<!--默认的内置视图解析器-->
<bean id="viewResolver" class="org.springframework.WEB.servlet.view.InternalResourceViewResolver">
    <!--设置前缀-->
    <property name="prefix" value="/WEB-INF/templates"/>
    <!--设置后缀-->

//使用servlet传递数据
@RequestMapping("/testServlet")
public String testRequestByServletapi(HttpServletRequest request){
    request.setAttribute("test","hello,servlet");
    return "success";
}

 @RequestMapping("/testModelAndView")
    public ModelAndView testModelAndView(){
        //创建ModelAndView对象
        ModelAndView mav = new ModelAndView();
        //处理模型数据，即向请求域request共享数据
        mav.addObject("test","Hello ModelAndView");
        //设置视图名称
        mav.setViewName("success");
        return mav;
    }

@RequestMapping("/testModel")
public String testModel(Model model){
     model.addAttribute("test","Hello Model");
     return "success";
 }

 @RequestMapping("/testMap")
 public String testMap(Map<String,Object> map){
     map.put("test","Hello Map");
     return "success";
 }

 @RequestMapping("/testModelMap")
 public String testModelMap(ModelMap modelMap){
     modelMap.addAttribute("test","hello modelmap");
     return "success";
 }

//向session域共享数据
@RequestMapping("/testSession")
 public String testSession(HttpSession httpSession){
     httpSession.setAttribute("testSessionScope","hello session");
     return "success";
 }

 //向application域共享数据
 @RequestMapping("/testApplication")
 public String testApplication(HttpSession session){
     ServletContext servletContext = session.getServletContext();
     servletContext.setAttribute("testApplicationScope","hello application");
     return "success";
