Ниже приведена стек, которую я получаю, когда мой сервис отдыха пытается получить большой набор данных (база данных и tomcat находятся на моей локальной машине, поэтому все локально). Он работает на небольших, но в некоторых случаях пользователь хочет много данных. Я проверил аналогичные проблемы, размещенные здесь, но, похоже, не похоже на мое.Установленное соединение было прервано программным обеспечением вашего хост-компьютера. Tomcat jackson
Мои вопросы:
1. Почему он не отображает ответ?
2. Размер ответа ограничен каким-то образом на tomcat? Может быть, есть тайм-аут или что-то в этом роде?
3. Возможно, это джексон, который не выполняет свою работу. Если это джексон - это может быть вызвано аннотациями типа @JsonBackReference и @JsonManagedReference?
4. Что я могу сделать, чтобы исправить это?

ниже код (контроллер), который возвращает ответ клиента:
@RequestMapping(method = RequestMethod.GET)
@ResponseBody
public String getSelections(@RequestParam Integer systemId, @RequestParam String listCode)
throws JsonProcessingException {
SelectionsDTO selectionsDTO = new SelectionsDTO(systemSelectionService.findSelections(systemId, listCode));
String retVal = objectMapper.writeValueAsString(selectionsDTO);
return retVal;
}
, как вы можете видеть, что я даже пытался Маршалл его для того чтобы строки, прежде чем вернуться, чтобы исключить Джексон как причина неудачи. Неважно, возвращаю ли я коллекцию своих DTO или строк. Это не так. Я отлаживал его, и я проверил размер сообщения, которое было написано для вывода успешно (это около 2,15 МБ). По моему мнению, размер сообщения является причиной отказа.
