Question

我在http://www.playframework.org/documentation/2.0.4/JavaTodoList上做的例子但我有形式的问题。如果您查看“任务表单”部分，您会看到我被要求添加 static Form taskForm = form（Task.class）; 到应用程序控制器。

我得到的问题是“方法表单（类）未定义类型Application”

我正在运行play-2.1-RC1而不是play-2.0.4（play-2.0.4是示例中谈到的那个）

这是我得到的编译错误

Answer 1

更改行：

form(Task.class);

有：

Form.form(Task.class);

当然，您必须添加：

import views.html.*;
