Question

我要更新用户的WHERE：

这是我的问题：

password

但没有变化！

更新

这也行不通：

@Transactional
public void resetPassInDB(String userEmail, String newPass) {

    Query query = userDao.getSession().createQuery("update User u set u.password = :password where u.email = :email");
    query.setParameter("password", newPass);
    query.setParameter("email", userEmail);
    int result = query.executeUpdate();    // is 0
}

在控制台中：

Query query = userDao.getSession().createQuery("from User where email= :email");
query.setParameter("email", userEmail);

User user = (User) query.list().get(0);
user.setPassword(newPass);
userDao.getSession().update(user);

UPDATE2

Hibernate: select user0_.id as id1_2_, user0_.email as email2_2_, user0_.password as password3_2_, user0_.username as username4_2_ from User user0_ where user0_.email=?

控制台：

@Transactional
public void resetPassInDB(String userEmail, String newPass) {
    Query query = userDao.getSession().createQuery("from User where email= :email");
    query.setParameter("email", userEmail);

    User user = (User) query.list().get(0);
    System.out.println("retrieved user: " + user);
    user.setPassword(newPass);

    userDao.getSession().update(user);
    System.out.println("updated user: " + user);
}

但Hibernate: select user0_.id as id1_2_, user0_.email as email2_2_, user0_.password as password3_2_, user0_.username as username4_2_ from User user0_ where user0_.email=? retrieved user: username: aaaa, password: llkk, email: abc@gmail.com updated user: username: aaaa, password: vvbb, email: abc@gmail.com表中没有任何变化！
