Spring MVC command function

Hi,

I spent whole day being stucked at a bug that wasnt really a bug, but is actually born out of my weak understanding of Spring MVC.

Follow the link here: http://www.tutorialspoint.com/spring/spring_mvc_form_handling_example.htm
http://crunchify.com/simplest-spring-mvc-hello-world-example-tutorial-spring-model-view-controller-tips/


@RequestMapping
It is usually used to write the extended link address.
for eg, @RequestMapping("/welcome") would take care of all links in the server with localhost:8080/welcome/* to localhost:8080/welcome.html

However, in my situation where i am using a portal server,i actually use a
@RequestMapping("VIEW")
and extract the extended link address from

    protected HttpServletRequest getOriginalServletRequest(

   PortletRequest request) {

HttpServletRequest httpServletRequest = PortalUtil

.getHttpServletRequest(request);

HttpServletRequest originalServletRequest = PortalUtil

.getOriginalServletRequest(httpServletRequest);

return originalServletRequest;

    }

then, getParameter from the HttpServletRequest.

For eg, /non360?actionType=Amend
i will getParameter(actionType), which is Amend!


The next issue is the "command" object.
if you are using form, Spring MVC will only detect the "command" object, and ignore the rest.
