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>
  

Model传递

• 编写controller

  @Controller
  @RequestMapping("/account")
  public class AccountController {@RequestMapping(value = "/findAccount10")public String findAccount10(Model model) {model.addAttribute("msg", "欢迎你 springmvc");return "success";}
  }
  

• 在index.jsp里面定义超链接

  <a href="/account/findAccount10">Model参数传递</a>
  

ServletAPI传递

• 编写controller

  @Controller
  @RequestMapping("/account")
  public class AccountController {@RequestMapping("/findAccount11")public String findAccount11(HttpServletRequest request, HttpServletResponse response){request.setAttribute("msg","欢迎你 springmvc");return "success";}
  }
  

• 在index.jsp里面定义超链接

  <a href="/account/findAccount11">ServletAPI传递</a>
