@Controller
public class HelloWorldController {
@RequestMapping("/testForward")
public String testForward(Model model) {
User user=new User();
user.setUserName("baixue");
user.setPassWord("123");
model.addAttribute("user", user);
return "success";
}
@RequestMapping("/testRedirect")
public String testRedirect(Model model) {
User user=new User();
user.setUserName("baixue");
user.setPassWord("123");
model.addAttribute("user", user);
return "redirect:/success.jsp";
}
}
