||||
import 'dart:convert';
|
||||
|
||||
// WICHTIG: Verwenden Sie ws:// für WebSocket-Verbindungen, NICHT http://
|
||||
final stompClient = StompClient(
|
||||
config: StompConfig(
|
||||
url: 'ws://192.168.180.196:8080/websocket', // Beachten Sie ws:// statt http://
|
||||
onConnect: onConnectCallback,
|
||||
onWebSocketError: (dynamic error) => print('WebSocket Error: $error'),
|
||||
onStompError: (StompFrame frame) => print('Stomp Error: ${frame.body}'),
|
||||
onDisconnect: (StompFrame frame) => print('Disconnected'),
|
||||
// Heartbeat-Konfiguration
|
||||
heartbeatIncoming: Duration(seconds: 20),
|
||||
heartbeatOutgoing: Duration(seconds: 20),
|
||||
),
|
||||
);
|
||||
|
||||
void onConnectCallback(StompFrame frame) {
|
||||
print('Connected to STOMP server');
|
||||
|
||||
// Nachrichten abonnieren
|
||||
stompClient.subscribe(
|
||||
destination: '/topic/messages',
|
||||
callback: (StompFrame frame) {
|
||||
print('Received message: ${frame.body}');
|
||||
},
|
||||
);
|
||||
}
|
||||
|
||||
// Verbindung herstellen
|
||||
stompClient.activate();
|
||||
|
||||
// Nachricht senden
|
||||
void sendMessage(String content) {
|
||||
stompClient.send(
|
||||
destination: '/app/message',
|
||||
body: jsonEncode({
|
||||
'content': content,
|
||||
'sender': 'FlutterApp',
|
||||
}),
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Alternative Endpunkte für Flutter:**
|
||||
Falls Probleme mit `/websocket` auftreten, versuchen Sie:
|
||||
- `ws://192.168.180.196:8080/stomp` (zusätzlicher Endpunkt)
|
||||
- `ws://192.168.180.196:8080/ws` (SockJS-Endpunkt ohne SockJS-Protokoll)
|
||||
|
||||
### 2. Verbindung herstellen
|
||||
|
||||
```javascript
|
||||
stompClient.connect({}, function(frame) {
|
||||
console.log('Verbunden: ' + frame);
|
||||
|
||||
// Nachrichten abonnieren
|
||||
stompClient.subscribe('/topic/messages', function(message) {
|
||||
console.log('Nachricht erhalten:', JSON.parse(message.body));
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### 3. Nachrichten senden
|
||||
|
||||
```javascript
|
||||
// Allgemeine Nachricht senden
|
||||
stompClient.send('/app/message', {}, JSON.stringify({
|
||||
content: 'Hallo vom App',
|
||||
sender: 'MobileApp'
|
||||
}));
|
||||
|
||||
// Job-Status-Update senden
|
||||
stompClient.send('/app/job/status', {}, JSON.stringify({
|
||||
jobId: '12345',
|
||||
status: 'IN_PROGRESS',
|
||||
progress: 75
|
||||
}));
|
||||
|
||||
// Gerätestandort senden
|
||||
stompClient.send('/app/device/location', {}, JSON.stringify({
|
||||
deviceId: 'device-001',
|
||||
latitude: 52.5200,
|
||||
longitude: 13.4050,
|
||||
accuracy: 10
|
||||
}));
|
||||
|
||||
// Anmeldung eines App-Users
|
||||
// Zuerst die Antwort-Warteschlange abonnieren (user-spezifisch)
|
||||
const authSubscription = stompClient.subscribe('/user/queue/auth', function(message) {
|
||||
const resp = JSON.parse(message.body);
|
||||
console.log('Login-Antwort:', resp);
|
||||
});
|
||||
|
||||
// Login-Request senden
|
||||
stompClient.send('/app/auth/login', {}, JSON.stringify({
|
||||
email: 'user@example.com',
|
||||
password: 'geheimesPasswort'
|
||||
}));
|
||||
```
|
||||
|
||||
## Backend-Integration
|
||||
|
||||
### Programmatische Nachrichten senden
|
||||
|
||||
```java
|
||||
@Autowired
|
||||
private MessageController messageController;
|
||||
|
||||
// Benachrichtigung an spezifischen Benutzer
|
||||
messageController.sendNotificationToUser("username", "Neue Aufgabe verfügbar");
|
||||
|
||||
// Broadcast-Nachricht an alle
|
||||
messageController.sendBroadcastMessage("Systemwartung in 10 Minuten");
|
||||
```
|
||||
|
||||
## Zeroconf (mDNS) Veröffentlichung
|
||||
|
||||
Die Anwendung veröffentlicht die STOMP-Schnittstelle via Zeroconf (DNS-SD/mDNS), sofern verfügbar. Es wird der Service-Typ `_stomp._tcp.local.` mit folgenden TXT-Records publiziert:
|
||||
- path = Pfad für SockJS-Endpoint (Standard: /ws)
|
||||
- websocket = Pfad für nativen WebSocket (Standard: /websocket)
|
||||
- protocol = "stomp"
|
||||
|
||||
Clients können per Bonjour/mDNS nach `_stomp._tcp` suchen und erhalten Port und Metadaten.
|
||||
|
||||
Hinweise:
|
||||
- Die Implementierung nutzt JmDNS, falls die Bibliothek auf dem Klassenpfad vorhanden ist. In Umgebungen ohne JmDNS bleibt Zeroconf stillschweigend deaktiviert (es wird ein Hinweis im Log ausgegeben).
|
||||
- Konfigurierbare Properties:
|
||||
- app.zeroconf.enabled (default: true)
|
||||
- app.zeroconf.serviceName (default: votianlt-stomp)
|
||||
- app.stomp.wsPath (default: /ws)
|
||||
- app.stomp.websocketPath (default: /websocket)
|
||||
|
||||
## Konfiguration
|
||||
|
||||
Die STOMP-Konfiguration befindet sich in:
|
||||
- **`WebSocketConfig.java`** - WebSocket und STOMP-Konfiguration
|
||||
- **`MessageController.java`** - Nachrichtenbehandlung
|
||||
- **`application.properties`** - Zusätzliche WebSocket-Einstellungen
|
||||
|
||||
### Wichtige Konfigurationsparameter
|
||||
|
||||
```properties
|
||||
# Nachrichtenpuffergröße
|
||||
spring.websocket.servlet.max-text-message-buffer-size=8192
|
||||
spring.websocket.servlet.max-binary-message-buffer-size=8192
|
||||
|
||||
# STOMP aktivieren
|
||||
spring.websocket.stomp.enabled=true
|
||||
|
||||
# Heartbeat-Einstellungen
|
||||
spring.websocket.stomp.heartbeat.outgoing=10000
|
||||
spring.websocket.stomp.heartbeat.incoming=10000
|
||||
```
|
||||
|
||||
## Sicherheitshinweise
|
||||
|
||||
- WebSocket-Verbindungen verwenden die gleiche Authentifizierung wie die Web-Anwendung
|
||||
- Nachrichten werden automatisch mit Zeitstempel versehen
|
||||
- Alle Nachrichten werden in JSON-Format verarbeitet
|
||||
|
||||
## Testing
|
||||
|
||||
Zum Testen der STOMP-Funktionalität können Sie:
|
||||
1. Eine WebSocket-Client-Bibliothek verwenden
|
||||
2. Browser-Entwicklertools für WebSocket-Verbindungen nutzen
|
||||
3. Spezialisierte STOMP-Testing-Tools einsetzen
|
||||
|
||||
Die Implementierung ist vollständig und bereit für die Integration mit externen Apps.
|
||||
|
||||
## Neue STOMP-Schnittstelle: Task-Erledigung melden
|
||||
|
||||
Mit dieser Schnittstelle kann ein Client die Erledigung eines Tasks melden.
|
||||
|
||||
- Senden (Client → Server): `/app/task/completed`
|
||||
- Broadcasts (Server → Client):
|
||||
- Global: `/topic/task-updates`
|
||||
- Task-spezifisch: `/topic/tasks/{taskId}`
|
||||
|
||||
Payload (JSON):
|
||||
- `Content-Type: application/json`
|
||||
- Body:
|
||||
|
||||
```json
|
||||
{
|
||||
"taskId": "<MongoId als String>",
|
||||
"completedBy": "<optional: Name/ID des Ausführenden>",
|
||||
"note": "<optional: Kommentar>"
|
||||
}
|
||||
```
|
||||
|
||||
Antwort (Beispiel):
|
||||
|
||||
```json
|
||||
{
|
||||
"timestamp": "2025-09-05T09:25:00",
|
||||
"type": "taskCompletedAck",
|
||||
"success": true,
|
||||
"taskId": "...",
|
||||
"jobId": "...",
|
||||
"completed": true,
|
||||
"completedAt": "2025-09-05T09:25:00",
|
||||
"completedBy": "driver01",
|
||||
"note": "Übergabe erfolgreich",
|
||||
"event": "taskCompleted"
|
||||
"note": "Anlieferung dokumentiert",
|
||||
"photos": [
|
||||
"<base64-of-image-1>",
|
||||
"<base64-of-image-2>"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
JavaScript Beispiel:
|
||||
Example (curl):
|
||||
|
||||
```javascript
|
||||
// Abonnieren der globalen Updates
|
||||
stompClient.subscribe('/topic/task-updates', (frame) => {
|
||||
console.log('Task update:', JSON.parse(frame.body));
|
||||
});
|
||||
|
||||
// Abonnieren eines spezifischen Tasks
|
||||
stompClient.subscribe('/topic/tasks/' + taskId, (frame) => {
|
||||
console.log('Task-specific update:', JSON.parse(frame.body));
|
||||
});
|
||||
|
||||
// Task als erledigt melden
|
||||
stompClient.send('/app/task/completed', {}, JSON.stringify({
|
||||
taskId: taskId,
|
||||
completedBy: 'driver01',
|
||||
note: 'Übergabe erfolgreich'
|
||||
}));
|
||||
```bash
|
||||
curl -X POST "http://localhost:8080/api/tasks/66f5c2f1a3b6e27a1a234567/photos" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"completedBy":"driver01",
|
||||
"note":"Anlieferung dokumentiert",
|
||||
"photos":["iVBORw0KGgo...","iVBORw0KGgo..."]
|
||||
}'
|
||||
```
|
||||
|
||||
Flutter/Dart Beispiel:
|
||||
### Simple JSON endpoint (single photo per call)
|
||||
|
||||
```dart
|
||||
stompClient.subscribe(
|
||||
destination: '/topic/task-updates',
|
||||
callback: (frame) => print('Task update: ${frame.body}'),
|
||||
);
|
||||
- URL: `POST /api/photos`
|
||||
- Content-Type: `application/json`
|
||||
- Body:
|
||||
|
||||
stompClient.subscribe(
|
||||
destination: '/topic/tasks/$taskId',
|
||||
callback: (frame) => print('Task-specific update: ${frame.body}'),
|
||||
);
|
||||
|
||||
stompClient.send(
|
||||
destination: '/app/task/completed',
|
||||
body: jsonEncode({
|
||||
'taskId': taskId,
|
||||
'completedBy': 'driver01',
|
||||
'note': 'Übergabe erfolgreich',
|
||||
}),
|
||||
);
|
||||
```json
|
||||
{
|
||||
"taskId": "66f5c2f1a3b6e27a1a234567",
|
||||
"photo": "<base64-of-image>",
|
||||
"completedBy": "driver01",
|
||||
"note": "optional"
|
||||
}
|
||||
```
|
||||
|
||||
Hinweise:
|
||||
- `taskId` ist Pflicht. Bei ungültiger oder unbekannter `taskId` wird `success=false` zurückgegeben.
|
||||
- Der Server setzt `completed=true` und `completedAt` automatisch.
|
||||
- Zusätzlich zum globalen Broadcast wird ein task-spezifisches Event auf `/topic/tasks/{taskId}` versendet.
|
||||
- Multiple photos: call this endpoint multiple times (one image per request).
|
||||
|
||||
Example (curl):
|
||||
|
||||
```bash
|
||||
curl -X POST "http://localhost:8080/api/photos" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"taskId":"66f5c2f1a3b6e27a1a234567",
|
||||
"photo":"iVBORw0KGgo...",
|
||||
"completedBy":"driver01",
|
||||
"note":"Anlieferung dokumentiert"
|
||||
}'
|
||||
```
|
||||
|
||||
### Response
|
||||
|
||||
Both content types return the same JSON structure on success:
|
||||
|
||||
```json
|
||||
{
|
||||
"timestamp": "2025-09-13T21:27:00",
|
||||
"type": "photoUploadAck",
|
||||
"success": true,
|
||||
"photoId": "66f5c400b1a1b05b1c123abc",
|
||||
"photosCount": 2,
|
||||
"taskId": "66f5c2f1a3b6e27a1a234567",
|
||||
"jobId": "66f5c2f1a3b6e27a1a200000"
|
||||
}
|
||||
```
|
||||
|
||||
Error responses use HTTP status codes with:
|
||||
|
||||
```json
|
||||
{ "timestamp": "...", "type": "photoUploadAck", "success": false, "message": "..." }
|
||||
```
|
||||
|
||||
### Server-side side-effect (notification)
|
||||
|
||||
After a successful upload, a small event is broadcast to the specific task topic:
|
||||
|
||||
- Destination: `/topic/tasks/{taskId}`
|
||||
- Payload:
|
||||
|
||||
```json
|
||||
{ "event": "photoUploaded", "taskId": "...", "jobId": "...", "photosCount": 2, "timestamp": "..." }
|
||||
```
|
||||
|
||||
Use this to update UI (e.g., show that photos have arrived) without transferring large images via STOMP.
|
||||
|
||||
### Limits
|
||||
|
||||
- Multipart limits (configurable in `application.properties`):
|
||||
- `spring.servlet.multipart.max-file-size=32MB`
|
||||
- `spring.servlet.multipart.max-request-size=64MB`
|
||||
- Tomcat limits adjusted accordingly.
|
||||
|
||||
If you need higher limits, we can raise these values.
|
||||
|
||||
## 3) Marking Task as Completed (STOMP)
|
||||
|
||||
Continue to mark a task as completed via STOMP without embedding images:
|
||||
|
||||
- Send to: `/app/task/photo/completed`
|
||||
- Payload (no photos inside):
|
||||
|
||||
```json
|
||||
{ "taskId": "66f5c2f1a3b6e27a1a234567", "completedBy": "driver01", "note": "Anlieferung dokumentiert" }
|
||||
```
|
||||
|
||||
- Broadcasts an update to `/topic/task-updates` and `/topic/tasks/{taskId}`.
|
||||
|
||||
## 4) Retrieval of Photos (optional)
|
||||
|
||||
Currently, the backend stores uploaded photos as base64 in the `photos` collection referencing the `taskId` and `jobId`. If you need a download/list endpoint, let us know—we can expose `/api/tasks/{taskId}/photos` (GET) to return metadata and/or images.
