Spring 3 MVC + Hibernate. Data editing?

Question

Hibernate

Hello.
I tried to make my web application using this article. But when I decided to attach data editing to it, I got stuck. My problem is similar to this one . Can anyone give a simple example with data editing? Thanks in advance.

The easiest method in this case is to use Query Update. Something like: "UPDATE User u SET u.name=:name where u.id = :id" In this case, changes the content of one field (name in the example) according to the existing field (id). But as for me it is more convenient to use not the SessionFactory, but the EntityManager, then the code in the repository will be like this:

  @PersistenceContext
  private EntityManager entityManager;

  public void updateUser(User user) {
    entityManager.merge(user);
  }
