如何将枚举绑定到playframework表单？

public enum Color {
    RED("Red"),
    GREEN("Green"),
    BLUE("Blue");

    private String label;

    Color(String label) {
        this.label = label;
    }

    public String getLabel() {
        return label;
    }
}

import play.data.validation.Constraints;
import play.data.format.Formats;
import play.data.validation.Constraints.EnumMapping;

public class FormModel {
    @EnumMapping(enumClass = Color.class, message = "Invalid color")
    public Color color;

    // 其他表单字段...
}

@(form: Form[FormModel])

@import helper._

@select(
    form("color"),
    options(
        Color.values.map { value =>
            value.toString -> value.getLabel
        }
    ),
    '_default -> "-- Select color --"
)

import play.mvc.Controller;
import play.mvc.Result;
import play.data.Form;
import views.html.formTemplate;

public class FormController extends Controller {
    public Result submitForm() {
        Form<FormModel> form = Form.form(FormModel.class).bindFromRequest();
        if (form.hasErrors()) {
            return badRequest(formTemplate.render(form));
        } else {
            FormModel data = form.get();
            // 处理表单数据...
            return ok("Form submitted successfully");
        }
    }
}
