Question

 public User findUser(String email) {
                User user = null;
                user = (User) sessionFactory.getCurrentSession().createCriteria(User.class).add(Restrictions.eq("email", email)).uniqueResult();

                return user;

        }

现在我想添加一个限制，好像active is 1我该怎么做。我找不到任何可以检查两个限制的方法请建议罗米。

Answer 1

add(Criteria)方法返回自身（this）以允许链接。

public User findUser(String email) {
    User user = null;
    Criteria c = sessionFactory.getCurrentSession().createCriteria(User.class);

    //You can chain the add method, because it returns `this`.
    c = c.add(Restrictions.eq("email", email)).add(Restrictions.eq("active", 1));
    return (User) c.uniqueResult();
}
