Create an Address given the exchange name and routing key.

Usage

From source file:org.springframework.amqp.rabbit.listener.adapter.AbstractAdaptableMessageListener.java

/**
 * Determine a reply-to Address for the given message.
 * <p>/*from  w  ww.  jav  a  2  s . c  o m*/
 * The default implementation first checks the Rabbit Reply-To Address of the supplied request; if that is not
 * <code>null</code> it is returned; if it is <code>null</code>, then the configured default response Exchange and
 * routing key are used to construct a reply-to Address. If the responseExchange property is also <code>null</code>,
 * then an {@link org.springframework.amqp.AmqpException} is thrown.
 * @param request the original incoming Rabbit message.
 * @param source the source data (e.g. {@code o.s.messaging.Message<?>}).
 * @param result the result.
 * @return the reply-to Address (never <code>null</code>)
 * @throws Exception if thrown by Rabbit API methods
 * @throws org.springframework.amqp.AmqpException if no {@link Address} can be determined
 * @see #setResponseAddress(String)
 * @see #setResponseRoutingKey(String)
 * @see org.springframework.amqp.core.Message#getMessageProperties()
 * @see org.springframework.amqp.core.MessageProperties#getReplyTo()
