ActiveMQ http 连接被拒绝

Question

我尝试通过 http 将我的 Java 客户端应用程序连接到 ActiveMQ，但不断收到错误：

Failed to perform GET on: http://localhost:8080 as response was: Connection refused: connect

此连接有效，为什么我连接：tcp://localhost:61616

activemq.xml

<broker>
  ...
  <transportConnectors>
    <transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
    <transportConnector name="http" uri="http://0.0.0.0:8080"/>
  </transportConnectors>
  ...
</broker>

我的 Java 客户端程序中的 jndi.properties：

java.naming.factory.initial = org.apache.activemq.jndi.ActiveMQInitialContextFactory
#java.naming.provider.url = tcp://localhost:61616
java.naming.provider.url = http://localhost:8080
connectionFactoryNames = connectionFactory, queueConnectionFactory, topicConnectionFactry
queue.testQueue = testQueue

Java 客户端

package be.jmshub.jmsremotejndiproducer;

import javax.jms.JMSException;
import javax.jms.Connection;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.Message;
import javax.jms.Queue;
import javax.jms.QueueConnectionFactory;
import javax.naming.Context;
import javax.naming.InitialContext;

public class Producer {

    public static void main(String[] args) throws JMSException {

        System.out.println("JMS REMOTE PRODUCER: start");

        try {
            // create a new intial context, which loads from jndi.properties file
            Context ctx = new InitialContext();
            QueueConnectionFactory factory = (QueueConnectionFactory) ctx.lookup("connectionFactory");
            Connection connection = factory.createConnection();
            Queue queue = (javax.jms.Queue) ctx.lookup("testQueue");
            Session session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);

            MessageProducer producer = session.createProducer(queue);

            System.out.println("JMS REMOTE PRODUCER: connected");

            int count = 0;

            for (int i = 0; i < 5; i++) {
                String messageText = "This is message " + (i + 1);
                Message message = session.createTextMessage(messageText);
                System.out.println("JMS REMOTE PRODUCER: sending - " + messageText);
                producer.send(message);
                count += 1;
            }
            System.out.println("JMS REMOTE PRODUCER: total messages sent: " + count);

            // Clean up
            session.close();
            connection.close();
        } catch (Exception ex) {
            System.out.println("JMS REMOTE PRODUCER: EXCEPTION:" + ex.toString());
        }
        System.out.println("JMS REMOTE PRODUCER: finished");
    }
}

这适用于 tcp://localhost:61616，但不适用于 http://localhost:8080

任何人都可以帮助我启动并运行这个东西吗？

在下面找到一个启动代理的精简示例。您的

Producer

运行没有任何问题。

activemq.xml

Broker.java

package be.jmshub.jmsremotejndiproducer;

public class Broker {

    public static void main(String[] args) throws Exception {
        BrokerService broker = BrokerFactory.createBroker("xbean:foo.xml");
        broker.setPersistent(false);
        broker.start();
        broker.waitUntilStarted();
