Subject [jira] [Commented] (CXF-6190) HttpServletRequest injection via Context in setter
Date Fri, 09 Jan 2015 08:18:34 GMT


Sergey Beryozkin commented on CXF-6190:

I do not understand this issue. It is the job of the runtime to ensure a context injected
into a field is a thread safe proxy and actually provide a thread-specific value. Why do you
need to do it ?

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.

> 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
