Answer 1

sql语句问题，贴出来吧，建议先执行下sql，没有问题在写到程序中

Answer 2

sql语句错了，还是现在数据库里边执行下sql语句

Answer 3

执行sql的时候不对,看些日志下面的sql语句,复制到数据库改一下执行试试

Answer 4

public Users checkUsers(Users users){
String hql = "from Users where username = ? and password = ?";
String[] parameters = {users.getUsername(), users.getPassword()};
List<Users> list = HibernateUtil.executeQuery(hql, parameters);
if(list.size() == 0){
return null;
}else{
return list.get(0);
}
}

Answer 5

控制台显示的select语句username和password都有值吗

Answer 6

不用看了，这个异常很平常见。是Sql语法有问题的

Answer 7

我sql语句就那么一条啊，找也要有找的地方撒String hql = "from Users where username = ? and password = ?";
