运行.jar时获取getResourceAsStream文件路径 [英] getResourceAsStream filepath while running .jar

问题描述

我的代码：

BufferedInputStream bis =
  new BufferedInputStream(getClass().getResourceAsStream("playerhit.mp3"));

当 playerhit.mp3 文件与正在运行的 MP3.class 在同一个包中。我将其作为.jar运行。如果我将文件路径更改为 /src/data/audio/playerhit.mp3 ，它将不再起作用。在以.jar运行时，是否仍然可以访问不同于文件包根目录的文件路径？

This code works fine when the playerhit.mp3 file is in same package as the MP3.classit is running in. I'm running this as .jar. If though I change the file path to something like /src/data/audio/playerhit.mp3 it doesn't work anymore. Is there anyway to access different filepath than root of the package while running as .jar?

推荐答案

看看 Javadoc for getResourceAsStream（ ...） 。

如果参数以 / 开头，则资源的绝对名称是以下名称的一部分 / 。否则，绝对名称的格式如下：
modified_pa​​ckage_name / name
其中 modified_pa​​ckage_name 是此对象的包名称， / 替换为。。

If the argument begins with a /, then the absolute name of the resource is the portion of the name following the /. Otherwise, the absolute name is of the following form: modified_package_name/name Where the modified_package_name is the package name of this object with / substituted for ..

因此，如果 playerhit.mp3 位于包结构的根目录中，则应将其引用为 /playerhit.mp3 。如果它在 / src / data / audio / 中，你应该使用 /data/audio/playerhit.mp3 - 但请检查JAR文件的内容以确定。

So, if your playerhit.mp3 is in the root of your package structure, you should reference it as /playerhit.mp3. If it's in /src/data/audio/, you should probably use /data/audio/playerhit.mp3 - but check the contents of your JAR file to be sure.
