Package org.springframework.integration.amqp.support

Class DefaultAmqpHeaderMapper

java.lang.Object

org.springframework.integration.mapping.AbstractHeaderMapper<MessageProperties>

org.springframework.integration.amqp.support.DefaultAmqpHeaderMapper

All Implemented Interfaces:

Aware, BeanClassLoaderAware, AmqpHeaderMapper, RequestReplyHeaderMapper<MessageProperties>

public class DefaultAmqpHeaderMapper
extends AbstractHeaderMapper<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.

Since:

2.1
