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-2.5.1.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-2.5.1.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-2.5.1.nar in the pulsar connectors catalog. 
    cp pulsar-io-activemq-2.5.1.nar $PULSAR_HOME/connectors/pulsar-io-activemq-2.5.1.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();
                }
            }
        }
    });
}
