会话工厂关闭异常，结果集耗尽，休眠会话工厂中出现异常

Question

休眠会话工厂配置代码：-

静态会话session = null;公共静态会话getSession（Class clazz）{

            try {

                Configuration cfg = new Configuration().configure().addAnnotatedClass(clazz);

                StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
                        .applySettings(cfg.getProperties());

                SessionFactory sf = cfg.buildSessionFactory(builder.build());

                Session session = sf.openSession();
                return session;
            } catch (Exception e) {
                logger.info("Error in creating session with Database", e);
            }

            return null;
        }



    public static <T> List<T> findAll(Class<T> clazz) {
            try {
                session = getSession(clazz);
                session.beginTransaction();
                List<T> result = session.createQuery("from " + clazz.getName()).list();         

                return result;
            } catch (Exception e) {
                logger.info("Error at <T> List<T> findaAll in creating session with the DataBase " +e.getMessage() + " the class is " +clazz);


            } finally {
                if (session != null && session.isOpen()) {
                    session.close();
                }
            }
            return new ArrayList<>();
        }

会话关闭的异常主要是在多次刷新中出现的：-

and here is the result exhausted Exception which is coming in my code:-

仅从getSession（）方法返回sessionFactory。

class Util{
    public static SessionFactory getSession(Class clazz) {
    try {
         Configuration cfg = new Configuration().configure().addAnnotatedClass(clazz);
         StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
                            .applySettings(cfg.getProperties());
         SessionFactory sf = cfg.buildSessionFactory(builder.build());
         return sf;
       } catch (Exception e) {
         logger.info("Error in creating session with Database", e);
       }
    }
}

现在在findAll（）方法中：

try (Session session = Util.getSession(clazz).openSession()) {
    // start a transaction
   transaction = session.beginTransaction();
    //rest of code

}catch(Exception ex){
}

这可能有效.. !!
