I've been working on an app that uses struts lately and was following
the PetStore example. I managed to figure out how to get it to work but
I'm not sure if there is a better way or not.
What I wound up doing was creating a base ServletService with extends
the Servlet and ServiceComposite interfaces. Then, for the actual
service that gets registered I extended that ServletService and used the
servlet that I wanted as the mixin.
I did the same thing for filters, creating a FilterService that extends
Filter and ServiceComposite. Next I created a few convenience methods
so I can more naturally add Filters like so
// Add the struts filter
addFilters(
filter("*.action").through(FilterDispatcherService.class).on(REQUEST,
FORWARD).withInitParams(
immutableMap("actionPackages",
"com.compunetconsulting.trinket.web.struts.actions")
)
).to(module);
It works out pretty darn well. And I even, finally, got an
ObjectFactory implemented that allows struts to use Qi4j composites as
actions like so
@Mixins({ActionSupport.class})
public interface Home extends Action, Composite {
}
It wasn't easy, but I did it. If anyone is interested I can see about
cleaning up the code a bit and contributing it.
