有關使用休眠的Oracle JDBC的問題...有時候

我能夠在運行JUnit測試時成功連接和管理實體，但是一旦啓動我的實際應用程序，就會收到「未找到指定的JDBC驅動程序oracle.jdbc.OracleDriver類」。

讓我感到困惑的是它在那裏。它運行我的JUnit測試時，它工作。

感謝您的任何見解！

的hibernate.cfg.xml

<?xml version="1.0" encoding="utf-8"?> 

<!DOCTYPE hibernate-configuration PUBLIC 
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

    </session-factory> 
</hibernate-configuration>

HibernateUtil.java

package org.util; 

import org.hibernate.SessionFactory; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.service.*; 

public class HibernateUtil { 

    private static SessionFactory sessionFactory = buildSessionFactory(); 

    private static SessionFactory buildSessionFactory() { 
     try { 
      // Create the SessionFactory from hibernate.cfg.xml 
      Configuration configuration = new Configuration(); 
      configuration.configure(); 
      ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
       configuration.getProperties() 
      ).buildServiceRegistry(); 
      sessionFactory = configuration.buildSessionFactory(serviceRegistry); 
      return sessionFactory; 
     } catch (Throwable ex) { 
      // Exception thrown here! 
      System.err.println("Initial SessionFactory creation failed." + ex); 
      throw new ExceptionInInitializerError(ex); 
     } 
    } 

    public static SessionFactory getSessionFactory() { 
     return sessionFactory; 
    } 

    public static void shutdown() { 
     // Close caches and connection pools 
     getSessionFactory().close(); 
    } 

}

我發現我的問題。低於我的pom.xml我有這個小片段

<dependency> 
    <groupId>org.hibernate.common</groupId> 
    <artifactId>hibernate-commons-annotations</artifactId> 
    <version>4.0.1.Final</version> 
    <classifier>tests</classifier> 
</dependency>

分類器只能訪問我的測試套件。刪除分類器解決了問題。

<dependency> 
    <groupId>org.hibernate.common</groupId> 
    <artifactId>hibernate-commons-annotations</artifactId> 
    <version>4.0.1.Final</version> 
</dependency>
