本文探讨了在Java中使用getResourceAsStream方法加载资源时遇到返回null的情况，并提供了两种解决方案。一种是通过Lifepaths.class.getClass().getResourceAsStream(...)，另一种是通过Lifepaths.class.getResourceAsStream(...)。此外，还强调了在调用getResourceAsStream(name)时，name参数必须以/开头的重要性。

Lifepaths.class.getClass().getResourceAsStream(...) loads resources using system class loader, it obviously fails because it does not see your JARs

Lifepaths.class.getResourceAsStream(...) loads resources using the same class loader that loaded Lifepaths class and it should have access to resources in your JARs

Just to add on, When invoking getResourceAsStream(name), the name must start with "/". I am not sure whether this is necessary, but I have problem without it. – David Nov 15 '15 at 7:54

I have been screwing with this since 8am this/yesterday morning. Saved me. I did also need a leading slash to make it work. – kyle Jan 28 at 6:05
