Recently, I faced up a problem in my project. I tried to use generic type in my project, but when it came to the hibernate hql, I can not get the generic type. Following is the solution:

Let’s begin

Step 1:

Suppose I have a normal class like findById.

@Override
    public User findById(Long id) {
        String hql = "FROM User u where u.id = :userId";
        Session s = sessionFactory.getCurrentSession();
        TypedQuery<User> query = s.createQuery(hql);
        query.setParameter("userId", id);
        return query.getSingleResult();
    }
