Configure ActiveMQ sink connector

Before using the ActiveMQ sink connector, you need to create a configuration file through one of the following methods.

  • JSON

    {
        "tenant": "public",
        "namespace": "default",
        "name": "activemq-sink",
        "inputs": ["user-op-queue-topic"],
        "archive": "connectors/pulsar-io-activemq-0.0.1.nar",
        "parallelism": 1,
        "configs":
        {
            "protocol": "tcp",
            "host": "localhost",
            "port": "61616",
            "username": "admin",
            "password": "admin",
            "queueName": "user-op-queue-pulsar"
        }
    }
    
  • YAML

    tenant: "public"
    namespace: "default"
    name: "activemq-sink"
    inputs: 
      - "user-op-queue-topic"
    archive: "connectors/pulsar-io-activemq-0.0.1.nar"
    parallelism: 1
    
    configs:
        protocol: "tcp"
        host: "localhost"
        port: "61616"
        username: "admin"
        password: "admin"
        queueName: "user-op-queue-pulsar"
    

Usage

  1. Prepare ActiveMQ service.

    docker pull rmohr/activemq
    docker run -p 61616:61616 -p 8161:8161 rmohr/activemq
    
  2. Put the pulsar-io-activemq-0.0.1.nar in the pulsar connectors catalog.

    cp pulsar-io-activemq-0.0.1.nar $PULSAR_HOME/connectors/pulsar-io-activemq-0.0.1.nar
    
  3. Start Pulsar in standalone mode.

    $PULSAR_HOME/bin/pulsar standalone
    
  4. Run ActiveMQ sink locally.

    $PULSAR_HOME/bin/pulsar-admin sink localrun --sink-config-file activemq-sink-config.yaml
    
  5. Send Pulsar messages.

    $PULSAR_HOME/bin/pulsar-client produce public/default/user-op-queue-topic --messages hello -n 10
    
  6. Consume ActiveMQ messages.

    Use the test method receiveMessage of the class org.apache.pulsar.ecosystem.io.activemq.ActiveMQDemo to consume ActiveMQ messages.

    @Test
    private void receiveMessage() throws JMSException, InterruptedException {
    
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
    
        @Cleanup
        Connection connection = connectionFactory.createConnection();
        connection.start();
    
        @Cleanup
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
    
        Destination destination = session.createQueue("user-op-queue-pulsar");
    
        @Cleanup
        MessageConsumer consumer = session.createConsumer(destination);
    
        consumer.setMessageListener(new MessageListener() {
            @Override
            public void onMessage(Message message) {
                if (message instanceof ActiveMQTextMessage) {
                    try {
                        System.out.println("get message ----------------- ");
                        System.out.println("receive: " + ((ActiveMQTextMessage) message).getText());
                    } catch (JMSException e) {
                        e.printStackTrace();
                    }
                }
            }
        });
    }
