First, brief introduction

ActiveMQ is an excellent JMS implementation framework, which has the advantages of simple, convenient and good performance in asynchronous message communication.

Second, installation

Download address: http://mirror.bit.edu.cn/apache/activemq/

Just decompress it.

Three, start

Windows start

Linux start

Fourth, java application

Dependent package: activemq-all-5.12.0.jar

Send a message:

/ / construct the ConnectionFactory instance object, here using the implementation of ActiveMq jarConnectionFactory connectionFactory = new ActiveMQConnectionFactory (ActiveMQConnection.DEFAULT_USER,ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616"); / / construct the connection object Connection connection = connectionFactory.createConnection () from the factory; / / start connection.start (); / / get the operation connection Session session = connection.createSession (Boolean.TRUE,Session.AUTO_ACKNOWLEDGE); Destination destination = session.createQueue ("FirstQueue") / / get the message generator [sender] MessageProducer producer = session.createProducer (destination); / / set non-persistence. Learn here and actually decide producer.setDeliveryMode (DeliveryMode.NON_PERSISTENT) according to the project.

To this producer object generation, the next step is to send data

/ / create message TextMessage message = session.createTextMessage ("message sent by ActiveMq"); / / send producer.send (message)

Consumers accept data

Create a connection as above

`/ / message consumer object

MessageConsumer consumer = session.createConsumer (destination)

/ / receive messages

TextMessage message = (TextMessage) consumer.receive (100000)

`

Fifth, message management

Built-in management: http://127.0.0.1:8161/admin/

Username password: default username password admin,admin

Set up

The main menus on the management page are: 1 ActiveMq home: current ActiveMq information, name, id, version, etc. 2 focus queues: queues running in the current message, as well as the number of producers, consumers, and queuing messages in the queue, etc.
