Tomcat + OSGi + Hibernate + maven ClassNotFoundException org.hibernate.ServiceRegistry

Question

我在使用Bridge.WAR的Apache Tomcat服務器（7.0.52）中嵌入了OSGi框架。我可以使用它並在其上運行捆綁包。 我的包是使用maven構建的。

現在我想訪問數據庫並使用一個包獲取數據。我已經通過JPA批註映射了我的類，並且我想使用Hql查詢來獲取數據。對於數據訪問，我想使用休眠，我把它放在POM文件的依賴中。 我建立了mvn clean install並嵌入到OSGi容器中，我試着啓動它，但是它沒有打包org.hibernate包的類。

我不知道該如何處理它。任何人都可以幫忙嗎？我完全失去了...

我的pom.xml：

，我用這個連接：

public void setUp() throws Exception { 
     Configuration conf = new Configuration().configure("hibernate.cfg.xml"); 
     sr = new StandardServiceRegistryBuilder().applySettings(
       conf.getProperties()).build(); 
     sessionFactory = conf.buildSessionFactory(sr); 
    } 

    public void initDB() throws Exception { 

     session = sessionFactory.openSession(); 
    } 

    public void closeDB() { 
     if (session.isOpen()) 
      session.close(); 
    }

你用什麼方式嵌入你的罐子？有沒有關於錯過org.hibernate的日誌信息？我想你的OSGI容器對於hibernate包沒有任何線索。
您的<Import-Package>部分僅包含org.osgi.framework，但是如果您的包使用了org.hibernate，則還需要指定org.hibernate（有關<Import-Package>的更多詳細信息：http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html）。
