Spring Cloud and Eureka: java.lang.IllegalStateException: No instances available for ACCOUNTS-SERVICE

Solution 1

I believe @LoadBalanced in WebAccountService.restTemplate is not needed. I also think the service name being used in:

public Account getByEmail(String email) {
    logger.info("serviceurl = " + serviceUrl);
    return restTemplate.getForObject(serviceUrl
                + "/accounts/{email}", Account.class, email);
}

might be incorrect. Could you paste you bootstrap and application properties files? It might need to be a key mapped to the service name located in one of these files, something like:

the-demo-registration-api-1:
   ribbon:
     # Eureka vipAddress of the target service
     DeploymentContextBasedVipAddresses: demo-registration-api-1

then using http://the-demo-registration-api-1 instead of the service name.

I recently blogged about Microservices Registration and Discovery using Spring Cloud, Eureka, Ribbon and Feign at http://tech.asimio.net/2016/11/14/Microservices-Registration-and-Discovery-using-Spring-Cloud-Eureka-Ribbon-and-Feign.html#load-balancing-requests-using-resttemplate-and-loadbalanced where different options to send requests to registered services are discussed such as load-balancing requests using Spring Cloud Feign, load-balancing requests using RestTemplate AND @LoadBalanced and load-balancing requests using RestTemplate AND LoadBalancerClient.

Hopefully it can answer your question.

Updated:

WebServer service would need Ribbon configuration so that it can find the Account service in the registry:

eureka:
  client:
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://localhost:8000/eureka/
  instance:
    ...
    metadataMap:
      instanceId: ${spring.application.name}:${server.port}

the-accounts-service:
  ribbon:
    # Eureka vipAddress of the target service
    DeploymentContextBasedVipAddresses: accounts-service

    #listOfServers: localhost:${SERVER.PORT}
    NIWSServerListClassName: com.netflix.niws.loadbalancer.DiscoveryEnabledNIWSServerList

    # Interval to refresh the server list from the source (ms)
    ServerListRefreshInterval: 30000

Solution 2

I had the same problem and i fixed it by removing @LoadBalanced from the bean

Solution 3

Try to add in application.properties of WebServer the value spring.cloud.loadbalancer.ribbon.enabled = false

    I've been trying to create microservices with Spring Cloud and Eureka.

    For now I have a server that picks up 2 microservices: ACCOUNTS-SERVICE and WEB-SERVICE

    [nio-1111-exec-2] c.n.e.registry.AbstractInstanceRegistry  : Registered instance ACCOUNTS-SERVICE/192.168.0.13:accounts-service:2222 with status UP (replication=false)
[nio-1111-exec-4] c.n.e.registry.AbstractInstanceRegistry  : Registered instance WEB-SERVICE/192.168.0.13:web-service:3333 with status UP (replication=false)

    This is my web service:

    package eu.epitech.jug.services.web;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.client.RestTemplate;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

/**
 * Created by sadzeih on 12/9/16.
 */
@SpringBootApplication
@EnableDiscoveryClient
@ComponentScan(useDefaultFilters=false)
public class WebServer {
    public static void main(String[] args) {
        // Will configure using web-server.yml
        System.setProperty("spring.config.name", "web-server");
        SpringApplication.run(WebServer.class, args);
    }

    @Bean
    @LoadBalanced
    RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @Bean
    public WebAccountService accountService()
    {
        return new WebAccountService("http://ACCOUNTS-SERVICE");
    }

    @Bean
    public WebAccountController accountController() {
        return new WebAccountController(accountService());
    }
}

    In WebAccountService there is this:

    package eu.epitech.jug.services.web;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;


/**
 * Created by sadzeih on 12/9/16.
 */
@Service
public class WebAccountService {
    @Autowired
    @LoadBalanced
    protected RestTemplate restTemplate;

    protected String serviceUrl;

    protected Logger logger = Logger.getLogger(WebAccountService.class.getName());

    public WebAccountService(String serviceUrl) {
        this.serviceUrl = serviceUrl.startsWith("http") ?
                serviceUrl : "http://" + serviceUrl;
    }

    public Account getByEmail(String email) {
        logger.info("serviceurl = " + serviceUrl);
        return restTemplate.getForObject(serviceUrl
                + "/accounts/{email}", Account.class, email);
    }

}

    And in the controller it's just a route. But this happens:

    [nio-3333-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: No instances available for ACCOUNTS-SERVICE] with root cause

    You can find the code here: https://github.com/Sadzeih/microservices-test

    I've been trying to find the problem, but I definitely can't.

    Thanks for the help!

    Also, I tried doing the key mapped to the service as you showed, and it produced the same error with the-account-service instead

    The ability of RestTemplate to work with service names is provided by Ribbon. I couldn't find any Ribbon configuration in your yml and properties files. Something like: ` the-demo-registration-api-1: ribbon: # Eureka vipAddress of the target service DeploymentContextBasedVipAddresses: demo-registration-api-1 #listOfServers: localhost:${SERVER.PORT} NIWSServerListClassName: com.netflix.niws.loadbalancer.DiscoveryEnabledNIWSServerList # Interval to refresh the server list from the source (ms) ServerListRefreshInterval: 30000 ` in WebServer

    @Sadzeih I have edited my initial answer to include Ribbon configuration needed in WebServer service

    I updated my code to reflect your answer but still getting the same error. java.lang.IllegalStateException: No instances available for the-account-service. You can see the changes in the repository

    When you open localhost:1111/eureka in a browser, do you see ACCOUNTS-SERVICE and WEB-SERVICE there?

    @Sadzeih The only thing I can think off the top of my head is that WebServer service is not fetching the registry. Could you add eureka.client.fetchRegistry: true to its yml file while keeping all the changes I have mentioned before?
