Spring 4 - Hibernate 5 - Error Creating LocalSessionFactoryBean

Question

Has been struggling for 1 night, yesterday everything is okay. I think I messed up somewhere.

Has anyone have clue where is the issue? below log is not helping me to find the culprit.

Please let me know what do you want me to share here.

Answer 1

From stacktrace you can see that it's probably related to configuration (namely, FK - foreign key - not found):

    Caused by: java.lang.NullPointerException

So, double check you entities configuration do not contain some dangling foreign keys / make sure your package scan includes all the entities.
