什么类型的对象“在主题查询中返回结果（）”

Question

When I execute query using find(id) then it works OK.
But when I use createQuery method like

select u from User u where u.id = 1 then I get error that it is an array.

So I want to know if it always returns an array even if the result is 1?

I tried getMaxResults(1) but I get the same error

The getResult() method returns an array of results. If you're querying for just one object, you can use the getSingleResult() method instead:
