【web開發】基於註解spring的多方法請求的一種controller實現

僅作學習筆記，具體代碼如下：

@Controller@RequestMapping(value="mainPage")  // 類對應的請求urlpublic class MainPageController extends AbstractController{                                                                                                                                                     // 實現Controller介面中的handleRequestInternal方法, 跳轉時預設情況下會被調用    public ModelAndView handleRequestInternal(HttpServletRequest req,            HttpServletResponse res) throws Exception {        HashMap<String, Object> model = new HashMap<String, Object>();// TODO: add the model data                return new ModelAndView("mainPage",model);    // 'mainpage' is the view name       }    // 在請求url中帶參數method=changePageNo時，該函數被調用    @RequestMapping(params = "method=changePageNo")    public ModelAndView changePageNo(@RequestParam("pageNo")String pageNo,      HttpSession session) throws Exception {   session.setAttribute("pageNo", pageNo);     HashMap<String, Object> model = new HashMap<String, Object>();// TODO: add the model data    return new ModelAndView("mainPage",model);     }           // ...可實現更多的對應不同參數url的控制方法}
