ColdFusion 2018 Bean-DAO-Manager OOP 逻辑错误

Question

我正在尝试通过重新创建经过验证的 Bean-DAO-Manager 设置来了解 ColdFusion 中的 OOP。在示例中，我仅使用 Create，但读取、更新和删除也存在问题。 我认为我在传递论点时犯了一些错误。 在 index.cfc 中，我从包含 API 的 testBeanDaoManager.cfc 创建一个对象。在这里，创建了应该保存属性的 bean。从那里调用管理器，该管理器调用文件 testDAO.cfc 中的 db-query。

错误表明找不到 bean 的方法 getName()（更多详细信息在帖子末尾）。

非常感谢任何帮助。

（评论太长）

你在打电话

var bean = gettestBean(arguments.ID);

它指向gettestBean 的/api/testBeanDaoManager.cfc。这个可以

var nameManager = createObject('component', 'logic.manager.testManager');
var nameBean = nameManager.getName(arguments.ID);
return nameBean;

但是logic.manager.testManager 没有任何getName 功能。即使它有一个，您也必须返回一个实例（bean），这对于称为 getName 的方法有点误导。
