Adding jpa/hibernate @Entity in submodule in playframework to entity manager to scan

Question

I have problem with hibernate entity while working with submodules in playframework.

Normally (in single app without submodules) I've used that code:

package models;
    @Entity
    public class AppMode {
        public static AppMode getCurrentConfigurationEntry() {
            return JPA.em().find(AppMode.class, 1L);
        }
    }

But now I have to tell hibernate entity manager to scan submodules models, cause I'm getting an error:

[IllegalArgumentException: Unknown entity: AppMode]

My model class in submodule is in package:

package models.common;

I've already tried:

        return JPA.em().find(models.common.AppMode.class, 1L);
        return JPA.em().find(common.models.AppMode.class, 1L);

but I'm getting the same error:

[IllegalArgumentException: Unknown entity: models.common.AppMode]

My question is: How to configure hibernate in play subproject to add submodules models class to classpath at runtime?

I have in both build.sbt files declared libraryDependencies with hibernate.

Should I have persistence.xml file/configuration for each module?

I think that your problem is about JPA configuration. Check this this answer which explains JPA multi-module configuration.

Good luck!

It dosn't helped me at all. I know I have to somehow tell play framework to scan submodules for entities. But how? – masterdany88 Sep 16 '14 at 07:42

I think Hibernate only scans for JPA Entities inside jar files, and not in classes/ folders for example, or it only scans in the jar with the persistence.xml, or something like that. Here's a solution with pure Hibernate on JavaSE, no Spring: https://stackoverflow.com/a/41845759/377320
