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

這篇文章主要介紹了netflix.discovery.shared.transport.TransportException:Cannot execute request on any known server報(bào)錯(cuò)問題及解決方法,感興趣的朋友一起看看吧

報(bào)錯(cuò)

 當(dāng)我們啟動(dòng)項(xiàng)目報(bào)錯(cuò)：

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

這個(gè)報(bào)錯(cuò)是因?yàn)槭褂昧薊ureka。Eureka會(huì)啟用服務(wù)發(fā)現(xiàn)服務(wù)治理，所以你會(huì)看到Eureka，discovery，server等關(guān)鍵詞。

Eureka之所以會(huì)報(bào)錯(cuò)，是因?yàn)槟闩渲梦募]有配置Eureka的相關(guān)配置。所以它會(huì)默認(rèn)使用你本機(jī)的DNS和本機(jī)的主機(jī)名。例如我這里的是123091-NB02.yun.alibaba.com:8030（見具體報(bào)錯(cuò)），123091是我的工號(hào)，yun.alibaba.com是我公司內(nèi)部的域名。

windows系統(tǒng)下，cmd使用命令 ipconfig /all 查看網(wǎng)絡(luò)配置信息可以看到：

D:\>ipconfig /all
Windows IP 配置
   主機(jī)名  . . . . . . . . . . . . . : 123091-NB02
   主 DNS 后綴 . . . . . . . . . . . : yun.alibaba.com
   節(jié)點(diǎn)類型  . . . . . . . . . . . . : 混合
   IP 路由已啟用 . . . . . . . . . . : 否
   WINS 代理已啟用 . . . . . . . . . : 否

解決方法

這種問題通常會(huì)出現(xiàn)在我們接手了別人的項(xiàng)目里，如果該項(xiàng)目只是一個(gè)簡單的springboot，不需要微服務(wù)，不需要cloud。

方法一： 去掉maven依賴

但報(bào)了這個(gè)錯(cuò)，通常是因?yàn)閜om文件里有eureka的依賴。

pom.xml里，需要注釋掉（注釋完記得reload一下maven，右上角會(huì)出現(xiàn)刷新圖標(biāo)）

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

 啟動(dòng)類里，需要注釋掉

//@EnableEurekaClient
@SpringBootApplication
public class Application {}

當(dāng)然，有可能你項(xiàng)目里用到了eureka這個(gè)包里的類。例如我項(xiàng)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依賴。這里不需要引入aspectjweaver（其包含aspectjrt），springboot的aop包有aspectjweaver

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

還有另外兩個(gè)偷懶辦法：

方法二：直接在application配置文件里禁用eureka

# 是否將自己注冊到 Eureka-Server 中，默認(rèn)true
eureka.client.register-with-eureka=false
# 是否需要拉取服務(wù)信息，默認(rèn)true
eureka.client.fetch-registry=false

方法三：檢查eureka配置的地址是否正確

# 則在Eureka服務(wù)發(fā)現(xiàn)應(yīng)該配置為：
# http://127.0.0.1:8080/eureka/
server.port: 8080
eureka.client.serviceUrl.defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

具體報(bào)錯(cuò)如下：
