public final class JpaUtils
extends Object
This Utility contains a sub-set of utility methods from the Spring Data JPA Project. As the Spring Integration JPA adapter uses only these utility methods, they were copied into this class in order to prevent having to declare a dependency on Spring Data JPA.
