ShutdownSignalException: connection error RabbitMQ on STS4
问题
我正尝试在本地连接到RabbitMQ的15672端口，但遇到连接错误。我不确定是什么原因导致这个问题，因为我正在尝试学习RabbitMQ... 这是教程1，我甚至无法运行它。 (https://www.rabbitmq.com/tutorials/tutorial-one-java.html)
以下是代码和错误信息。我所做的唯一更改是指定了端口和用户名/密码。有什么建议吗？
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 + "'");
}
}
}

I am attempting to connect to RabbitMQ locally on port 15672 but am getting connection error. I am unsure what could be causing this as I am attempting to learn RabbitMQ... This is tutorial 1 I can't even get running. (https://www.rabbitmq.com/tutorials/tutorial-one-java.html)
Below is the code and error. The only changes from the tutorial I have made are specifying the port and username/password. Any ideas?
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 + "'");
}
}
}
