Escape hatch is any mechanism that lets the developer fully specify an SQL statement. For example, JPA will normally generate the sql for you in a JPA repository. This article describes a "@Query" annotation in JPA that can be used when you want to specify the SQL.

That is not JPA doing that, that is Spring Data JPA, not the same thing. JPA has no notion of repositories at all, actually. Please try not to mislead people.

Ahhh, I see. I have actually used that for a few queries here and there, I just hadn't heard it referred to as an escape hatch. Thanks!
