Bean Binding should support interface methods for non-public classes
--------------------------------------------------------------------
Key: CAMEL-4541
URL: https://issues.apache.org/jira/browse/CAMEL-4541
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Mathieu Lalonde
Assignee: Mathieu Lalonde
Priority: Minor
Fix For: Future
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.
