Я использую библиотеку Google Guava для таких задач, как сортировка и фильтрация java.util.List<T> в приложении Java EE 7.
Ниже приведен пример фильтрации java.util.List<T> на основе списка фильтров в CDI bean.
@Named
@ViewScoped
public class Bean extends LazyDataModel<T> implements Serializable {
private static final long serialVersionUID = 1L;
private final class Filtering implements Predicate<T> {
private final Map<String, Object> filters;
public Filtering(Map<String, Object> filters) {
this.filters = filters;
}
@Override
public boolean apply(T p) {
if (p == null) {
return false;
}
Integer id = (Integer) filters.get("id");
if (id != null && !p.getId().equals(id)) {
return false;
}
BigDecimal size = (BigDecimal) filters.get("size");
if (size != null && ((p.getSize().compareTo(size) < 0))) {
return false;
}
return true;
}
}
}
Вложенный класс можно использовать для фильтрации java.util.List<T> внутри CDI bean следующим образом.
List<T> list = //Initialize the list here to be filtered.
//...
list = FluentIterable.from(list).filter((new Filtering(filters))).toList();
Где filters является java.util.Map<String, Object>, содержащим список фильтров.
Это отлично работало в приложении Java EE с JSF Managed Beans (на GlassFish 4.0).
Я перенес это приложение в GlassFish 4.1 с управляемым CDI Beans, и произошло следующее исключение.

Я использую Guava 17.0 для обоих приложений (дважды проверял его).
Почему Гуава не нравится CDI beans. Каким может быть решение/обход?
ОБНОВЛЕНИЕ:
Я попытался изменить версию до 18.0, но ничего нового не произошло.
