Предохранитель JBoss + JPA/гибернация

У меня есть пакет OSGI в JBoss Fuse 6.2, который импортирует jar с сущностями и классами dao.
Jar содержит:
Spring.xml

Дао класс

@Repository
@Transactional
public class JpaEntityDao implements EntityDao {

    @PersistenceContext(unitName="jpaData")
    private EntityManager em;

    //methods that use EntityManager
}

Класс сущности

@Entity
@Table(name="entity", schema="public")
public class Entity {
   //fields with setters and getters
}

Я хочу использовать JpaEntityDao в своем комплекте. Я импортировал spring.xml из jar в spring xml пакета

Когда я устанавливаю бандл в Karaf, появляется ошибка:

Похоже, что Karaf находит определение класса в файле persistence.xml, но не может загрузить класс Entity.
Приветствуются любые предложения.

Удалось ли вам решить эту проблему? Если да, то не могли бы вы поделиться подробностями. Я тоже столкнулся с подобной проблемой :(   -  person casper    schedule 13.12.2016

Кажется, что spring - плохой выбор для osgi, и это было подтверждено там osgi">Использование Blueprint и Spring (не spring-dm) с OSGi.

Так что надо использовать Apache Aries. Вы можете найти рабочий пример jpa+fuse здесь https://github.com/pires/fabric8-persistence-hibernate
https://github.com/FuseByExample .

Поскольку объект импортируется из другого jar и загружается пакетом через EntityManager, вам, вероятно, потребуется собрать jar как пакет и экспортировать пакеты, а затем импортировать пакеты с помощью `maven-bundle-plugin', например

Банка:

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
        <instructions>
            <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
            <Import-Package />
            <DynamicImport-Package>*</DynamicImport-Package>
            <Export-Package>com.company.model.*</Export-Package>
        </instructions>
    </configuration>
</plugin>

Пакет OSGi:

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
        <instructions>
            <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
            <Import-Package>com.company.model.entity</Import-Package>
            <DynamicImport-Package>*</DynamicImport-Package>
            <Export-Package />
        </instructions>
    </configuration>
</plugin>

Вы можете проверить импорт и экспорт пакетов, используя packages:imports, packages:exports. Было бы еще лучше создать функцию, определяющую пакеты, от которых она зависит.
