Hi. I'm using: - spring boot 2.1.4.Release in the three app: - One Eureka server app - Two Eureka client (client-1 and client-2) app.
Configurations:
# Eureka server:
server.port = 8761
#we have only one eureka server:
eureka.client.fetch-registry= false
eureka.client.register-with-eureka= false
spring.security.user.name= user1
spring.security.user.password= pass1
# Eureka client-1:
server.port = 8091
spring.application.name= service-1
eureka.instance.ip-address=10.10.1.51
eureka.instance.prefer-ip-address=true
eureka.client.service-url.defaultZone= http://user1:pass1@10.10.1.51:8761/eureka
eureka.instance.instance-id=10.10.1.51:service-1:8091
# Eureka client-2:
server.port = 8083
spring.application.name= service-2
eureka.instance.ip-address=10.10.1.51
eureka.instance.prefer-ip-address=true
eureka.client.service-url.defaultZone= http://user1:pass1@10.10.1.51:8761/eureka
eureka.instance.instance-id=10.10.1.51:service-2:8083
Both Eureka clients are registered in the Eureka-server successfully (both in development and production environments).
I want to call a simple GET endpoint in the client-2 from the client-1 by a loadbalanced RestTemplate.
Everything works correctly in the development environment.
But when the 3 jar files are deployed to the my VPS, I'm getting 404 null as the below when call restTemplate.getForEntity.
In the Eureka client-1:
@SpringBootApplication
@EnableEurekaClient
public class Application1 {
public static void main(String[] args) {
SpringApplication.run(Application1.class, args);
}
@Bean
@LoadBalanced
public RestTemplate restTemplate(){
return new RestTemplate();
}
}
// in one of the my @controller in client-1, I have :
@Autowired
private RestTemplate restTempate;
String serviceName = "http://service-2/my-endpoint/true";
ResponseEntity rsp = restTemplate.getForEntity(serviceName, Object.class);

what is the problem?
Comment From: spencergibb
It was a 404 not found.
Comment From: BigGitWorld
I know it is a 404 not found error, but I don't know how can I solve it.
My virtual server is behind an Apache reverse proxy. Also, my sub-domain and private network IP are sub.example.com and 10.10.1.51 respectively.
The Eureka server and both Eureka clients are inside of this virtual.
Can you tell me what is the correct configuration (eureka.instance.instance-id, eureka.instance.ip-address, etc), so that client-1 and client-2 can connect to each other by a restTemplate?
I used an interceptor for the RestTemplate in the Eureka client-1 (service-1) that result in the below logging.
# service-1
@SpringBootApplication
@EnableEurekaClient
public clas Application1 {
public static void main(String[] args) {
SpringApplication.run(Application1.class, args);
}
@Bean
@LoadBalanced
public RestTemplate restTemplate(){
RestTemplate restTemplate = new RestTemplate();
List<ClientHttpRequestInterceptor> interceptors = new ArrayList<>();
interceptors.add(new LogRequestResponseFilter());
restTemplate.setInterceptors(interceptors);
return restTemplate;
}
}
@Component
public class LogRequestResponseFilter implements ClientHttpRequestInterceptor {
private static final Logger logger = LoggerFactory.getLogger(LogRequestResponseFilter.class);
@Override
public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution)
throws IOException {
traceRequest(request, body);
ClientHttpResponse clientHttpResponse = execution.execute(request, body);
traceResponse(clientHttpResponse);
return clientHttpResponse;
}
private void traceRequest(HttpRequest request, byte[] body) throws IOException {
logger.info("==============traceRequest");
logger.info("request URI : " + request.getURI());
logger.info("request method : " + request.getMethod());
logger.info("request body : " + getRequestBody(body));
}
private String getRequestBody(byte[] body) throws UnsupportedEncodingException {
if (body != null && body.length > 0) {
return (new String(body, "UTF-8"));
} else {
return null;
}
}
private void traceResponse(ClientHttpResponse response) throws IOException {
logger.info("==============traceResponse");
logger.info("response status code: " + response.getStatusCode());
logger.info("response status text: " + response.getStatusText());
}
}
Why the request URI is not converted to "http://10.10.1.51:8083/myEndpoint" ?

Instance id doesn't have any thing to do with it except it is unique. The 404 comes from the other service by that point eureka is out of the picture. Have you looked at access logs to see what is giving a 404?

Please not that my virtual (IP 10.10.1.51) is behind an Apache reverse proxy.
If I call the service-2 endpoint directly from service-1 (for example https://sub.example.com/path/MyEndpoint), everything works fine. Because my proxy maps sub.example.com/path to my virtual. Therefore, there is not any error in my endpoint. I think this 404 error is due to Apache reverse proxy existence. Also please note that I'm using the same configuration in another VPS (without reverse proxy) and everything works fine. I don't know how do I have to configure my eureka clients in this scenario.

Look, you have to tell eureka to register with a routable host or ip address (you've configured to prefer ip address), other than that I don't know.

Thank you for you response. It was due to wrong configs of my Apache and Finally I solved it.
