hop of those help? You can pass session as an attribute of controller's method and then use it directly without request.getSession(), however it isn't a big improvement and there are no annotations :)
code :
public String handleRequest(HttpSession session) {
    session.setAttribute("key", "value");
}

This might help you When I want a model in Session scope in Spring 3, I use the foll. annotation in a Controller:- , @SessionAttribute works as follows:
code :
@SessionAttribute("myModel")
@Controller
public class MyController {
    @RequestMapping(...)
    public String displayForm(@RequestParam("id") long id, ModelMap model) {
        MyModel m = findById(id);
        model.put("myModel", m); // Initialized
        return ...;
    }

    @RequestMapping(...)    
    public String submitForm(@ModelAttribute("myModel") @Valid MyModel m,
        BindingResult errors, SessionStatus status) {
        if (errors.hasErrors()) {
            // Will render a view with updated MyModel
            return ...;
        } else {
            status.setComplete(); // MyModel is removed from the session
            save(m);
            return ...;
        }

    }
}

should help you out I'm new to Spring MVC and I'm learning about SessionAttribute. , You can always do it the JEE way:
code :
@RequestMapping(method = { RequestMethod.GET, RequestMethod.POST })
public String home(HttpSession session) {
    session.setAttribute("myparam", "myvalue");
    return "home";
}

will help you You could make @RequestParam as not required. This would allow your request to succeed, but query would then be null.
code :
@ModelAttribute("persons")
public List<Person> getPersons(@RequestParam(value="query" , required=false) String query) {
  List<Person> personList = personService.SearchByName(query);
  return personList;
}
