ResourceInjector fails to inject into (Spring) proxies if resource to be in
injected is subclassed
--------------------------------------------------------------------------------------------------
Key: CXF-1645
URL: https://issues.apache.org/jira/browse/CXF-1645
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 2.0.6, 2.1, 2.1.1, 2.0.7
Reporter: Andreas Benneke
If the target is a proxy ResourceInjector tries to resolve an appropriate
setter method for the resource using
Method targetMethod = getTarget().getClass().getMethod(method.getName(), new
Class[]{resource.getClass()});
targetMethod.invoke(getTarget(), resource);
This fails if the resource has been subclassed because getMethod() (still) does
only exact matches (see
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4287725).
This is (for example) the reason why injecting the WebServiceContext into a
(Spring) proxy does not work: The real implementation WebServiceContextImpl is
always a subclass (see thread http://www.mail-archive.com/[EMAIL
PROTECTED]/msg03050.html)
As a solutions, the ResourceInjector might implement it's own matching
algorithm or e. g. use Spring's MethodInvoker instead which already contains
such an algorithm:
MethodInvoker targetInvoker = new MethodInvoker();
targetInvoker.setTargetObject(getTarget());
targetInvoker.setTargetMethod(method.getName());
targetInvoker.setArguments(new Object[]{resource});
targetInvoker.prepare();
targetInvoker.invoke();
