Overload Alfresco service

bch

Hi,

I want to overload an Alfresco service and more precisely NodeService. I want to add behavior so I must override methods like this :

    import org.alfresco.repo.version.NodeServiceImpl;
    import org.alfresco.service.cmr.repository.ChildAssociationRef;
    import org.alfresco.service.cmr.repository.InvalidNodeRefException;
    import org.alfresco.service.cmr.repository.NodeRef;
    import org.alfresco.service.namespace.QName;


    public class MyNodeService extends NodeServiceImpl {

       @Override
       public ChildAssociationRef createNode(NodeRef parentRef,
             QName assocTypeQName, QName assocQName, QName nodeTypeQName)
             throws InvalidNodeRefException {
          // Begin of my code
          …
          // End of my code
          return super.createNode(parentRef, assocTypeQName, assocQName, nodeTypeQName);
       }
    }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now, I must add Spring configuration but I don't know how and where. Have you an idea ?

Thanks

Benjamin

Hi Benjamin,

First question before to start the answer: Why don't you use a Spring interceptor or JavaBehaviourPolicy to add your feature ? To strictly answer your question, the nodeService bean spring configuration is defined in the WEB-INF/classes/alfresco/node-services-context.xml file and the NodeService configuration is in WEB-INF/classes/alfresco/public-services-context.xml file.

You should definately have a look at the OnCreateNodePolicy : this will be called after the node is created. Otherwise, you could add a Spring interceptor to the NodeService configuration. Have a look at the existing NodeService interceptors to see how it works.

Hi,

Thanks for your response. Here is my solution :

public class NodeService extends DbNodeServiceImpl {

   private Map<String,String> synchronizedAssocs = new HashMap<String, String>();

   @Override
   public AssociationRef createAssociation(NodeRef sourceRef,
         NodeRef targetRef, QName assocTypeQName)
         throws InvalidNodeRefException, AssociationExistsException {
      …
      return super.createAssociation(sourceRef, targetRef, assocTypeQName);
   }
   
   @Override
   public void removeAssociation(NodeRef sourceRef, NodeRef targetRef,
         QName assocTypeQName) throws InvalidNodeRefException {
      …
      super.removeAssociation(sourceRef, targetRef, assocTypeQName);
   }
   
   public Map<String, String> getSynchronizedAssocs() {
      return synchronizedAssocs;
   }

   public void setSynchronizedAssocs(Map<String, String> synchronizedAssocs) {
      this.synchronizedAssocs = synchronizedAssocs;
   }
}
