| # Order Service | ||
| This service monitors incoming order requests from the car UI (Car Dashboard), executes the order placement, and provides the relevant response. | ||
|
|
||
| ## Prerequisites | ||
| We must set up Axon Server to handle command and query operations, and configure MySQL as the persistent store destination. | ||
|
|
||
|  | ||
|
|
||
| ## Local setup | ||
|
|
||
| - Setup axon-server and MySQL docker images | ||
| ``` | ||
| local-dev > docker compose up -d | ||
| ``` | ||
| - Run the application | ||
| ``` | ||
| order-service > mvn clean springboot:run | ||
| ``` | ||
| - Endpoint for resting | ||
| - Generate a request for an order. | ||
| ```arm | ||
| curl --location 'http://localhost:9090/orders/create' \ | ||
| --header 'Content-Type: application/json' \ | ||
| --data '{ | ||
| "productId": "199", | ||
| "quantity": 1, | ||
| "userId": "1652" | ||
| }' | ||
| ``` | ||
| - Get user's order. | ||
| ``` | ||
| curl --location 'http://localhost:9090/orders/1652' | ||
| ``` | ||
