I’m using springboot, zuul and eureka.

When I try to reach a springboot endpoint through a zuul service, I get 404 NOT FOUND.

I run all the services with docker containers.

Do anyone of you know what might be wrong?

The springboot service with the resouces (which I’m trying to reach through zuul) is called ContentService.

The endpoint in the ContentService I’m trying to reach

@RestController
@RequestMapping("/content")
@RequiredArgsConstructor
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class CommunityController {


    private CommuntiyService communtiyService;

    @Autowired
    private ACLverifier acLverifier;


    @Autowired
    private RabbitTemplate rabbitTemplate;

    @PostMapping("/send_message/{message}")
    public void sendMessage(
            @PathVariable("message") String message
    ) {
        System.out.println("sent message: " + message);
        rabbitTemplate.convertAndSend("commentExchange", "commentRoutingKey", message);
    }

Post request Im sending:

http://localhost:8080/cont/content/send_message/hallo

Response – 404 NOT FOUND:

{
    "timestamp": "2024-06-26T08:20:29.052+00:00",
    "path": "/cont/content/send_message/hallo",
    "status": 404,
    "error": "Not Found",
    "requestId": "2355b902"
}
