Ява.яз..Исключение NullPointerException при внедрении EntityManager в репозиторий Spring
Я новичок в Spring MVC. Я уже несколько дней ищу решение своей проблемы, но безуспешно.
Вот мой стек:
- JBoss 4.2.3 GA сервер
- Я знаю, что это очень старая версия, но именно этим я сейчас и ограничиваюсь. jBoss 7.1 будет одобрен для использования в моей организации в течение ближайших нескольких месяцев, но я хотел бы, чтобы мое приложение R&D работало на сервере 4.2.3 GA. Это означает, что я добавил все необходимые банки в мой / lib папка.
Мой проект структура:
-
Src
-
Baseproject
- модель
- безопасность
- пользователь.java
- роль.java
- ... другие компоненты сущности, связанные с безопасностью
- безопасность
-
Репозиторий
- безопасность
- UserRepository.java
- UserRepositoryImpl.java
- роль опосредованная.java
- RoleRepositoryImpl.java
- ... другие связанные с безопасностью хранилища
- безопасность
-
Служба
- Служба безопасности.java
- SecurityServiceImpl.java
- web
- контроллер
- UserController.java (типичный контроллер)
- конфигурация
- WebConfig.java (основная конфигурация сервлета)
- PersistenceConfig.java (все, что связано с персистентностью. Думаю, именно в этом и заключается моя проблема... нет стойкость.xml)
- контроллер
- модель

Спасибо за помощь.
4 ответа:
Я знаю, что этому вопросу уже больше 9 месяцев, но я наткнулся на ту же проблему и сумел ее решить. Решение от Андрея Стефана - это один шаг в правильном направлении. Удивительно, но когда вы вызываете getObject () в методе для извлечения entityManagerFactory, он вызовет NPE, но если вы вызовете точно такой же метод вне метода entityManagerFactory, он будет работать.
@Bean public PlatformTransactionManager transactionManager() { return new JpaTransactionManager(entityManagerFactory().getObject()); } @Bean public LocalContainerEntityManagerFactoryBean entityManagerFactory() { LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean(); factory.setDataSource(dataSource()); HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter(); jpaVendorAdapter.setGenerateDdl(true); jpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.H2Dialect"); factory.setJpaVendorAdapter(jpaVendorAdapter); return factory; } @Bean public DataSource dataSource() { return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).build(); }
Логика инициализации
LocalContainerEntityManagerFactoryBean
находится в методеafterPropertiesSet()
. Обычно он вызывается весной после того, как все свойства были установлены. Вы должны вызватьafterPropertiesSet()
перед вызовомgetObject()
, Если вы вручную создаете экземпляр Боба. В противном случае вы получитеNullPointerException
.
