访问JAR资源 [英] Accessing JAR resources

问题描述

我有一个 jar 文件，其中包含我要分发的资源（主要是缓存，日志记录等配置）。

I have a jar file with resources (mainly configuration for caches, logging, etc) that I want to distribute.

我遇到了这些资源的相对路径问题，所以我做了我在另一个stackoverflow问题中发现的问题，该问题说这是一种有效的方式：

I'm having a problem with the relative paths for those resources, so I did what I've found in another stackoverflow question, which said that this was a valid way:

ClassInTheSamePackageOfTheResource.class.getResourceAsStream('resource.xml');

可悲的是，这不起作用。

Sadly this does not work.

有任何想法吗？谢谢！

PS：显然我不能使用绝对
路径，我想避免
环境变量如果可能

PS: Obviously I cannot use absolute paths, and I'd like to avoid environment variables if possible

推荐答案

确保资源文件夹在项目中列为源文件夹设置。另外，确保在构建jar时将资源文件夹设置为export。

Make sure that your resource folder is listed as a source folder in your project settings. Also, make sure that the resource folder is set to export when you build your jar.

您可以在jar文件中添加.zip扩展名，然后将其打开以确保您的资源包含在预期的位置。

You can add a .zip extension to your jar file then open it up to ensure that your resources are included and at the expected location.

我总是使用这样的绝对路径：

I always use absolute paths like this:

InputStream input = this.getClass().getResourceAsStream("/image.gif");

使用绝对路径时，/是jar文件中的根文件夹，而不是根文件夹主机的文件夹。

When you use absolute paths, "/" is the root folder in the jar file, not the root folder of the host machine.
