add URL parameter in render method for liferay portlet

I'm developing an MVC portlet using spring MVC. I want to add URL parameter to the URL of the opened page from the corresponding render mapping method. For example for this controller class:

@Controller(value = "SpringMvcController")
@RequestMapping(value = "VIEW")
public class SpringMvcController {
    @RenderMapping
    public ModelAndView handleRenderRequest(RenderRequest request,RenderResponse response,Model model) {

        ModelAndView modelAndView= new ModelAndView("view");
        /*What should I add here*/
        return modelAndView;

    }
}

I want to add some code in order when the view.jsp page is opened a parameter is added to the url like that ?param=value

Is that possible?

Just add your parameters to your ModelAndView Object so you can access them in your .jsp file:

Controller.java:

@Controller(value = "SpringMvcController")
@RequestMapping(value = "VIEW")
public class SpringMvcController {
    @RenderMapping
    public ModelAndView handleRenderRequest(RenderRequest request,RenderResponse response,Model model) {

        ModelAndView modelAndView= new ModelAndView("view");
        modelAndView.addObject("objectName", object);
        return modelAndView;
    }
}

SomeJspFile.jsp:

...
<p>${objectName}</p>
...

If you create your own object and you create all Getters and Setter you even can access attributes of this object like this:

SomeJspFile.jsp:

...
<p>${objectName.attributeName}</p>
...

You can get this parameter from request, like that:

@RenderMapping
public ModelAndView handleRenderRequest(RenderRequest renderRequest, RenderResponse response, Model model) {
    HttpServletRequest request = PortalUtil.getOriginalServletRequest(PortalUtil
            .getHttpServletRequest(renderRequest));
    String param = ParamUtil.getString(request, "param");

    ...

}
