feign启动报错

Question

配置都是按照老师给的版本来的，micro-weather-eureka-client-feign启动报错，卡到这了，实在找不到原因，老师能给看看吗？

已解决

最开始用的老师视频给的配置的版本，报错Caused by: java.lang.ClassNotFoundException org.springframework.cloud.client.loadbalancer.LoadBalancedRetryFactory

最终解决方法：
1.

改springBootVersion = '2.0.1.RELEASE'
springCloudVersion = 'Finchley.M9'
报org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'eurekaAutoServiceRegistration': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

2.

最后对比老师github的配置代码，又追加了 compile('org.springframework.boot:spring-boot-starter-web')这个就可以了

看下你的 applicaiton 的配置类是怎么写的？

• 提问者 3333CR7_0 #1

  这个类吗
  import org.springframework.boot.SpringApplication;
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
  import org.springframework.cloud.netflix.feign.EnableFeignClients;
  
  @SpringBootApplication
  @EnableDiscoveryClient
  @EnableFeignClients
  public class Application {
  
  	public static void main(String[] args) {
  		SpringApplication.run(Application.class, args);
  	}
  }

  说错，是applicaiton 配置文件，怎么写的？

• 提问者 3333CR7_0 回复 老卫 #3

  spring.application.name: micro-weather-eureka-client-feign
  
  eureka.client.serviceUrl.defaultZone: http://localhost:8761/eureka/
  feign.client.config.feignName.connectTimeout: 5000
  feign.client.config.feignName.readTimeout: 5000
