Spring 4 + Hibernate 5 = org.springframework.orm.jpa.EntityManagerHolder kann nicht in org.springframework.orm.hibernate5.SessionHolder umgewandelt werden

Question

OK, ich bin ein absoluter Anfänger, wenn es darum geht, ein neues Java-Projekt zu starten und zu integrieren Werkzeuge wie Frühling/Winterschlaf usw. Tatsächlich ist dies das erste Mal, dass ich es mache. Ich bin sicher, der Fehler wird für euch offensichtlich sein.

Guessings:

• Die Sitzung Fabrik ich nicht das erwartete ist durch eine Feder eingespritzt wird.
• Falsche Abhängigkeiten.

Haben Sie verwenden Frühling-Boot? In meinem Fall war das Problem mit @EnableAutoConfiguration - verwenden Sie exclude = HibernateJpaAutoConfiguration.class
