------------------------------
Issue Type: Improvement (was: Bug)
> CDI plugin does not allow constructor injection
> -----------------------------------------------
>
> Key: WW-4215
> URL: https://issues.apache.org/jira/browse/WW-4215
> Project: Struts 2
> Issue Type: Improvement
> Components: Plugin - CDI
> Affects Versions: 2.3.15.2
> Reporter: gui
> Fix For: 2.3.17
>
>
> I'm converting some actions from spring injection to CDI injection.
> The beans have a non empty constructor that can be used by CDI (constructor
> is annotated with @Inject). I don't want to switch to field injection, since
> i like to use final fields for dependencies that don't change.
> However, cdi-plugin insists on having a no-arg constructor:
> {code}
> Caused by: Action class [com.mycompany.MyClass] does not have a public no-arg
> constructor - action - file:/struts.xml:22:106

> {code}
> After looking at the code, i created my own ObjectFactory that overrides the
> 'isNoArgConstructorRequired' method.
> {code}
> public class MyCdiObjectFactory extends CdiObjectFactory {
> @Override
> public boolean isNoArgConstructorRequired() {
> return false;
> }
> }
> {code}
> Using this objectfactory, all works as expected. It would be good to have
> this in the standard CidObjectFactory.
