Hibernate 3.x中的混合屬性設置

Question

我想以編程方式使用xml文件設置休眠屬性中的幾個

到目前為止，我已經完成了下面的代碼，但是沒有用。

MyHibernateUtil.java //此類用於創建Hibernate Session Factory

          private static org.hibernate.SessionFactory sessionFactory;
          private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml";
          private static String configFile = CONFIG_FILE_LOCATION;
                    static {
    try {

        Properties prop = new Properties();
        prop.setProperty("hibernate.connection.username", userId);
        prop.setProperty("hibernate.connection.password", passCode);
        prop.setProperty("hibernate.connection.url", URL);
                  prop.setProperty("hibernate.connection.driver_class", "oracle.jdbc.driver.OracleDriver");
        prop.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect");

        annotationConfiguration.configure(configFile).setProperties(prop);;
        sessionFactory = annotationConfiguration.buildSessionFactory();

    } catch (Exception e) {
        System.err.println("%%%% Error Creating SessionFactory %%%%");
        e.printStackTrace();
    }
}

     public static org.hibernate.SessionFactory getSessionFactory() 
     //This method will return SessionFactory object
    {
    return sessionFactory;
}

在我的hibernate.cfg.xml我一直關注

hibernte.cfg.xml

   <session-factory>
<property name="dialect">
    org.hibernate.dialect.Oracle9Dialect
</property>
<property name="connection.driver_class">
    oracle.jdbc.driver.OracleDriver
</property>
<property name="hibernate.current_session_context_class">thread</property>
  <property name="show_sql">true</property>

<mapping class="Class1" />
<mapping class="Class2" />
<mapping class="Class3" />

   </session-factory>

我在正常運行的控制台應用程序中嘗試了此代碼，但是當我嘗試在Web應用程序中使用此代碼時，由於理解了Web應用程序無法創建HibernateUtil,java的對象，因此出現了一些錯誤

因此，我創建了一個Listener類，並在該類中嘗試創建SessionFactory對象，然后很幸運地得到了SessionFactory對象

但是我的問題是

當我嘗試使用URL訪問Web應用程序時，出現以下異常

以下是我的Web應用程序功能

 1)struts 2.3.x
 2)HIbernate 3.1.x

請提前幫助一些人。

編輯-

找不到相同的問題解決方案

我也有同一種，但我找不到

下課

   ServiceRegistryBuilder
   ServiceRegistrry 

 Are these classes are from Hibernate or we need to add any third party lib.

構建會話工廠時，應指定hibernare.cfg.xml位置。

/**
 * Location of hibernate.cfg.xml file.
 * Location should be on the classpath as Hibernate uses
 * #resourceAsStream style lookup for its configuration file.
 * The default classpath location of the hibernate config file is
 * in the default package. Use #setConfigFile() to update
 * the location of the configuration file for the current session.
 */
private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml";


annotationConfiguration.configure(CONFIG_FILE_LOCATION).setProperties(prop);
