use of com.odysseusinc.arachne.commons.service.messaging.ConsumerTemplate in project ArachneCentralAPI by OHDSI.

the class BaseDataNodeMessagingController method getEntityRequests.

@RequestMapping(value = "/api/v1/data-nodes/entities", method = GET)
public List<CommonEntityRequestDTO> getEntityRequests(Principal principal) throws PermissionDeniedException, JMSException {
    DataNode dataNode = getDatanode(principal);
    final String requestQueue = getRequestQueueName(MessagingUtils.Entities.getBaseQueue(dataNode));
    ConsumerTemplate consumerTpl = new ConsumerTemplate(destinationResolver, requestQueue, // Give some time for case when new connection to a broker is established
    1000L);
    List<CommonEntityRequestDTO> cohortRequests = new ArrayList<>();
    while (true) {
        ObjectMessage requestMessage = jmsTemplate.execute(consumerTpl, true);
        if (requestMessage == null) {
            break;
        }
        final CommonEntityRequestDTO cohortRequest = (CommonEntityRequestDTO) requestMessage.getObject();
        cohortRequest.setId(requestMessage.getJMSCorrelationID());
        cohortRequests.add(cohortRequest);
    }
    return cohortRequests;
}
