第一种 : 通过ModelAndView
1 public class ControllerTest1 implements Controller {
2
3 public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
4 //返回一个模型视图对象
5 ModelAndView mv = new ModelAndView();
6 mv.addObject("msg","Tst");
7 mv.setViewName("test");
8 return mv;
9 }
10 }第二种 : 通过Model
1 @RequestMapping(path = "/u1")
2 public String setName(@RequestParam("userName") String name, Model model){
3 model.addAttribute("hello",name);
4
5 return "Login";
6 }
7 /**
8 * 接收前端用户传递的参数,判断参数的名字,假设名字直接在方法上,可以直接使用
9 * 假设传递的是一个对象User,匹配User对象中的字段,如果名字一致就能匹配,要是不一样则为null
10 *
11 * @param student
12 * @param model
13 * @return
14 */
15 @RequestMapping(path = "/u2")
16 public String setName2(Student student, Model model){
17 model.addAttribute("student",student);//student传到前端的数据
18 //返回映射地址
19 return "Login";
20 }
第三中:通过ModelMap
1 @RequestMapping(path = "/u3")
2 public String setName3(Student student,ModelMap modelMap){
3 //"student"传到前端的数据
4 modelMap.addAttribute("student",student);
5 //返回映射地址
6 return "Login";
7 }
