                 URL: https://issues.apache.org/jira/browse/WW-4366
             Project: Struts 2
          Issue Type: New Feature
          Components: Core Actions
            Reporter: samarjit samanta


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();

Inspiration can be taken from struts2-json-plugin#SMDMethod and (struts2-freeroute-plugin) [https://github.com/bastengao/struts2-freeroute]
