                                           }

我希望模特herbenation是这样的：

@Entity
@Table(name = "Users")
public class Users extends Model {

@Id
public Long id;

@Required 
@Constraints.Pattern(value = "[0-9.+]+", message = "A valid phone number is required")
public String phoneNumber;

@Min(5)
@Required
public String firstName;


@Required
public String client ;

 @Min(100)
@Required
public int amount ;

}

我的ctroller方法如下：

   public static Result send( ) {


    Form<Users> formData_one = Form.form(Users.class).bindFromRequest();

   if (formData_one.hasErrors() )   {
        flash("error", " Please fill vaccant field ...");

          }
     else{

      }
       }

使用类似的东西

    @if(userForm.hasErrors) {
        <div class="alert alert-danger" role="alert">
        @for(error <- userForm.errors()) {
            <p>Error: @error._2.stream().findFirst().get().message()</p>
        }
        </div>
    }
