Java：循环类路径中的所有类 [英] Java : loop on all the classes in the classpath

问题描述

有没有办法迭代类路径中的所有类？

Is there a way to iterate over all the classes in the classpath ?

我想对某些实现某个接口的类进行一些反思性检查，但我想完全动态地完成它，而不需要检查哪些类，只需浏览类路径。

I want to make some reflective checks on some classes implementing a certain interface, but I want to do it completely dynamically, without any input on which classes to check, just browsing the classpath.

推荐答案

思考库有助于解决这个问题。正如其他人所说的那样，在所有类加载情况下都不是完全可能的，但如果您拥有的只是罐子和文件，那么这将是可靠的。

The Reflections library helps deal with this problem. As others have stated, it isn't fully possible in all class loading situations, but if all you have are jars and files, this will do it reliably.
