The idea to lookup beans by presence of methods seems weird to me 

Yet that's essentially what happens in Jakarta REST. Leaving path combining out, you essentially get a request for path "/foo/bar", so you look up a bean declaring to handle "/foo/bar".

Now declaring this can be done in two ways; in pseudo code:

1.

@Path("/foo/bar")

class Resource{

}

2.

class Resource{ 

   

    @Path("/foo/bar")

    void myMethod() {}

}

So working on a prototype implementation for this, I just wondered; why can we query beans based on qualifiers at the class-level only. Why don't we include qualifiers on methods as well?

Note that more powerful bean queries are also related to my other proposal for being able to provide a synthetic injection point for a bean lookup.

Kind regards,
