Spring JMS - 无法使用嵌入式代理连接到代理 URL

Question

Here's my JmsMessageSender

@Service
public class JmsMessageSender {

    @Autowired
    private JmsTemplate jmsTemplate;


    /**
     * send text to default destination
     * @param text
     */
    public void send(final String text) {

        this.jmsTemplate.send(new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
                Message message = session.createTextMessage(text);
                return message;
            }
        });
    }

    /**
     * Simplify the send by using convertAndSend
     * @param text
     */
    public void sendText(final String text) {
        this.jmsTemplate.convertAndSend(text);
    }

    /**
     * Send text message to a specified destination
     * @param text
     */
    public void send(final Destination dest,final String text) {

        this.jmsTemplate.send(dest,new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
                Message message = session.createTextMessage(text);
                return message;
            }
        });
    }
}

Here's my DemoClass

public class DemoMain {

    public static void main(String[] args) {
        // init spring context
        ApplicationContext ctx = new ClassPathXmlApplicationContext("context.xml");

        // get bean from context
        JmsMessageSender jmsMessageSender = (JmsMessageSender)ctx.getBean("jmsMessageSender");

        // send to default destination
        jmsMessageSender.send("hello JMS");

        // send to a code specified destination
        Queue queue = new ActiveMQQueue("AnotherDest");
        jmsMessageSender.send(queue, "hello Another Message");

        // close spring application context
        ((ClassPathXmlApplicationContext)ctx).close();
    }

}

My context.xml

and my activemq.xml configuration.

However when I run my main class this error shows. Did I miss anything in the config?

Caused by: javax.jms.JMSException: Could not connect to broker URL: tcp://192.168.203.143:61616. Reason: java.net.ConnectException: Connection timed out: connect

Answer 1

Have you started the AMQ-broker on tcp://192.168.203.143:61616 ? If not then starting it should solve the problem.

Answer 2

Had simillar Errors. Heres solution.

try to connect to borker at your ip address Could not connect to broker URL: tcp://192.168.203.143:61616. above mentioned ip address is relevent to Example's System.

try to run same code for your ip address.(Know your ipAddress in network settings or command "ipconfig")
Could not connect to broker URL: tcp://192.168.1.184:61616.
