I think I misinterpreted what Kevin said.
I agree that using annotations is preferable, although name based matching can be also left in place, in case annotations are not present, as I mentioned, for imported classes.
That doesn't actually address the issue. If you import class X and it has method getFoo(xxx), it doesn't work.
An adapter is definitely preferrable for that.

True, and of course we do that for our own classes. But in case you end up using some other class that comes from standard Java or some library, you can't annotate that. Perhaps using an adapter in some way might be the only way then.
Besides, I actually don't see annotations being taken into account in BeanJsonConverter code. It just grabs all methods that start with "get" when converting object to json. Actually, I just noticed that in the Person class from org.apache.shindig.social.opensocial.model, getGender is not annotated, neither is getUtcOffset, yet both of them are converted to json.

I think it would make more sense to use annotations on the beans instead of doing name based matching. That way you're always explicit in what you export and don't have problems like this.

Hi all,
I¹ve had problems using BeanJsonConverter on objects that contain getters that have 1 or more arguments. Since convertMethodsToJson() expects not to see any arguments on getters, invoke() will crash on getters that have some.
Do you think we should adjust getMatchingMethods() to filter out getters that require parameters? Or just skip those getters in convertMethodsToJson(). I think it is reasonable to assume we don¹t need those for conversion purposes.
Thanks,
Aleksey
