Spring MVC之——数据传递
1.ModelAndView传递
-
编写controller
@Controller @RequestMapping("/account") public class AccountController { //也可以不创建ModelAndView，直接在参数中指定 @RequestMapping(value = "/findAccount9") public ModelAndView findAccount9(ModelAndView mv) { mv.addObject("msg", "欢迎你 springmvc"); mv.setViewName("success"); return mv; } } -
在index.jsp里面定义超链接
<a href="/account/findAccount9">ModelAndView参数传递</a>
