Welcome to the website of Davis Fiore

Here is how you usually read parameters in the controller:

	@RequestMapping(value = "/getproducts", method = RequestMethod.GET)
	public ModelAndView getProduct(@RequestParam("productId") int prodId, Model model,
		HttpServletRequest request)

In alternative, the parameters can be part of the path in the URL. In that case you would retrieve information as follows:

	@RequestMapping(value = "/product/{productId}", method = RequestMethod.GET)
	public @ResponseBody String getProduct(
			@PathVariable("productId") int productId)
