Example 1 with ClassPathScanner

use of de.invesdwin.util.classpath.ClassPathScanner in project invesdwin-context-persistence by subes.

the class JpaRepositoryScanContextLocation method scanForJpaRepositories.

private Map<Class<?>, Set<Class<?>>> scanForJpaRepositories(final String basePackage) {
    final Map<Class<?>, Set<Class<?>>> jpaRepositories = new HashMap<Class<?>, Set<Class<?>>>();
    final ClassPathScanner scanner = new ClassPathScanner().withInterfacesOnly();
    scanner.addIncludeFilter(new AssignableTypeFilter(JpaRepository.class));
    final Set<BeanDefinition> candidateComponents = scanner.findCandidateComponents(basePackage);
    for (final BeanDefinition bd : candidateComponents) {
        final String beanClassName = bd.getBeanClassName();
        final Class<?> repositoryClass = Reflections.classForName(beanClassName);
        if (!IDao.class.isAssignableFrom(repositoryClass)) {
            final Class<?>[] typeArguments = Reflections.resolveTypeArguments(repositoryClass, JpaRepository.class);
            Assertions.assertThat(typeArguments.length).isEqualTo(2);
            final Class<?> entity = typeArguments[0];
            Set<Class<?>> set = jpaRepositories.get(entity);
            if (set == null) {
                set = new HashSet<Class<?>>();
                jpaRepositories.put(entity, set);
            }
            Assertions.assertThat(set.add(repositoryClass)).isTrue();
        }
    }
    return jpaRepositories;
}

Example 2 with ClassPathScanner

use of de.invesdwin.util.classpath.ClassPathScanner in project invesdwin-context-persistence by subes.

the class PersistenceUnitAnnotationUtil method scanForEntities.

    final ClassPathScanner scanner = new ClassPathScanner();

         * either @Entity, @Embeddable or @MappedSuperclass.
         *

            persistenceUnitName = PersistenceProperties.DEFAULT_PERSISTENCE_UNIT_NAME;
        }
        Set<Class<?>> set = entities.get(persistenceUnitName);
