　　　　　　　　　　　　　　　　　　　　　　　　　　ModelAndView的部分回顾

//@RestController
@Controller
//@SessionAttributes("user")
//把modelandview中user attribute对象 拷贝了一份到session的共享控制当中。
public class Test01Controller {
//    path 和value一样 但是produces = "text/html;charset=utf-8"不能变
    @RequestMapping(path = "/mv/{path}.do",produces = "text/html;charset=utf-8")
    public ModelAndView test(@PathVariable("path") String path){
        System.out.println(path);
        ModelAndView mv = new ModelAndView();
        Map  map = new HashMap();
        map.put("username","admin");
        map.put("password","123456");
        //一次性添加多个attribute对象
        mv.addAllObjects(map);
        //attribute对象 request
        mv.addObject("user","username");
        //你要跳转到那里  服务器跳转
        //也可客户端跳转但是值就不能传递了
        mv.setViewName("/success.jsp");
        return mv;
