有关示例，请参见样本中的JPetstore，例如
SearchProductsController.java：
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { String keyword = request.getParameter("keyword"); if (keyword != null) { if (!StringUtils.hasLength(keyword)) { return new ModelAndView("Error", "message", "Please enter a keyword to search for, then press the search button."); } PagedListHolder productList = new PagedListHolder(this.petStore.searchProductList(keyword.toLowerCase())); productList.setPageSize(4); request.getSession().setAttribute("SearchProductsController_productList", productList); return new ModelAndView("SearchProducts", "productList", productList); } else { String page = request.getParameter("page"); PagedListHolder productList = (PagedListHolder) request.getSession().getAttribute("SearchProductsController_productList"); if (productList == null) { return new ModelAndView("Error", "message", "Your session has timed out. Please start over again."); } if ("next".equals(page)) { productList.nextPage(); } else if ("previous".equals(page)) { productList.previousPage(); } return new ModelAndView("SearchProducts", "productList", productList); }}
