Class DefaultAmqpHeaderMapper

java.lang.Object
  org.springframework.integration.mapping.AbstractHeaderMapper<org.springframework.amqp.core.MessageProperties>
      org.springframework.integration.amqp.support.DefaultAmqpHeaderMapper

All Implemented Interfaces:

AmqpHeaderMapper, RequestReplyHeaderMapper<org.springframework.amqp.core.MessageProperties>

public class DefaultAmqpHeaderMapper
extends AbstractHeaderMapper<org.springframework.amqp.core.MessageProperties>
implements AmqpHeaderMapper

Default implementation of AmqpHeaderMapper.

By default this implementation will only copy AMQP properties (e.g. contentType) to and from Spring Integration MessageHeaders. Any user-defined headers within the AMQP MessageProperties will NOT be copied to or from an AMQP Message unless explicitly identified via 'requestHeaderNames' and/or 'replyHeaderNames' (see AbstractHeaderMapper.setRequestHeaderNames(String[]) and AbstractHeaderMapper.setReplyHeaderNames(String[])} as well as 'mapped-request-headers' and 'mapped-reply-headers' attributes of the AMQP adapters). If you need to copy all user-defined headers simply use wild-card character '*'.

Constants for the AMQP header keys are defined in AmqpHeaders.

2.1
