----------------------------------
The issue is that injection via setter is not working and throws that
IllegalArgumentException. You are right that it happens during runtime, this is
what happens:
{code:java}
public static void injectThroughMethod(Object requestObject,
Method method,
Object parameterValue, // !!!
This is ThreadLocalHttpServletRequest
Message inMessage) {
try {
Method methodToInvoke = checkProxy(method, requestObject);
methodToInvoke.invoke(requestObject, new Object[]{parameterValue});
// !!! This fails as you cannot call setRequest(ThreadLocalHttpServletRequest)
} catch (IllegalAccessException ex) {
reportServerError("METHOD_ACCESS_FAILURE", method.getName());
} catch (InvocationTargetException ex) {
Response r = JAXRSUtils.convertFaultToResponse(ex.getCause(),
inMessage);
if (r != null) {
inMessage.getExchange().put(Response.class, r);
throw new WebApplicationException();
}
reportServerError("METHOD_ACCESS_FAILURE", method.getName());
} catch (Exception ex) {
reportServerError("METHOD_INJECTION_FAILURE", method.getName());
}
}
{code}
> HttpServletRequest injection via Context in setter

> Key: CXF-6190
> URL: https://issues.apache.org/jira/browse/CXF-6190
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.0.3
> Reporter: Zdeněk Obst
>
> I'm trying to inject HttpServletRequest to my JAX-RS resource via @Context
> annotation. It works fine if I inject it via method parameter. But I don't
> want to "mess" my interfaces with that so I'd like to inject it via setter.
> I use this simple method (I'm using Kotlin but I the issue should be the same
> for Java):
> {code:java}
> var req : HttpServletRequest? = null
> Context
> fun setRequest(req : HttpServletRequest) {
> this.req = req
> }
> {code}
> The thing is, that the setter is called via reflection in
> org.apache.cxf.jaxrs.utils.InjectionUtils in method injectThroughMethod. The
> method name is correct but as parameter value is instance of
> ThreadLocalHttpServletRequest which clearly is not HttpServletRequest (it is
> not inherited class) so this gets thrown:
> java.lang.IllegalArgumentException: object is not an instance of declaring
> class
