Send Message by Spring JMS

The JmsTemplate contains many convenience methods to send a message. There are send methods that specify the destination using a javax.jms.Destination object and those that specify the destination using a string for use in a JNDI lookup. The send method that takes no destination argument uses the default destination. Here is an example that sends a message to a queue using the 1.0.2 implementation.

import javax.jms.ConnectionFactory;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Queue;
import javax.jms.Session;

import org.springframework.jms.core.MessageCreator;
import org.springframework.jms.core.JmsTemplate;

public class JmsQueueSender {

    private JmsTemplate jmsTemplate;
    private Queue queue;

    public void setConnectionFactory(ConnectionFactory cf) {
        this.jmsTemplate = new JmsTemplate(cf, false);
    }

    public void setQueue(Queue queue) {
        this.queue = queue;
    }

    public void simpleSend() {
        this.jmsTemplate.send(this.queue, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
              return session.createTextMessage("hello queue world");
            }
        });
    }
}

 This example uses the MessageCreator callback to create a text message from the supplied Session object and the JmsTemplate is constructed by passing a reference to a ConnectionFactory and a boolean specifying the messaging domain. A zero argument constructor and connectionFactory / queue bean properties are provided and can be used for constructing the instance (using a BeanFactory or plain Java code). Alternatively, consider deriving from Spring's JmsGatewaySupport convenience base class, which provides pre-built bean properties for JMS configuration.

The method send(String destinationName, MessageCreator creator) lets you send to a message using the string name of the destination. If these names are registered in JNDI, you should set the destinationResolver property of the template to an instance of JndiDestinationResolver.

If you created the JmsTemplate and specified a default destination, the send(MessageCreator c) sends a message to that destination.
