import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.Errors;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;

@Controller
public class UserController{
    
    @GetMapping(value="/registerForm")
     public String registerForm(Model model){
        User user = new User();
        model.addAttribute("user",user);
        // 跳转到注册页面
        return "registerForm";
    }
     
    // 数据校验使用@Valid，后面跟着Errors对象保存校验信息
     @PostMapping(value="/login")
     public String login(
             @Valid @ModelAttribute  User user,
             Errors  errors,
             Model model) {
         System.out.println(user);
         if(errors.hasErrors()){
             return "registerForm";
         }
         model.addAttribute("user", user);
         return "success";
     }
