Examples with MessageListener io.openmessaging.MessageListener used on opensource projects

Example 1 with MessageListener

use of io.openmessaging.MessageListener in project rocketmq-rocketmq-all-4.1.0-incubating by lirenzuo.

the class SimplePushConsumer method main.

public static void main(String[] args) {
    final MessagingAccessPoint messagingAccessPoint = MessagingAccessPointFactory.getMessagingAccessPoint("openmessaging:rocketmq://IP1:9876,IP2:9876/namespace");
    final PushConsumer consumer = messagingAccessPoint.createPushConsumer(OMS.newKeyValue().put(NonStandardKeys.CONSUMER_GROUP, "OMS_CONSUMER"));
    messagingAccessPoint.startup();
    System.out.printf("MessagingAccessPoint startup OK%n");
    Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {

        @Override
        public void run() {
            consumer.shutdown();
            messagingAccessPoint.shutdown();
        }
    }));
    consumer.attachQueue("OMS_HELLO_TOPIC", new MessageListener() {

        @Override
        public void onMessage(final Message message, final ReceivedMessageContext context) {
            System.out.printf("Received one message: %s%n", message.headers().getString(MessageHeader.MESSAGE_ID));
            context.ack();
        }
    });
    consumer.startup();
    System.out.printf("Consumer startup OK%n");
}

Example 2 with MessageListener

use of io.openmessaging.MessageListener in project rocketmq-rocketmq-all-4.1.0-incubating by lirenzuo.

the class PushConsumerImplTest method testConsumeMessage.

@Test
public void testConsumeMessage() {
    final byte[] testBody = new byte[] { 'a', 'b' };
    MessageExt consumedMsg = new MessageExt();
    consumedMsg.setMsgId("NewMsgId");
    consumedMsg.setBody(testBody);
    consumedMsg.putUserProperty(NonStandardKeys.MESSAGE_DESTINATION, "TOPIC");
    consumedMsg.setTopic("HELLO_QUEUE");
    consumer.attachQueue("HELLO_QUEUE", new MessageListener() {

        @Override
        public void onMessage(final Message message, final ReceivedMessageContext context) {
            assertThat(message.headers().getString(MessageHeader.MESSAGE_ID)).isEqualTo("NewMsgId");
            assertThat(((BytesMessage) message).getBody()).isEqualTo(testBody);
            context.ack();
        }
    });
    ((MessageListenerConcurrently) rocketmqPushConsumer.getMessageListener()).consumeMessage(Collections.singletonList(consumedMsg), null);
