"JAVA.JMS" A simple JMS instance

Select Activemq.

To establish a simple Maven project, the Pom.xml is as follows:

<project xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi: schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" > < Modelversion>4.0.0</modelversion> <groupId>com.gof</groupId> <artifactId>jms-test< /artifactid> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name> jms-test</name> <url>http://maven.apache.org</url> <properties> <project.build.sourcee

To create a test class:

Import Javax.jms.DeliveryMode;
Import javax.jms.Destination;
Import Javax.jms.Message;
Import Javax.jms.MessageConsumer;
Import Javax.jms.MessageProducer;
Import javax.jms.Session;

Import Javax.jms.TextMessage;

            Create the session session = Connection.createsession (transacted, Session.auto_acknowledge);
            
            Destination Destination = Session.createqueue (queuename);
            Create the producer MessageProducer producer = Session.createproducer (destination);
            if (persistent) {Producer.setdeliverymode (deliverymode.persistent);

            Blocking till receive the message Recvmessage = Consumer.receive ();

To start the test:

Start Activemq and create a queue named Test_queue in the admin page (http://localhost:8161/admin):

Run the program step-by-step when calling:

Producer.send (message);

You can see ACTIVEMQ received this message:

You can also see the current active Producer for the queue:

When calling:

Consumer.receive ();

You can see that the message is consumed:

In the console, you can see the results of the output:

Send Message:hello jms!
Receive Message:hello jms!
