У меня есть комплект OSGI в JBoss Fuse 6.2, который импортирует банку с сущностями и классами dao.
Jar содержит:
Spring.xmlJBoss Fuse + JPA/Hibernate

класс Dao

@Repository 
@Transactional 
public class JpaEntityDao implements EntityDao { 

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

    //methods that use EntityManager 
}

Entity Класс

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

Я хочу использовать JpaEntityDao в своем пакете. я импортировал spring.xml из кувшина, чтобы связать пружинную XML

Когда я устанавливаю сверток Karaf появляется какая-то ошибка:

Кажется, что Karaf находит определение класса в persistence.xml, но не может загрузить Entity класс.
Любые предложения приветствуются.

У вас есть возможность решить эту проблему? Если да, можете ли вы поделиться информацией. Я также сталкиваюсь с аналогичной проблемой :( – casper

см. Мой комментарий ниже, он работает. Вы можете увидеть примеры. – user3017797

Поскольку сущность импортируется из другой банки и загружается пакетом через EntityManager, вам, вероятно, потребуется собрать банку в виде пакета и экспортировать пакеты, а затем импортировать пакеты с помощью `maven-bundle-plugin ' например

Jar:

<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>

OSGi Bundle:

<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 расслоение, экспорт с использованием packages:imports, packages:exports. Было бы даже лучше создать функцию, которая определяет связки, от которых она зависит.
