Наконец-то я смог создать экземпляр сервера в своем приложении Java, которое использует встроенную базу данных, как описано here. Это работает правильно, пока я запускаю его из Eclipse, но на самом деле это не моя цель (мое приложение, между прочим, кормит базу данных новыми узлами и отношениями). У меня есть блок Neo4j, который должен быть моим экземпляром сервера, и я хочу развернуть мое приложение там как файл JAR. Таким образом, я хотел бы получить доступ к веб-интерфейсу оттуда. Я уже тестировал его: при запуске приложения java на моей машине разработки любая машина в той же частной сети может без проблем получить доступ к интерфейсу. Проблема возникает при попытке упаковать все в JAR для распространения сервера.Данные Spring Neo4j: использование сервера Neo4j со встроенной: упаковка JAR
Конкретное стек ошибка выглядит следующим образом:

Я должен сказать, что я довольно новыми для Spring, Maven и сам Neo4j. Я совершенно потерял, как избавиться от этой проблемы. Веб-интерфейс фактически загружается, но без какой-либо функциональности. См. Прилагаемый снимок:
.
Бэкэнд моего приложения прекрасно работает, несмотря на эту проблему, и фактически создаются новые узлы/отношения.
Я думаю, что этот вопрос (или его вид) обсуждался here, но ответ мне непонятен.
Любые предложения? Заранее спасибо!
