如何在 spring 集成消息中设置 JMS Header

Question

I am trying to set jms correlation id in spring integration message by setting in its header before pushing into a IBM MQ but the value Is not available after reading the message from the queue.

Using the below code to set the header

MessageBuilder.withPayload("Hi")
.setHeader(JmsConstans.JMS_CORRELATIONID,"ID12334556889").build();

We don't know what is that JmsConstans.JMS_CORRELATIONID : it is not available in my dependencies. So, sounds more like it is your own and, therefore, we have to know its value.

The logic in the DefaultJmsHeaderMapper (used by default by the JmsSendingMessageHandler ) is like this:

private void populateCorrelationIdPropertyFromHeaders(MessageHeaders headers, javax.jms.Message jmsMessage) {
    Object jmsCorrelationId = headers.get(JmsHeaders.CORRELATION_ID);
    if (jmsCorrelationId instanceof Number) {
        jmsCorrelationId = jmsCorrelationId.toString();
    }
    if (jmsCorrelationId instanceof String) {
        try {
            jmsMessage.setJMSCorrelationID((String) jmsCorrelationId);
        }
        catch (Exception ex) {
            LOGGER.info("Failed to set JMSCorrelationID, skipping", ex);
        }
    }
}

where that JmsHeaders.CORRELATION_ID has this value: jms_correlationId .

However all of this is just a speculation since e don't know how you push that message to IBM MQ...
