    • 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.

      Set the default delivery mode.
      Parameters:
      defaultDeliveryMode - the delivery mode.
    • setLazyConnect

      public void setLazyConnect(boolean lazyConnect)
      Set to false to attempt to connect during endpoint start; default true, meaning the connection will be attempted to be established on the arrival of the first message.
      Parameters:
      lazyConnect - the lazyConnect to set
      Since:
      4.1
    • setDelay

      public void setDelay(int delay)
      Set the value to set in the x-delay header when using the RabbitMQ delayed message exchange plugin. By default, the AmqpHeaders.DELAY header (if present) is mapped; setting the delay here overrides that value.
      Parameters:
      delay - the delay.
      Since:
      4.3.5
    • setDelayExpression

      public void setDelayExpression(Expression delayExpression)
      Set the SpEL expression to calculate the x-delay header when using the RabbitMQ delayed message exchange plugin. By default, the AmqpHeaders.DELAY header (if present) is mapped; setting the expression here overrides that value.
      Parameters:
      delayExpression - the expression.
      Since:
      4.3.5
    • setDelayExpressionString

      public void setDelayExpressionString(@Nullable String delayExpression)
      Set the SpEL expression to calculate the x-delay header when using the RabbitMQ delayed message exchange plugin. By default, the AmqpHeaders.DELAY header (if present) is mapped; setting the expression here overrides that value.
      Parameters:
      delayExpression - the expression.
      Since:
      4.3.5
    • setErrorMessageStrategy

      public void setErrorMessageStrategy(ErrorMessageStrategy errorMessageStrategy)
      Set the error message strategy to use for returned (or negatively confirmed) messages.
      Parameters:
      errorMessageStrategy - the strategy.

    • 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.
      Parameters:
      confirmTimeout - the approximate timeout.
