Я использовал:
Spring MVC-версия: 4.3.7 Postgres: 9,5 Инструмент: STS
мой дао:
@Transactional(propagation = Propagation.REQUIRED, readOnly = false)
public void updatedivision(Division p) {
Session session = this.sessionFactory.getCurrentSession();
Query query = session.createQuery("update Division set name =:name where id = :id ");
query.setParameter("name", p.getName());
query.setParameter("id", p.getId());
int result = query.executeUpdate();
session.flush();
System.out.println("Division updated successfully, Division Details=" + p.getName());
Я хочу обновить свою базу данных.Но после ввода в форму. Но когда я запускаю код, обновленное значение получено правильно (я проверил, напечатав значение.) Но Таблица не обновляется.

Но он не показывает никакой ошибки. Вот моя модель:
@Entity
@Table(name = "division")
public class Division implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="id")
private Integer id;
@Column(name="name")
private String name;
Мой стол:
CREATE TABLE public.division
(
id integer NOT NULL,
name character varying(20) NOT NULL,
CONSTRAINT division_pkey PRIMARY KEY (id)
)
