I need to map Entities that are not listed at hibernate.cfg.xml, those classes are loaded dynamically
from an arbitraty folder. I'm trying to register a ClassLoaderService to change de loading behavior, the
following code runs fine if the classes are defined at compile time and exist in the classpath, but if
I try to map a dinamically loaded class I get ClassNotFoundException.
Code:
URL file = ConsultaBase.class.getProtectionDomain().getCodeSource().getLocation().toURI().resolve("implementacao/").resolve("hibernate.cfg.xml").toURL();
Configuration configuration = new Configuration()
.addAnnotatedClass(Registro.class).configure(file);
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder (
new BootstrapServiceRegistryImpl(
new ClassLoaderServicePirilampo(Registro.class.getClassLoader()),
new LinkedHashSet<Integrator>()
)
)
.applySettings(configuration.getProperties())
.addService(ClassLoaderService.class, new ClassLoaderServicePirilampo())
.build();
//this line throws ClassNotFoundException
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
I extended the ClassLoaderServiceImpl in order to log the requested classes, and noticed that running from JUnit, from the project where the classes are defined, I get the class loading log from the Service, but the Service never receive
the request for the same class if I addAnnotatedClass that was loaded dinamically (from GroovyClassLoader).
The last line throws de folowing error:
Code:
17:06:49 ERROR [AssertionFailure] HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): java.lang.ClassNotFoundException: implementacao.Registro
