Answer 1

I have done some investigations of class scanning approaches, using answers from StackOverflow. So I gather all it together, using a Hibernate entities scanning as a test, in the one test project: hibernate-scanners-test.

Using fluent-hibernate

If you are looking for a quick scanning approach without additional dependencies, you can try fluent-hibernate library (you will not need to have other jars, except the library). Apart this, it has some useful features for Hibernate 5 and Hibernate 4, including entities scanning, a Hibernate 5 implicit naming strategy, a nested transformer and others.

Just download the library from the project page: fluent-hibernate and use EntityScanner:

For Hibernate 4 and Hibernate 5:

Configuration configuration = new Configuration();
EntityScanner.scanPackages("my.com.entities", "my.com.other.entities")
    .addTo(configuration);
SessionFactory sessionFactory = configuration.buildSessionFactory();

Using a new Hibernate 5 bootstrapping API:

List> classes = EntityScanner
        .scanPackages("my.com.entities", "my.com.other.entities").result();

MetadataSources metadataSources = new MetadataSources();
for (Class annotatedClass : classes) {
    metadataSources.addAnnotatedClass(annotatedClass);
}

SessionFactory sessionFactory = metadataSources.buildMetadata()
    .buildSessionFactory();
