Custom Node Service

lamba · ‎4 Jun 2010

Bonjour,

Quelqu'un SVP, pour m'expliquer comment créer un Node Service personnalisé.

En fait, ce que je veux modifier c'est la méthode public List<ChildAssociationRef> getChildAssocs(NodeRef nodeRef) qui permet de charger les fils d'un espace lors de sa consultation, n'est ce pas?

Et pour se faire j'ai créé la classe ci-dessous:


public class CustomNodeServiceImpl implements NodeService {
        
        private ServiceRegistry services;
   private NodeService nodeService;
   
   //Constructor
   public CustomNodeServiceImpl(ServiceRegistry services, NodeService nodeService) {
      super();
      this.services = services;
      this.nodeService = nodeService;
   }
   
   //MAJ dynamique du contenu 
   public List<ChildAssociationRef> getChildAssocs(NodeRef nodeRef) throws InvalidNodeRefException{
      …
                //Mon code personnalisé
                …            
   }

   //Getters and Setters
   public void setServices(ServiceRegistry services) {
      this.services = services;
   }
   
   public void setNodeService(NodeService nodeService){
      this.nodeService = nodeService;
       }

      private NodeService getNodeService(){
       if (nodeService == null){
            nodeService = Repository.getServiceRegistry(FacesContext.getCurrentInstance()).getNodeService();
        }
        return nodeService;
    }

//Unimplemented Methods

   @Override
   public void addAspect(NodeRef nodeRef, QName aspectTypeQName,
         Map<QName, Serializable> aspectProperties)
         throws InvalidNodeRefException, InvalidAspectException {
      // TODO Auto-generated method stub
      
   }

   @Override
   public ChildAssociationRef addChild(NodeRef parentRef, NodeRef childRef,

   }

   @Override

Bonjour,

c'est la méthode public List<ChildAssociationRef> getChildAssocs(NodeRef nodeRef) qui permet de charger les fils d'un espace lors de sa consultation, n'est ce pas?

Ca dépend… Consultation par quel biais : Web Client, Share, FTP, CIFS ?

De toutes manières c'un peu violent de vouloir redéfinir le NodeService juste pour modifier une méthode. Et la modification de cette méthode peut amener pas mal de bugs…
Je conseillerais de plutôt faire la modification un cran au-dessus, dans du code plus "fonctionnel", ou éventuellement dans le FileFolderService (méthodes list ou listFiles).

Merci Philippe

Tu as raison …

ops:

Donc, je vais repartir de ta proposition et personnaliser la méthode listFiles(NodeRef contextNodeRef) de la classe FileFolderService et les méthodes en relation (listSimple(NodeRef contextNodeRef, boolean folders, boolean files), toFileInfo(List<NodeRef> nodeRefs), FileInfo toFileInfo(NodeRef nodeRef, boolean addTranslations) …)

Pour la consultation, je m'intéresse dans un premier temps par le Web Client puis Share.

Merci.
