Examples of org.springframework.amqp.core.Address

org.springframework.amqp.core.Address
Represents an address for publication of an AMQP message. The AMQP 0-8 and 0-9 specifications have an unstructured string that is used as a "reply to" address. There are however conventions in use and this class makes it easier to follow these conventions, which can be easily summarised as:
```
 (exchange)/(routingKey) 
```
Here we also the exchange name to default to empty (so just a routing key will work if you know the queue name). @author Mark Pollack @author Mark Fisher @author Dave Syer @author Artem Bilan

                exchange.setException(t);
            }
            
            //Send a reply if one was requested
            Address replyToAddress = amqpMessage.getMessageProperties().getReplyToAddress();
            if(replyToAddress != null) {
                org.apache.camel.Message outMessage = exchange.getOut();
                SpringAMQPMessage replyMessage = new SpringAMQPMessage(outMessage);


                // Camel exchange will contain a non-null exception if an unhandled exception has occurred,
                // such as when using the DefaultErrorHandler with default configuration, or when
                // using the DeadLetterChannel error handler with an OnException handled=false override.
                // Exchange will not contain an exception (via getException()) if the exception has been handled,
                // such as when using the DeadLetterChannel error handler with default configuration, but
                // the Exchange property EXCEPTION_CAUGHT will contain the handled exception.
                if (exchange.getException() != null) {
                    replyMessage.setHeader(SpringAMQPMessage.IS_EXCEPTION_CAUGHT, true);
