The "Springintegration" in the demo implements the asynchronous pattern in a listener way.

In the demo, the "topic" C-end obtains the message through the receive () method, realizes the synchronization mode.

One, the following according to the examples of these two models to do the configuration instructions:

(1) topic (Sync):

Step1. Create an initial context execution directory

InitialContext = GetContext (0)

Step2. Topic to execute a query

Topic Topic = (Topic) initialcontext.lookup ("/topic/mesdemotopic");

"/topic/mesdemotopic": to be as jndi as the server configuration.

Step3. Execute a Query connection factory

ConnectionFactory CF = (connectionfactory) initialcontext.lookup ("/connectionfactory");

Step4. Create a connection and session

Connection = Cf.createconnection ();

Session session = Connection.createsession (false, Session.auto_acknowledge);

The first parameter is whether the transaction is used, and the second parameter is how the consumer confirms to the sender that the message has been received.

There are three ways to confirm messages:

Auto_acknowledge (automatic notification)

Client_acknowledge (client's own decision to notify time)

Dups_ok_acknowledge (Delay//batch notification)

Step5. Create a sender of a message producer

MessageProducer producer = session.createproducer (topic);

Step 6. Create a consumer

Messageconsumer messageConsumer1 = session.createconsumer (topic);

STEP7. Create a message

TextMessage message = Session.createtextmessage (' This is a-text message ');

The message also includes:

(1) Byte array type: Bytesmessage

(2) Map type: Mapmessage

(3) Multiple raw data types: streammessage

(4) Object type: ObjectMessage

Step8. Send the message

Producer.send (message);

Step9. Receive the message

TextMessage messagereceived = (textmessage) messageconsumer1.receive ();

Step10. Close related connections and services

if (connection!= null)

{

Connection.close ();

}

if (InitialContext!= null)

{

Initialcontext.close ();

}

(2) springintegration (asynchronous) mode:

First of all, this example is integrated with spring.

Step1. To create a bean factory from a configuration file

Classpathxmlapplicationcontext context = new Classpathxmlapplicationcontext (new string[] {"Spring-jms-beans.xml"}); (Please see demo for specific configuration file)

Step2. Get message Sender Messagesender

Messagesender sender = (messagesender) context.getbean ("Messagesender");

Step3. Send a message

Sender.send ("Hello World");

This method creates the connection as well as session and producer, as is the case with topic.

STEP4.C received the message at the end.

When the P-side sends a message to broker, the MessageListener is taken to the queue or topic message when the listening queue or topic channel in the C-terminal changes.
