Example 1 with AutoFinishScope

use of io.opentracing.util.AutoFinishScope in project opentracing-java by opentracing.

the class RunnableAction method run.

/**
 * Can be used continuation.activate().deactivate() chain only. It is splitted for testing
 * purposes (span should not be finished before deactivate() called here).
 */
@Override
public void run() {
    logger.info("Action started");
    AutoFinishScope scope = continuation.activate();
    try {
        // without sleep first action can finish before second is started
        TimeUnit.SECONDS.sleep(1);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    // set random tag starting with 'test_tag_' to test that finished span has all of them
    scope.span().setTag("test_tag_" + ThreadLocalRandom.current().nextInt(), "random");
    scope.close();
    logger.info("Action finished");
}

                try (Scope subtaskScope = tracer.buildSpan("subtask").startActive(false)) {
                    // Simulate work.
                    sleep(milliseconds);
