com.sun.vmdk.api.client.ClientHandlerException: java.net .예외 연결:연결 거부됨: Spring Boot에서 연결

저는 아직 커스터마이징이 없는 http://www.javainuse.com/spring/spring-cloud-netflix-zuul-tutorial, 의 코드를 개발하고 있습니다.아래에 언급된 오류가 계속 발생합니다.그래서 이 오류를 피하기 위해 다음을 추가했습니다.application.properties파일.

eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.client.server.waitTimeInMsWhenSyncEmpty=0

위의 속성을 추가한 순간 오류가 발생하지 않습니다.

아래의 오류는 참조용입니다.

그 속성을 추가하는 순간 어떤 인스턴스도 얻을 수 없습니다.

그래서 제 질문은, 어떻게 하면 이 게시물에 언급된 첫 번째 오류를 피할 수 있을까요? 안내 부탁드립니다.

문제는 Eureka 서버에 올바른 포트를 지정하지 않은 것일 수 있습니다.포트를 지정하지 않으면 기본 포트 8080을 사용하려고 하므로 오류가 발생합니다.application.properties 파일에 아래에 설명된 구성을 사용합니다.8761은 eureka 서버의 기본 포트입니다.

server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

또한 아래와 같이 메인 클래스에 주석을 달아야 합니다.

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }

}

예외 연결이 거부되었습니다.백그라운드에서 이미 실행 중인 서버 포트 번호를 의미합니다.백그라운드에서 실행 중인 서버 포트 번호를 확인합니다.

다음 프로세스를 수행합니다.

백그라운드에서 동일한 포트 번호를 실행하고 있을 수 있습니다. 창에서 아래 명령을 참조하고 제거하십시오.명령 프롬프트로 이동 ->아래 명령 실행,

Find open running ports:

C:\WINDOWS\system32>netstat -ano | findstr :Port number

Example: netstat -ano | findstr :8761

kill ports based on PID(process ID)

C:\WINDOWS\system32>taskkill /PID PIDNumber /F 

Example: taskkill /PID 3740 /F

위의 명령을 사용하여 실행 중인 모든 서비스를 종료하고 application.properties 파일에 포트 번호를 설정하고 코드 아래에 씁니다.

server.port=8761

#set port number
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetchRegistry=false
eureka.client.server.waitTimeInMsWhenSyncEmpty=0

위의 행만 편집하면 됩니다.잘 작동하는

EurekaServer가 실행되고 있습니까?

저도 같은 문제가 있었습니다. 문제는 제가 유레카 서버를 실행하지 않았다는 것입니다.유레카 서버를 실행한 후 잘 작동하기 시작했습니다.

application.properties 파일에 다음 구성을 추가하기만 하면 됩니다.

#Eureka's default port
server.port=8761

이를 위해 방금 setting.xml 파일을 사용하여 해결했습니다. setting.xml 파일은 저장소 폴더 바로 아래에 있는 .m2 폴더에 있어야 합니다.m2 저장소의 .xml 파일 설정

당신은 이 파일을 아래 코드를 지난 간단한 메모장으로 만들어야 합니다.

<?xml version="1.0" encoding="UTF-8"?>
<settings
 xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

   <protocol>http</protocol>
   <username>proxyuser</username>
   <password>proxypass</password>
   <host>172.25.33.10</host>
   <port>8080</port>
   <nonProxyHosts>local.net</nonProxyHosts>
  </proxy>

   <port>8080</port>
   <nonProxyHosts>local.net</nonProxyHosts>
  </proxy>
 </proxies>

 <servers/>
 <mirrors/>
 <profiles/>
</settings>

이 파일을 setting.xml로 저장하는 것보다

그리고 그것을 저장소 아래의 .m2 폴더에 넣습니다.

IDE(이클립스 사용)로 이동하기 전에 windows->preference-user setting->settings.xml(C:\Users\himanshun.m2\settings.xml)로 파일 경로를 찾아 setting.xml(C:\Users\himanshun.m2\settings.xml) ->update setting -> 적용 및 닫기

마이크로 서비스를 등록할 룩업 서버에 속성을 구성했기 때문입니다.

## eureka.client.eureka-server-port=8761 // on which port server is running

그래서 먼저 유레카 서버를 시작하면 유레카 서버가 등록됩니다.

저는 settings.xml에 정의된 프록시 서버가 문제를 일으켰습니다.

Windows C:/Users/[username]/.m2/ 디렉토리에 있는 settings.xml에서

전용 파일을 삭제하거나 주석을 달아야 합니다.<servers>,<proxies>,<mirrors>또는<profiles>연결 문제를 일으킬 수 있습니다.
