java - 关机信号异常 : connection error RabbitMQ on STS4

Question

我试图在本地端口 15672 上连接到 RabbitMQ，但出现连接错误。我不确定是什么原因造成的，因为我正在尝试学习 RabbitMQ...这是教程 1，我什至无法运行。 ( https://www.rabbitmq.com/tutorials/tutorial-one-java.html )

下面是代码和错误。我对教程所做的唯一更改是指定端口和用户名/密码。有什么想法吗？

package send.java;

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");
        factory.setPort(15672);
        factory.setUsername("guest");
        factory.setPassword("guest");
        try (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 + "'");
        }
    }

}

错误

Answer 1

端口 15672 是管理(管理插件)UI 的(默认)HTTP 端口。

默认的 AMQP 端口是 5672。
