在CF9中使用隐式setter和getter时，我们处理什么验证？(What do we handle validation when using implicit setters and getters in CF9?)

使用隐式setter和getter时我们如何处理验证？ 我想当使用显式的getter和setter时，我们会做类似的事情：

public void function setFirstName() { if (! len(arguments.firstName)) { //throw some error/add an error to an error container } else { variables.firstName = arguments.firstName; } }

如果我们使用隐式getter和setter，我们可以在CFC本身中定义验证规则，例如：

/** * @validate string * @validateparams {minLength=2, maxLength=40} */ property String firstName;

我的问题是：

验证逻辑是在CFC本身，还是来自调用者？ 我们如何捕获错误并将其返回给用户以获得反馈？ 我可以考虑使用try / catch，但这应该在控制器还是模型中？

我是OOP的新手，我依靠CFWheels为我做这一切。 我想了解在没有框架的情况下如何处理此功能，或者如果我使用的是Hibernate。

How do we handle validation when using implicit setters and getters? I imagine when using explicit getters and setters, we would do something like:

public void function setFirstName() { if (! len(arguments.firstName)) { //throw some error/add an error to an error container } else { variables.firstName = arguments.firstName; } }

If we use implicit getters and setters, we can define validation rules within the CFC itself, such as:

/** * @validate string * @validateparams {minLength=2, maxLength=40} */ property String firstName;

My questions are:

Would validation logic be in the CFC itself, or from the caller? How do we trap errors and return them to the user for feedback? I can think of using try/catch, but should this be in the controller or the Model?

I'm a newbie to OOP and I've relied on CFWheels to do all of this for me. I'd like to learn how this functionality is handled in the absence of a framework, or if I were using Hibernate, for example.

当我在大学做Java时，验证通常在setter中完成。 但是，在web dev中工作了一段时间之后，我注意到它通常不是一个好主意，因为您通常希望构造一批错误消息并返回给用户。 因此，对象中的validateX()方法或返回错误集合的Service层上的validateX()方法将更合适。

话虽如此，除了ValidateThis之外，还有http://hyrule.riaforge.org/如果您正在运行CF9。

When I was in college doing Java, validation was usually done in setter. However, after working in web dev for a while, I noticed that it's generally not a good idea because you generally want to construct a batch of error messages and return to the user. Therefore, a validate() method in the object, or a validateX() method at the Service layer that returns a collection of errors would be more suitable.

Having said that, beside ValidateThis, there's also http://hyrule.riaforge.org/ if you are running CF9.
