Example 2 with ContentTypeDelegatingMessageConverter

use of org.springframework.amqp.support.converter.ContentTypeDelegatingMessageConverter in project spring-integration by spring-projects.

the class MappingUtils method mapMessage.

/**
 * Map an o.s.Message to an o.s.a.core.Message. When using a
 * {@link ContentTypeDelegatingMessageConverter}, {@link AmqpHeaders#CONTENT_TYPE} and
 * {@link MessageHeaders#CONTENT_TYPE} will be used for the selection, with the AMQP
 * header taking precedence.
 * @param requestMessage the request message.
 * @param converter the message converter to use.
 * @param headerMapper the header mapper to use.
 * @param defaultDeliveryMode the default delivery mode.
 * @param headersMappedLast true if headers are mapped after conversion.
 * @return the mapped Message.
