Question

我正在创建一个简单的CRUD JavaFX桌面应用程序，但它无法保存任何记录，也不会抛出错误或任何日志。
使用Hibernate 4.3.8，Netbeans 8.0.2，Java 8.
在Netbeans中生成POJO 参见代码片段
的的HibernateUtil

private static EntityManager entityManager; 
    public static EntityManager getEntityManager() {
        if (entityManager == null) {
            EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistence");
            entityManager = emf.createEntityManager();
        }
        return entityManager;
    }

UserService

@Service
    @Configurable
    public class UsersService implements IServiceInterface<Users> {
    @Override
    public Users save(Users entity) {
        return usersDAO.save(entity);
    }

UserController中

@Controller
    public class UserCtrl implements Initializable {
    private final IServiceInterface userService = new UsersService();
     public void addUser(Users user) {
        userService.save(user);
    }
    }

ViewUsers

public class ViewUsers {
    @FXML
    private TextField username;
    @FXML
    private TextField password;

     public void addUser(ActionEvent event) {
        Users user = new Users();
        user.setUserName(username.getText());
        user.setUserPass(password.getText());
        userCtrl.addUser(user);
    }
    }

View.fxml

<GridPane fx:controller="com.users.view.users" 
    xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10" vgap="10"
    styleClass="root">
    <TextField fx:id="username" GridPane.columnIndex="1" GridPane.rowIndex="1"/>
    <PasswordField fx:id="password" GridPane.columnIndex="1" GridPane.rowIndex="2"/>
    <Button text="Sign In" onAction="#addUser"/>
    </GridPane>

更新我正在使用GenericDao

final EntityManager em = HibernateUtil.getEntityManager();
     @Override
    public T save(T entity) { 
            final T savedEntity = em.merge(entity);
            return savedEntity; 
    }

JavaFx maven，MySql，Hibernate，JPA桌面应用程序：没有保存但没有错误或日志
