@Controller
public class DataController {
//一、接收和通过ModelMap传出参数,不需要视图解析器,测试时加了解析器,顾返回值不需后缀
//普通参数
@RequestMapping ( "/data1" )
public String data1( @RequestParam ( "uname" )String name,ModelMap mm){
//接收数据
//1.页面提交的表单域名和参数名需相同
//2.非要与提交的表单域名不一样的时候,如上加@RequestParam("uname"),但提交的表单域名名必须和uname相同
// System.out.println(name);
//传递数据到页面,添加ModelMap mm,类似request.setAttribute()
mm.addAttribute( "uname" , name);
return "data" ;
}
//对象参数
@RequestMapping ( "/data2" )
public String data2(User user,ModelMap mm){
//接收数据
//提交的表单域名需和对象里的属性名一致
// System.out.println(user);
//传递数据到页面,添加ModelMap mm,类似request.setAttribute()
mm.addAttribute( "user" , user);
return "data" ;
}
//二、接收和通过ModelAndView传出参数,需要配置视图解析器
@RequestMapping ( "/data3" )
public ModelAndView data3(HttpServletRequest req,HttpServletResponse resp){
ModelAndView mv = new ModelAndView();
User user = new User();
//接收数据
user.setName(req.getParameter( "name" ));
user.setPassword(req.getParameter( "password" ));
//传递数据
req.setAttribute( "uname" , user.getName());
req.setAttribute( "user" , user);
mv.setViewName( "data" );
return mv;
}
