Я разрабатываю систему, которая будет читать и обрабатывать файлы из каталога. Как только весь файл будет обработан, он вызовет метод, который, в свою очередь, создаст файл. Кроме того, он должен маршрутизировать / обрабатывать файлы на основе имени файла, я использовал Spring интеграции маршрутизатора для того же. Ниже приведен фрагмент кода Интеграции. Мой вопрос заключается в том, что это не работает, если я удаляю какую-либо строку .channel(aggregatorOutputChannel())
или .channel(confirmChannel())
, также я должен сохранить тот же канал .channel(aggregatorOutputChannel())
до и после агрегатора. Зачем мне все 3 канала объявления? если это не так, как это исправить.
Я использую JDK 8, Spring 5, Spring boot 2.0.4.
