Spring Cloud и Eureka: java.lang.IllegalStateException: Нет экземпляров для ACCOUNTS-SERVICE

Question

Я пытаюсь создать микросервисы с Spring Cloud и Eureka.

На данный момент у меня есть сервер, который улавливает 2 microservices: СЧЕТА-СЕРВИС и WEB-СЕРВИС

[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) 

Это мой веб-сервис:

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()); 
    } 
} 

В WebAccountService есть это:

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); 
    } 

} 

И в контроллере это всего лишь маршрут. Но это происходит:

[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

Вы можете найти код здесь: https://github.com/Sadzeih/microservices-test

Я пытался найти проблему, но я определенно не могу.

Спасибо за помощь!

Answer 1

Я считаю, что @LoadBalanced в WebAccountService.restTemplate не требуется. Я также думаю, что имя службы используется в:

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

может быть неправильным. Не могли бы вы вставить файлы загрузочных файлов и приложений? Это может понадобиться, чтобы быть ключом отображается имя службы, расположенной в одном из этих файлов, что-то вроде:

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

http://the-demo-registration-api-1 затем используя вместо имени службы.

Недавно я писал о Microservices регистрации и обнаружение с использованием Spring Cloud, Eureka, лента и Feign в 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, где различные варианты для отправки запросов, зарегистрированных услуги обсуждаются такие как load-balancing requests using Spring Cloud Feign, load-balancing requests using RestTemplate AND @LoadBalanced и load-balancing requests using RestTemplate AND LoadBalancerClient.

Надеюсь, он может ответить на ваш вопрос.

Обновлен:

WebServer служба будет нуждаться в Ribbon конфигурации так, что он может найти службу учетной записи в реестре:

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 

Answer 2

Таким образом, после многих изменений, я нашел решение моей проблемы. Я просто разделил микросервисы на разные модули, и все в значительной степени сработало. Не пытайтесь сделать несколько микросервисов в одном модуле, вы попадете в беду.
