play太好用了，表单用起来也是让我们的开发速度搜搜的。闲话少说，上demo。

简单的demo

1、在routes添加访问表单的路径

# Home form add by meGET     /form                           controllers.Application.form()

通过http://localhost:9000/form访问到我们的表单模板

2.添加application中处理form跳转的方法

public static Result form() {        return ok(form.render("winter you are bang"));    }

跳转到form.scala.html页面

3、添加form.scala.html页面

@(dong:String)<!DOCTYPE html><html>    <head>        <title>@dong</title>        <link rel="stylesheet" media="screen" href="@routes.Assets.at("stylesheets/main.css")">        <link rel="shortcut icon" type="image/png" href="@routes.Assets.at("images/favicon.png")">        <script src="@routes.Assets.at("javascripts/jquery-1.9.0.min.js")" type="text/javascript"></script>    </head>    <body>        <form method="POST" action="/postForm">      <label>Email</label>      <input type="email" name="email">      <label>Password</label>      <input type="password" name="password">      <label>Comment</label>      <input type="text" name="comment">      <input type="submit">    </form>    </body></html>

4.添加routes处理表单的

# Home form add by me  postFormModel postFormPOST     /postForm                           controllers.Application.postFormModel()

5、application中添加方法处理表格提交

public static Result postFormModel() {        String [] params = {};        DynamicForm bindFromRequest = Form.form().bindFromRequest(params);        String email = bindFromRequest.get("email");        String password = bindFromRequest.get("password");        String comment = bindFromRequest.get("comment");        System.out.println("email--"+email);        System.out.println("password--"+password);        System.out.println("comment--"+comment);        System.out.println(bindFromRequest);        return ok(dong.render("dong ge wei wu ","winter"));    }

大神的处理：

public static Result postFormModel() {        Form<User> userForm = Form.form(User.class);        User user = userForm.bindFromRequest().get();        return ok(dong.render(user.email ,user.password));       }

大神世界：

form.scala.html可以有程序生成：通过http://localhost:9000/form访问到我们的表单模板

@(userForm: Form[model.User])<!DOCTYPE html><html>  <body>      @helper.form(action = routes.Application.postFormModel()) {      @helper.inputText(userForm("email"))      @helper.inputPassword(userForm("password"))      @helper.inputText(userForm("comment"))      <input type="submit">    }  </body></html>

model的user

package model;import play.data.validation.Constraints.Email;import play.data.validation.Constraints.Required;public class User {    @Email    public String email;    @Required    public String password;    public String comment;}
