Mathieu Lalonde commented on CAMEL-4541:
----------------------------------------
After trying a simple fix, I take back my comment about preferring interface
methods to class methods since this breaks the component's annotation support.
I have a simple patch in the works that only prefers interface methods if the
bean's class is public. Since Camel would not have been able to "bean bind" a
non-public class anyways, this avoids breaking the annotation support on beans.
> Bean Binding should support interface methods for non-public classes

> As a user, I'd like to be able to use bean binding for non public classes.
> Bean binding is a strong selling point for Camel so it would be nice to have
> it work for non-public classes as well, provided that the target method is
> available via an implemented interface.
> eg.
> {code}
> // return private implementation of FooInterface
> FooInterface foo = Foos.newInstance();
> // works fine with plain java
> foo.doStuff("Hello");
> ...
> // This will throw an exception at runtime stating that the method can't be
> invoked (Illegal Access)
> from("direct:start").bean(foo, "doStuff").mock("direct:result");
> {code}
> The Bean component should at the very least prefer interface methods (which
> won't cause the above exception) to class methods when a matching method is
> available on both the class and its interfaces (it currently ignore interface
> methods).
> On a side note, its probably faster to look for interface methods first since
> there are usually less of them.
> I'll attach a unit test and patch soon.
