Unfortunately no, java.net.URL is not a natively supported property
type. However it's pretty easy to make Objectify automatically
convert it to String. I just added this to Objectify4 if you're
comfortable building from trunk (and upgrading - the API has changed
quite significantly).
In Objectify3, add this converter to your ObjectifyFactory:
/**
* Call factory.getConversions().add(new URLConverter());
*/
public class URLConverter implements Converter
{
@Override
public Object forDatastore(Object value, ConverterSaveContext ctx)
{
if (value instanceof URL)
return ((URL) value).toString()();
else
return null;
}
@Override
public Object forPojo(Object value, Class<?> fieldType,
ConverterLoadContext ctx, Object onPojo)
{
if (value instanceof String &&
URL.class.isAssignableFrom(fieldType))
return new URL((String)value); // you'll need
to try/catch the MalformedURLException here
else
return null;
}
}
