Question

我想用编程方式设置hibernate属性，其中很少使用xml文件

到目前为止，我已经完成了下面的代码但是没有用。

MyHibernateUtil.java //这个类是创建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;
}

并在hibernate.cfg.xml我一直关注

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>

我尝试使用运行良好的控制台应用程序代码，但是当我尝试在我的Web应用程序中使用此代码时，我发现一些错误，因为我理解Web应用程序无法创建我的{{1}的对象}

所以我创建了一个Listener类，在那个类中我尝试创建HibernateUtil,java Object，然后幸运的是我得到了SessionFactory对象

但我的问题是

当我尝试使用SessionFactory访问我的网络应用程序时，我遇到了以下异常

以下是我的网络应用程序功能

您应该在构建会话工厂时指定hibernare.cfg.xml的位置。

/**
 * 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);
