I solved my self.
It was the cause that I didn't set to SqlSchema of CacheConfigration.
Please tell me in connection with this.
I don't know which instance query() method should be called.

Thank you for your reply.
In addition to this, I want to know how to use SqlFieldsQuery instead of
SqlQuery.
I would like you to teach me about that.
My code is here.

I call QueryEntity#addQueryField("id", String.class.get
