I’m setting up a webapp and I’m trying to use Groovy instead of Java.

  • 0

I’m setting up a webapp and I’m trying to use Groovy instead of Java. I have the basic setup, the webapp starts. So far I have one Controller with the appropriate annotations. During startup the RequestMappings are mapped, but when I try to access the mapping, the webapp answers with a 404.

I’ve seen this post, but it didn’t solve my problem (neither using interfaces nor the PostProcessor).

Here’s the log from the application startup, I can’t see anything that looks strange:

This is the controller:

@Controller
@RequestMapping("/mapping")
class QueryController {

    @RequestMapping("/show")
    def show() {
        return "show";
    }
}

Am I missing something or doing something wrong? Help is greatly appriciated!

    What the heck, check this out, 2nd bullet down:

    Configuring and implementing Spring-style applications using Groovy 2:
    Groovy-based bean definitions; Groovy as the language of choice for an entire app

    from NEXT STOP: SPRING FRAMEWORK 4.0

    So you might be just tiny bit ahead of the time here :-). But you probably already knew that.
