報錯

 當(dāng)我們啟動項目報錯：

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

這個報錯是因為使用了Eureka。Eureka會啟用服務(wù)發(fā)現(xiàn)服務(wù)治理，所以你會看到Eureka，discovery，server等關(guān)鍵詞。

Eureka之所以會報錯，是因為你配置文件沒有配置Eureka的相關(guān)配置。所以它會默認(rèn)使用你本機的DNS和本機的主機名。例如我這里的是123091-NB02.yun.alibaba.com:8030（見具體報錯），123091是我的工號，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
   主機名  . . . . . . . . . . . . . : 123091-NB02
   主 DNS 后綴 . . . . . . . . . . . : yun.alibaba.com
   節(jié)點類型  . . . . . . . . . . . . : 混合
   IP 路由已啟用 . . . . . . . . . . : 否
   WINS 代理已啟用 . . . . . . . . . : 否

解決方法

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

方法一： 去掉maven依賴

但報了這個錯，通常是因為pom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>

 啟動類里，需要注釋掉

//@EnableEurekaClient
@SpringBootApplication
public class Application {}

當(dāng)然，有可能你項目里用到了eureka這個包里的類。例如我項目里用到了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/
