java - Hibernate 返回查询结果

Question

 public Users loginUser(String username,String password)
{
    Users user;
    org.hibernate.Transaction tx = session.beginTransaction();
    Query q = session.createQuery("from Users as users where Username ="+ username + " && Password = " +password);
    user = (Users) q.uniqueResult();
    return user;
}

我正在尝试返回尝试登录的用户，但它在调用上述方法的行中给了我一个错误。

org.apache.jasper.JasperException: An exception occurred processing JSP page /loginlogout.jsp at line 21

我认为您可以尝试以下查询：

Query q = session.createQuery("from Users as users where users.Username=:username and users.Password=:password") ;
