netflix.discovery.shared.transport.TransportException:Cannot execute request on any known server

作者：globalcoding

这篇文章主要介绍了netflix.discovery.shared.transport.TransportException:Cannot execute request on any known server报错问题及解决方法,感兴趣的朋友一起看看吧

报错

 当我们启动项目报错：

2023-09-13 16:25:47.875 [] [] [main] ERROR com.netflix.discovery.shared.transport.decorator.RedirectingEurekaHttpClient -Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:8761/eureka/}
com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect
    at com.sun.jersey.client.apache4.ApacheHttpClient4Handler.handle(ApacheHttpClient4Handler.java:187)
    at com.sun.jersey.api.client.filter.GZIPContentEncodingFilter.handle(GZIPContentEncodingFilter.java:123)
    at com.netflix.discovery.EurekaIdentityHeaderFilter.handle(EurekaIdentityHeaderFilter.java:27)

com.netflix.discovery.shared.transport.TransportException: 
Cannot execute request on any known server

这个报错是因为使用了Eureka。Eureka会启用服务发现服务治理，所以你会看到Eureka，discovery，server等关键词。

Eureka之所以会报错，是因为你配置文件没有配置Eureka的相关配置。所以它会默认使用你本机的DNS和本机的主机名。例如我这里的是123091-NB02.yun.alibaba.com:8030（见具体报错），123091是我的工号，yun.alibaba.com是我公司内部的域名。

windows系统下，cmd使用命令 ipconfig /all 查看网络配置信息可以看到：

D:\>ipconfig /all
Windows IP 配置
   主机名  . . . . . . . . . . . . . : 123091-NB02
   主 DNS 后缀 . . . . . . . . . . . : yun.alibaba.com
   节点类型  . . . . . . . . . . . . : 混合
   IP 路由已启用 . . . . . . . . . . : 否
   WINS 代理已启用 . . . . . . . . . : 否

解决方法

这种问题通常会出现在我们接手了别人的项目里，如果该项目只是一个简单的springboot，不需要微服务，不需要cloud。

方法一： 去掉maven依赖

但报了这个错，通常是因为pom文件里有eureka的依赖。

pom.xml里，需要注释掉（注释完记得reload一下maven，右上角会出现刷新图标）

         <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

 启动类里，需要注释掉

//@EnableEurekaClient
@SpringBootApplication
public class Application {}

当然，有可能你项目里用到了eureka这个包里的类。例如我项目里用到了aop的aspectj。

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
@Aspect
@Pointcut(value = "execution(public * com.alibaba.yun.controller..*Controller.*(..))")

需要引入springboot的aop依赖。这里不需要引入aspectjweaver（其包含aspectjrt），springboot的aop包有aspectjweaver

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

还有另外两个偷懒办法：

方法二：直接在application配置文件里禁用eureka

# 是否将自己注册到 Eureka-Server 中，默认true
eureka.client.register-with-eureka=false
# 是否需要拉取服务信息，默认true
eureka.client.fetch-registry=false

方法三：检查eureka配置的地址是否正确

# 则在Eureka服务发现应该配置为：
# http://127.0.0.1:8080/eureka/
server.port: 8080
eureka.client.serviceUrl.defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
