SpringMVC Controller Method Doesn't Bring in Model

Question

I noticed that when a Form Submit happens, my handler method that captures a @Model object as a parameter does have a valid Model available to me, e.g.

public ModelAndView save(final HttpServletRequest request, 
             @ModelAttribute(MODEL_NAME) MyModel model,
             BindingResult bindingResult)

But when I have a handler method corresponding to a URL redirect from a simple <a href=".."> button/link, e.g.

<a href="myController.do&function=add">

leading to

@RequestMapping(params = "function=add")
public ModelAndView add(final HttpServletRequest request, 
          @ModelAttribute(MODEL_NAME) MyModel model) throws Exception

in that case, the model object is NULL. The model wasn't carried through the request and made available to me in the handler method.

Is there a way to reexpose the model? I do have the same param in both methods, but in the 2nd one the "model" object is NULL.

If you want to use GET request with you will need to add the model to the URL. Or you can use POST with a form instead.

But the model can't be serialized into a string? How would it be made into a string param? – gene b. Jan 23 '17 at 14:18
And I *really* don't want to use Session attributes, that's horrible – gene b. Jan 23 '17 at 14:19
