У меня есть следующий код -
PdfRequest pdfRequest = new PdfRequest();
pdfRequest.setAppName("abc"));
pdfRequest.setId("D342");
String pdfRequestJson = mapper.toJson(pdfRequest);
producerTemplate.requestBodyAndHeaders("direct:sendRoute", pdfRequestJson,
null, String.class); //line number 154
Конфигурация маршрута такая же: -
from("direct:sendRoute")
.setExchangePattern(ExchangePattern.InOnly)
.log("Sending data ${body} to queue") . //this log was never printed
.toF("pdfQueueProducerBean:topic://%s", topicName)
.end();
mapper - это gson bean в указанном выше случае
Но покапри выполнении этого кода я получаю следующую ошибку -

Очевидно, что мое тело обмена не является нулевым, так как объект создается непосредственно перед его отправкой черезsellerTemplate (и ManufacturerTemplate было автоматически подключено с конфигурацией по умолчанию, если это имеет значение)
