Spring Cloud Gateway с Eureka Discovery не маршрутизирует запросы к микросервисам ⇐ JAVA

[Гость]

I'm working on a project with multiple microservices registered with a Eureka Discovery Server. I've set up a Spring Cloud Gateway as an Eureka client and configured the routes accordingly. However, my requests through the Gateway result in 404 errors, while direct requests to the microservices succeed.

API Gateway application.properties:

Both my microservices (order-service and product-service) have server.port=0 for random port selection and are registered with Eureka:

order-service and product-service application.properties:

eureka.client.service-url.defaultZone=http://localhost:8761/eureka/ spring.application.name=order-service  # for order-service # spring.application.name=product-service  # for product-service 

OrderController:

@RestController @RequestMapping("/api/order") @RequiredArgsConstructor public class OrderController {     private final OrderService orderService;     @PostMapping     @ResponseStatus(HttpStatus.CREATED)     public String placeOrder(@RequestBody OrderRequest orderRequest) {         orderService.placeOrder(orderRequest);         return "Order placed successfully";     }     // ... other methods ... } 

ProductController:

@RestController @RequestMapping("/api/product") @RequiredArgsConstructor public class ProductController {     private final ProductService productService;     // ...  methods ... } 

Issue:

When making a POST request to http://localhost:8080/api/order via Postman, I receive the following error:

{     "timestamp": "2024-03-08T20:08:59.340+00:00",     "status": 404,     "error": "Not Found",     "path": "/api/order" } 

However, directly calling the order-service using its dynamically assigned port, such as

http://localhost:54062/api/order

, works correctly and I receive a

Order placed successfully

response.

What am I missing in my Gateway setup that's preventing it from routing requests to the microservices? Any insights or troubleshooting tips would be greatly appreciated.
