com.Sun.jersey.api.client.ClientHandlerException：Java.net.ConnectException：接続が拒否されました：Spring Bootで接続します

私はhttp://www.javainuse.com/spring/spring-cloud-netflix-zuul-tutorialからコードを開発していますが、まだカスタマイズされていません。下記のエラーが引き続き発生します。そこで、このエラーを回避するために、application.propertiesファイル。

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

上記のプロパティを追加した瞬間、エラーは発生しません。

参考のために以下のエラー

問題は、Eurekaサーバーの正しいポートを指定していない可能性があります。ポートを指定しない場合、default port 808を使用しようとしますが、これはエラーにつながります。 application.propertiesファイルで以下に説明する構成を使用します。 8761はeurekaサーバーのデフォルトポートです

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

また、以下のようにメインクラスに注釈を付けてください。

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);
    }

}

例外接続を拒否しました。バックグラウンドですでに実行されているサーバーのポート番号を意味します。バックグラウンドで実行されているサーバーのポート番号を確認します。

このプロセスに従ってください：

バックグラウンドで同じポート番号を実行している可能性があります。Windowsの以下のコマンドを参照して強制終了します。コマンドプロンプト->以下のコマンドを実行に移動し、

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

上記のコマンドを使用して実行中のすべてのサービスを強制終了し、ポート番号を設定し、application.propertiesファイルに以下のコードを記述します。

server.port = 8761

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

上記の行を編集するだけです。正常に動作しています。

EurekaServerは実行されていますか？

同じ問題がありました。問題は、Eureka Serverを実行していないことです。 Eureka Serverを実行した後、正常に動作し始めました。

このため、私はsetting.xmlファイルを使用してそれを解決しました。このファイルは、リポジトリフォルダーのすぐ下の.m2フォルダーに配置する必要があります。 m2 reposotoryのsetting.xmlファイル

1）単純なメモ帳でこのファイルを作成する必要があります。過去のコードは以下のとおりです。

<?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">
 <pluginGroups/>
 <proxies>
  <!-- Proxy for HTTP -->
  <proxy>
   <id>optional</id>
   <active>true</active>
   <protocol>http</protocol>
   <username>proxyuser</username>
   <password>proxypass</password>
   <Host>172.25.33.10</Host>
   <port>8080</port>
   <nonProxyHosts>local.net</nonProxyHosts>
  </proxy>

  <!-- Proxy for HTTPS -->
  <proxy>
   <id>optional</id>
   <active>true</active>
   <protocol>https</protocol>
   <username>proxyuser</username>
   <password>proxypass</password>
   <Host>172.25.33.10</Host>
   <port>8080</port>
   <nonProxyHosts>local.net</nonProxyHosts>
  </proxy>
 </proxies>

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

このファイルをsetting.xmlとして保存するより

リポジトリの下の.m2フォルダーに配置します

2）IDE（私はEclipseを使用しています）、windows-> preference-user setting-> browsing file path to setting.xml（C：\ Users\himanshun.m2\settings .xml）->更新設定をクリック->適用して閉じる
