Utilizzo la libreria Google Guava per attività come l'ordinamento e il filtraggio di un java.util.List<T> in un'applicazione Java EE 7.java.lang.NoSuchMethodError: com.google.common.collect.FluentIterable.toList() Lcom/google/common/collect/ImmutableList;
Dato sotto un esempio di filtraggio di java.util.List<T> basato su un elenco di filtri in un bean CDI.
@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;
}
}
}
La classe nidificata può essere utilizzato per filtrare un java.util.List<T> dall'interno del fagiolo CDI come segue.
List<T> list = //Initialize the list here to be filtered.
//...
list = FluentIterable.from(list).filter((new Filtering(filters))).toList();
Dove filters è un java.util.Map<String, Object> in possesso di un elenco di filtri.
Questo stava funzionando benissimo in precedenza in un'applicazione Java EE con JSF Managed Fagioli (su GlassFish 4.0).
Ho migrato questa applicazione a GlassFish 4.1 con Fagioli gestiti CDI e si è verificata la seguente eccezione.

Sto usando Guava 17.0 su entrambe le applicazioni (ricontrollato).
Perché Guava non ama i fagioli CDI. Quale potrebbe essere la soluzione/soluzione alternativa?
UPDATE:
Ho provato a cambiare la versione da 18,0 ma nulla di nuovo è accaduto.
Si sta utilizzando la libreria locale all'interno di WAR o è distribuita nel server dell'applicazione? –
La libreria è locale in WAR. È memorizzato nella directory '/ WEB-INF/Lib' e aggiunto al classpath (in entrambe le applicazioni, una con bean gestiti JSF e l'altra con bean CDI). – Tiny
