Junit + getResourceAsStream返回Null [英] Junit + getResourceAsStream Returning Null

问题描述

不确定这是怎么回事。我重读了getResourceAsStream并且它总是返回null。

Not sure how this is possible. I re-read up on getResourceAsStream and it's always returning null.

InputStream source = this.getClass().getResourceAsStream("test.xml");

Finder中的test.java旁边（使用OS X和Eclipse）是test.xml

Right next to test.java in the Finder (using OS X and Eclipse) is test.xml

我可以在TextWrangler中打开它并将其视为现有的数据。

I can open it in TextWrangler and view it as existing with data inside.

这是一个Junit测试，如果它有所不同。我去查看我们系统上现有的Junit测试，我使用的方式与工作示例完全相同（如文件所在位置和代码本身）。

This is a Junit test if it makes any difference. I went and looked at existing Junit tests on our system and I'm using it in the exactly same manner as a working example (as in where the file is located and the code itself).

可以防止我假设getClass（）返回正确的路径会有什么小的差别？

What small difference could there be preventing I assume getClass() from returning the right path?

谢谢！

推荐答案

getResourceAsStream（）正在使用CLASSPATH，因此它将从加载，无论你的类在哪里，而不是您的源文件。

getResourceAsStream() is using the CLASSPATH, and as such it will load from wherever your classes are, not your source files.

我怀疑您需要将XML复制到与.class文件相同的目录。

I suspect you need to copy your XML to the same directory as your .class file.
