            });
        } catch (Exception e) {
            LOG.error("Async send message failure!", e);
        }
    } else {
        // sync sending, will return a SendResult
        try {
            SendResult result = producer.send(msg);
            LOG.debug("Sync send message result: {}", result);

Example 2 with SendCallback

use of org.apache.rocketmq.client.producer.SendCallback in project spring-boot-starter-samples by vindell.

the class SimpleAsyncProducer method main.

public static void main(String[] args) throws Exception {
    // Instantiate with a producer group name.
    DefaultMQProducer producer = new DefaultMQProducer("ExampleProducerGroup");
    // Launch the instance.

    producer.setRetryTimesWhenSendAsyncFailed(0);
    for (int i = 0; i < 100; i++) {
        final int index = i;
        // Create a message instance, specifying topic, tag and message body.
        Message msg = new Message("TopicTest", "TagA", "OrderID188", "Hello world".getBytes(RemotingHelper.DEFAULT_CHARSET));
        producer.send(msg, new SendCallback() {

            @Override
            public void onSuccess(SendResult sendResult) {
                System.out.printf("%-10d OK %s %n", index, sendResult.getMsgId());
            }

            @Override
            public void onException(Throwable e) {
                System.out.printf("%-10d Exception %s %n", index, e);
                e.printStackTrace();
            }
        });
    }
    // Shut down once the producer instance is not longer in use.
    producer.shutdown();
