We are new to spring-boot:repackage. It's become a challenge to get Hibernate to initialize when packaged in a JAR.

The app starts up and runs as expected, when run from IntelliJ or mvn spring:boot run.

However, when we package the whole app into a nested Jar, the app starts up but Hibernate is unable to load the database driver. We see the jdbc driver in the packaged jar, and the application.properties in BOOT-INFO\classes\

On startup, we see HibernateJpaAutoConfiguration: Did not match

Do we add a Hibernate configuration class, or how should this be handled ? HibernateJpaAutoConfiguration

If there is documentation on this, please point me in that direction.

  • We would need to see some code to be able to help you. Maybe starting with pom.xml – João Dias Sep 16 '21 at 21:58
  • I think we may be running into this problem. https://stackoverflow.com/questions/20848485/spring-boot-cannot-use-persistence Should we continue to use persistence.xml or should we initialize the persistence unit differently ? The jar file doesn't contain the persistence.xml file – Kurt Van Delden Sep 17 '21 at 14:00
  • In Spring Boot you don’t need the persistance.xml to tackle common use cases. But for that you need to include spring-boot-starter-data-jpa as a dependency. With it you should remove all the orm and hibernate related dependencies. – João Dias Sep 17 '21 at 16:27
