“什么是”呢；自动将位置和资源属性注入控制器“；在JavaFX中？

在接口说明中，说明如下：

注：该接口已被自动注入 将位置和资源属性导入控制器。FXMLLoader将 现在自动调用任何适当注释的no arg initialize（） 由控制器定义的方法。建议注射 应尽可能采用这种方法

问题是：如何“适当注释”方法？我只找到一个注释--

@FXML

。还有其他的吗？

答案是：

在JavaFX2.1及更早版本中，需要控制器类 实现可初始化的接口，当内容 已完全加载关联的FXML文档的。在JavaFX中 2.2，这已不再必要。FXMLLoader类的实例只是在控制器上查找initialize（）方法并调用 如果有，请提供。请注意，与其他FXML回调方法类似 如事件处理程序，此方法必须用@FXML注释 注释（如果不是公共的）

建议开发人员在新的应用程序中使用此方法 发展。尚未弃用可初始化接口，但 可能在将来的版本中

编辑

经过更多研究，我现在可以提供一个SSCCE，演示如何将资源束注入带有注释的控制器。请注意，本SSCCE包含对答案的轻微修改

以下是SSCCE：
