jjaram / chameleon

Is a java framework that helps the copy objects that have the same attributes types, without the necessity to create heavy factories and deal with the creation of the subrelations objects.

chameleon's Issues

Create jpa adapter

Actually we have the hibernate logic linked in the principal project, we want to separate the logic to prevent create a big jar

public static ChameleonProxyAdapter getInstance(Field field, String fieldName, Object data) throws InstantiationException, IllegalAccessException, NoSuchFieldException {
     ChameleonProxyAdapter proxy = new DefaultProxyChameleon(field, fieldName, data);
     if (proxy.getValue() != null) {
          if (proxy.getValue() instanceof HibernateProxy ) {
               proxy = new HibernateProxyChameleon(proxy.getValue(), field);
          } else if (proxy.getValue() instanceof PersistentSet) {
               proxy = new PersistentSetProxy(proxy.getValue(), field);
          }
     }
     return proxy;
}

Maybe we want think in create and herency of classes using Adapter Pattern

Moved logic in ChameleonQueryManagerHelper

Actually ChameleonQueryManagerHelper has static method that needs to be moved to a new class.

Create proxy for repository

Actually when we want to create queries using @query we need to create a new class and add the annotation but in the body we need to return a null value as the example:

@Component
public class PlaceDTORepository {

    @Query("SELECT V.referenceId, V.name, P.referenceId, P.prefix, P.suffix, P.width, P.height FROM Place V JOIN Photos P")
    public Set<PlaceDTO> fetchNearPlacesByLocationName(Set<Place> source) {return null;}
}

So in the new solution we want to create queries in a interface, like SpringData.

Create reader of properties

We need to create a reader properties, because currently with the creation of the ticket #2 we set the ProxyVendorAdapter by default using hibernate.

public class ChameleonVendorAdapterStrategy {

    public static VendorProxyAdapter getInstance(Field field, String fieldName, Object data) throws InstantiationException, IllegalAccessException, NoSuchFieldException {
        VendorProxyAdapter proxy = new DefaultProxyChameleon(field, fieldName, data);
        if (proxy.getValue() != null) {
            try {
                Class<?> clazz = Class.forName("com.jjm.chameleon.support.proxy.jpa.HibernateVendorProxyAdapter");
                Constructor<?> constructor = clazz.getConstructor(Object.class, Field.class);
                proxy = (VendorProxyAdapter) constructor.newInstance(new Object[] { proxy.getValue(), field });
            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            } catch (NoSuchMethodException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                e.printStackTrace();
            }
        }
        return proxy;
    }
}
