연결이 거부되었습니다. RabbitMQ

Question

저는 RabbitMQ를 처음 사용하고 간단한 예를 시도하고 있습니다. 아래는 내 자바 소스 :

import com.rabbitmq.client.ConnectionFactory; 
import com.rabbitmq.client.Connection; 
import com.rabbitmq.client.Channel; 

public class Send { 

    private final static String QUEUE_NAME = "hello"; 

    public static void main(String[] argv) throws Exception { 

    ConnectionFactory factory = new ConnectionFactory(); 
    factory.setHost("localhost"); 
    Connection connection = factory.newConnection(); 
    Channel channel = connection.createChannel(); 

    channel.queueDeclare(QUEUE_NAME, false, false, false, null); 
    String message = "Hello World!"; 
    channel.basicPublish("", QUEUE_NAME, null, message.getBytes()); 
    System.out.println(" [x] Sent '" + message + "'"); 

    channel.close(); 
    connection.close(); 
    } 
} 

그리고 오류가 아래에 무엇입니까 : 스레드에서

예외 "주요"java.net.ConnectException : 연결이 거부 됨 :

어떤 제안을 연결하십시오 ?

Answer 1

RabbitMQ 서버를 설치 했습니까?

또한 rabbitmq-client.jar 및 클래스 경로에 대한 종속성이 있습니까?

터미널에서이 작업을 실행 해보십시오 :

java -cp .:commons-io-1.2.jar:commons-cli-1.1.jar:rabbitmq-client.jar Send
