Spring Cloud和Eureka：java.lang.IllegalStateException：没有可用于ACCOUNTS-SERVICE的实例

标签： spring spring-cloud netflix-eureka

我一直在尝试使用Spring Cloud和Eureka创建微服务。

现在我有一台服务器可以获得2个微服务：ACCOUNTS-SERVICE和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)

这是我的网络服务：

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());
    }
}

在WebAccountService中有这样的：

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);
    }

}

在控制器中它只是一条路线。但这种情况发生了：

您可以在此处找到代码：https://github.com/Sadzeih/microservices-test

我一直试图找到问题，但我绝对不能。

感谢您的帮助！

3 个答案:

答案 0 :(得分：3)

我遇到了同样的问题，我通过从bean中删除@LoadBalanced来解决了这个问题

答案 1 :(得分：1)

我认为@LoadBalanced中不需要WebAccountService.restTemplate。 我还认为使用的服务名称是：

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

可能不正确。你能粘贴引导程序和应用程序属性文件吗？它可能需要是映射到位于其中一个文件中的服务名称的键，如：

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

然后使用http://the-demo-registration-api-1代替服务名称。

我最近在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使用Spring Cloud，Eureka，Ribbon和Feign撰写了有关微服务注册和发现的博客，其中讨论了向注册服务发送请求的不同选项，例如load-balancing requests using Spring Cloud Feign，load-balancing requests using RestTemplate AND @LoadBalanced和load-balancing requests using RestTemplate AND LoadBalancerClient。

希望它可以回答你的问题。

更新：

WebServer服务需要Ribbon配置，以便它可以在注册表中找到帐户服务：

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

答案 2 :(得分：0)

经过多次更改后，我找到了解决问题的方法。 我只是将微服务分成不同的模块，一切都很有效。 不要试图将多个微服务集成到一个模块中，你只会遇到麻烦。
