    • setPayloadTypeMapper

      public void setPayloadTypeMapper(Function<Message<?>,Class<?>> payloadTypeMapper)
      Set the payload type mapper to be used by this converter. Message payloads will be converted to the Class returned by this function. The defaultHeaderTypeMapping(org.springframework.messaging.Message<?>) uses the typeHeader property to retrieve the payload class' FQCN. This method replaces the default type mapping for this converter instance.
      Parameters:
      payloadTypeMapper - the type mapping function.

    • setPayloadMessageConverter

      public void setPayloadMessageConverter(MessageConverter messageConverter)
      Set the MessageConverter to be used for converting the Message instances payloads.
      Parameters:
      messageConverter - the converter instance.

    • setObjectMapper

      public void setObjectMapper(com.fasterxml.jackson.databind.ObjectMapper objectMapper)
      Set the ObjectMapper instance to be used for converting the Message instances payloads.
      Parameters:
      objectMapper - the object mapper instance.

    • getPayloadMessageConverter

      public MessageConverter getPayloadMessageConverter()
      Get the MessageConverter to be used for converting the Message instances payloads.
      Returns:
      the instance.

    • setPayloadTypeHeader

      public void setPayloadTypeHeader(String typeHeader)
      Set the name of the header to be looked up in a Message instance by the defaultHeaderTypeMapping(Message).
      Parameters:
      typeHeader - the header name.

    • setPayloadTypeHeaderValueFunction

      public void setPayloadTypeHeaderValueFunction(Function<Message<?>,String> payloadTypeHeaderFunction)
