  public AbstractAmqpOutboundEndpoint()
Method Details
- setHeaderMapper
  
  public void setHeaderMapper(AmqpHeaderMapper headerMapper)
  
  Set a custom AmqpHeaderMapper for mapping request and reply headers. Defaults to DefaultAmqpHeaderMapper.outboundMapper().
  
  Parameters:
  
  headerMapper - the AmqpHeaderMapper to use.
- setHeadersMappedLast
  
  public void setHeadersMappedLast(boolean headersMappedLast)
  
  When mapping headers for the outbound message, determine whether the headers are mapped before the message is converted, or afterwards. This only affects headers that might be added by the message converter. When false, the converter's headers win; when true, any headers added by the converter will be overridden (if the source message has a header that maps to those headers). You might wish to set this to true, for example, when using a SimpleMessageConverter with a String payload that contains json; the converter will set the content type to text/plain which can be overridden to application/json by setting the AmqpHeaders.CONTENT_TYPE message header. Default: false.
  
  Parameters:
  
  headersMappedLast - true if headers are mapped after conversion.
  
  Since:
  
  5.0

- setConfirmTimeout
  
  public void setConfirmTimeout(long confirmTimeout)
  
  Set a timeout after which a nack will be synthesized if no publisher confirm has been received within that time. Missing confirms will be checked every 50% of this value so the synthesized nack will be sent between 1x and 1.5x this timeout.
