如何阻止使用google guava库中的beta类？

Question

We have been using Google collections in the production for several months. We would like to start using guava for additional functions. However, I'm afraid to bring guava into our product stack b/c some developers may start to use 'beta' classes.

We have various unit-tests in our code but at this point, I prefer not to include 'beta' class b/c it is subject to change in the future.

Is there any easy way to do detect if the project includes any 'beta' guava classes?

Answer 1

Overstock.com最近发布了一个Findbugs插件，用于标记@Beta类，方法或字段的使用。

Answer 2

在单元测试中，在使用任何beta类（或任何不受欢迎的类）时设置一个方面来记录和/或失败。

Answer 3

Apparently Google Guava has an @Beta annotation which indicates which classes or methods you don't want to use.

Unfortunalty this annotation is @Retention(value=CLASS) which I've never used but since it's supposed to be kept in .class files it might mean that it will still be availiable to Class.getDeclaredAnnotations() . If it's not you will have to use CGLIB or similar bytecode level library to find it.

Given that you might want to instrument your CI application or add a checking classloader to your app to detect usage of beta API

If you're using eclipse, access rules are one option. You'd get a compile-time error whenever you are importing or otherwise using a restricted class.

Answer 5

I was thinking you could probably use reflection for that if you had a list of beta classes, which you can using Gili's link. Then it gets pretty easy - just see this answer:

Can you find all classes in a package using reflection?

I'd probably just put that in a unit test and have the unit test fail if it sees a class you don't like.

Answer 6

这是一个Guava的Beta类列表。在使用guava类之前，你必须告诉其他开发人员检查这个链接。
