JDBCConnection问题

Question

我正在使用Spring MVC和HIbernate开发一个应用程序，并尝试与10g数据库连接。

试图更改.jar文件，并检查了要配置为休眠配置的属性。

属性文件：

hibernate.connection.driver_class = oracle.jdbc.driver.OracleDriver
hibernate.connection.url = jdbc:oracle:thin:@localhost:1521:jeevan
hibernate.connection.username = jeevan
hibernate.connection.password = jeevanr123
hibernate.dialect = org.hibernate.dialect.Oracle10gDialect
hibernate.hbm2ddl.auto = create

休眠实用程序类以获取SessionFactory对象代码：

public class HibernateUtilies{
        private Configuration config = new Configuration();
    private SessionFactory factory;

    public HibernateUtilities() {
        if(this.factory == null) {
            getSessionFactory();
        }
    }

    public SessionFactory getSessionFactory() {
            if(factory  == null) {          
          StandardServiceRegistryBuilder registry = 
                                config.getStandardServiceRegistryBuilder();

                  registry.applySettings(config.getProperties());

                  return config.buildSessionFactory(registry.build());
        }
        else {
          return this.factory;
            }
         }
}

期望的描述：

连接到特定的已配置数据库。

实际结果：
