使用java中的slick2D库的xml FileNotFoundException [英] xml FileNotFoundException using slick2D library in java

问题描述

private ConfigurableEmitter emitter;

File xmlFile = new File("ressources/emitter.xml");
emitter = ParticleIO.loadEmitter(xmlFile);

如果我在eclipse中启动项目，一切都会正常工作，但在我导出项目后使用JarSplice创建一个.jar文件，当我使用命令提示符启动jar文件时，程序将崩溃启动FileNotFoundException，说它无法找到指定的路径。

If I launch the project in eclipse, everything will works fine, but after I export my project and use JarSplice to create a .jar file, when I launch the jar file using the command prompt, the program will crash launching a FileNotFoundException, saying it cannot find the path specified.

java.io.FileNotFoundException: ressources\emitter.xml (The system cannot find the
path specified)

令人惊讶的是，在打开xml文件之前，我打开一个与xml文件位于同一位置的.png文件，这没有任何问题。另外，当我打开使用winrar导出的.jar文件时，我可以在ressources文件夹下找到我的xml文件。这可能是什么问题？

The surprising thing is that just before opening the xml file, I open a .png file located at the same place as the xml file, and this without any problem. In addition, when I open the .jar file I exported using winrar, I can find my xml file under the ressources folder. What can be the problem here?

谢谢！

编辑：

带解决方案的代码：

InputStream i=this.getClass().getClassLoader().
    getResourceAsStream("ressources/test.xml");
emitter = ParticleIO.loadEmitter(i);

推荐答案

当您将项目打包到JAR时，您的资源不会t存在于磁盘上，但是被压缩到JAR本身并且你必须作为资源加载。
关于如何使用 ClassLoader.getResourceAsStrem从JAR加载资源，有很多关于SO的指南。 ）（按照链接）

When you pack your project to JAR your resource don't live on disk, but are compressed into the JAR itself and you have to load as resource.
There are a lot of guide on SO on how to load resource from JAR using ClassLoader.getResourceAsStrem() (follow this link)
