Neo4j Embedded база данных зависает после аварийного завершения приложения
Я собираюсь сделать свое первое приложение на базе базы данных Neo4j Embedded общедоступным и столкнулся с серьезной проблемой блокировки -
Это мой предыдущий вопрос с удалением базы данных, где я столкнулся с этой проблемойЭффективно очистить базу данных Neo4j
Я использую:
OS: Windows 8.1
jdk1.8.0_51
neo4j version 2.2.3
lucene version 3.6.2
spring-data-neo4j version 3.4.0.M1
Я заметил, что все работает правильно, если я используюgraphDatabaseService.shutdown(); перед завершением работы моего приложения. В противном случае база данных уничтожается (не только мое приложение, но даже сервер Neo4j также зависает на этой поврежденной базе данных, когда я пытаюсь загрузить встроенную базу данных с веб-интерфейсом Neo4j).
Можно ли сделать базу данных Neo4j Embedded более отказоустойчивой? Я потеряю все свои данные после первой ошибки (например, затемнения) в производственной среде.
Я потратил несколько дней на эту проблему, но до сих пор не знаю, как ее решить. Пожалуйста помоги.

ОБНОВЛЕНО
Я нашел общий источник этой проблемы, но сейчас не знаю, как это исправить.
Это моеWebSecurityConfig:
@Configuration
@EnableWebSecurity
@EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private SocialAuthenticationSuccessHandler socialAuthenticationSuccessHandler;
@Autowired
private TokenAuthenticationService tokenAuthenticationService;
@Autowired
private TokenAuthenticationFilter tokenAuthenticationFilter;
@Autowired
private DBUserDetailsService userDetailsService;
.....
}
Я автоматически связал 4 поля, которые внутренне используют Neo4j (DAO, репозитории и т. Д.). Neo4j зависает при перезапуске после нечистого выключения, когда эти поля присутствуют внутри моего WebSecurityConfig. Когда я комментирую эти поля, проблема исчезает.
Что может быть не так?
