休眠不终止

Question

问题是，一旦通过登录启动休眠模式，我将无法完全终止该程序，在Eclipse中，我必须在关闭程序后手动使用终止选项，并且作为可执行jar，该程序仍会作为Java进程保持打开状态关闭时。

这是登录类使用的方法：

public class LoginService {

private User user = null;

// email = username

public User getUser(String email) throws Exception {
    List<User> userList = new ArrayList<>();

    Session session = ConnectionHelper.getSessionFactory().openSession();   // Creates session

    CriteriaBuilder builder = session.getCriteriaBuilder();                 // Create builder
    CriteriaQuery<User> query = builder.createQuery(User.class);            // Create query
    Root<User> userRoot = query.from(User.class);                           // SELECT FROM USER
    query.where(builder.equal(userRoot.get("email"), email));               // WHERE EMAIL = ????
    userList = session.createQuery(query).getResultList();                  // Runs the query, gets result


    if (userList.size()>0) {                                                // Checks for null value
        user = userList.get(0);                                             // Gets value if not null
    }


        return user;                                                        // Returns user object

}

}

并且此类具有连接信息：

public class ConnectionHelper {

private static SessionFactory sessionFactory = null;
private static ServiceRegistry registry;

public static SessionFactory getSessionFactory() {
    if (sessionFactory == null) {
        createSessionFactory();
    }
    return sessionFactory;

}

private synchronized static void createSessionFactory() {
    Configuration config = new Configuration().configure("/res/hibernate.cfg.xml");
    config.addAnnotatedClass(User.class);
    registry = new StandardServiceRegistryBuilder().applySettings(
            config.getProperties()).build();
    sessionFactory = config.buildSessionFactory(registry);

}

public void stop() throws Exception {
    sessionFactory.close();
}

}

我曾尝试在登录服务方法中使用session.close，其中对用户/密码进行了身份验证，但这没有用。
