            @MessageHeader(name = "timestamp") long timestamp,

            @MessageHeader(name = "version") String version,
            @MessageHeader(name = "country") String country,
            @MessageHeader(name = "commerce") String commerce,

            @MessageHeader(name = "capability") String capability,
            @MessageHeader(name = "mimeType") String mimeType
    );
}


String response = this.productPubSubClient.send(
                    productDto.getData(),
                    productDto.getEventId(),
                    productDto.getEventType(),
                    productDto.getEntityId(),
                    productDto.getEntityType(),
                    productDto.getTimestamp(),
                    productDto.getDatetime(),
                    productDto.getVersion(),
                    productDto.getCountry(),
                    productDto.getCommerce(),
                    productDto.getChannel(),
                    productDto.getCapability(),
                    productDto.getMimeType()
            );

it is possible to use a Map of or POJO as Headers? To avoid write multiples times @MessageHeader
