Class JpaAdapter

java.lang.Object

org.springframework.data.jpa.util.JpaAdapter

public abstract class JpaAdapter
extends Object

Creates queries from an EntityManager in a way that stays binary-compatible across Jakarta Persistence API generations.

Jakarta Persistence 4 changes the return type of the untyped query factory methods, so code compiled against 3.2 fails with a NoSuchMethodError when running against 4 and therefore we're falling back tom reflection.

Since:

4.2
