在Eclipse中可见但在jar中不可见的资源
[英]resources visible in eclipse but not in jar
问题描述
In a java project I have been given, at one point an external file is referenced. 
在一个Java项目中，我曾经引用过一个外部文件。 This file is held in a folder named resources . 该文件保存在名为resources的文件夹中。 In the code, the call is: 在代码中，调用为：
DHKeyReader d = new DHKeyReader("resources/filename")
When run in Eclipse (3.7.2) this executes without failure. 在Eclipse（3.7.2）中运行时，此操作将成功执行。 However, when exported to a jar, this fails with an IOException. 但是，当导出到jar时，此操作将失败，并出现IOException。
I am hesitant to modify the code, as it was given to me under the pretense that it worked and I was to familiarize myself with it so it could be altered. 我很犹豫要修改代码，因为它是在假装有效的情况下提供给我的，我想让自己熟悉它以便可以对其进行更改。 However, there still could be errors. 但是，仍然可能有错误。
My question is this: how do I make a folder (held on the root of the .jar) visible within the jar like it is when running in Eclipse? 我的问题是：如何像在Eclipse中运行时一样，在jar中使文件夹（保存在.jar的根目录中）可见？

This is because at runtime the classloader is not able to find the resource. 这是因为在运行时，类加载器无法找到资源。 Its always better to use : YourClass.class.getResourceAsStream(fileName), if you are using the resources in YourClass. 如果您正在使用YourClass中的资源，则始终最好使用：YourClass.class.getResourceAsStream（fileName）。 This way the resource is searched by the class loader. 这样，类加载器将搜索资源。
