Description

Struts2 action methods should accept arguments just like JAX-RS specs. Also certain method types should be allowed only like GET, PUT, POST, DELTE.
Inspiration might be taken from struts-json plugin @SMDMthod but that is not a real action method.

If there are multiple action methods in a Action class then it becomes less obvious which variables are used for a particular action method.

Ex.

    @ActionPath("/books/{id}")
    public String showAction(@PathParam("id") String id,
                                            @QueryParam("name") String name) {
		...
		return "success";
    }

Also flexible return types as defined in JAX-RS would be great or atleast

Result.json(myObject).includeActionErrors().includeActionMessages().done();
Result.string(myString).done();
Result.create("json").from(myObject).param("includeActionErrors,includeActionMessages").done();

The action method return type can be to denote builder like result. The closest in struts I can see is HttpHeaderResult. But this does not allow arbritrary string result and let the end user create the string as json or plain text.

   @Action
   public Result showAction(...){}
