无法使用 Javafx MediaPlayer 播放 wav 或 mp3 文件。也无法使用本机 java 库播放 wav 文件
Can't play wav or mp3 files with Javafx MediaPlayer. Also can't play wav files with the native java library
我有一个 java 项目，我必须制作一个可以播放 wav 或 mp3 文件的音乐播放器。但是，我无法使用 Javafx 库或本机 java 库播放我的 wav 或 mp3 文件。我已经检查并确保我用来测试的 wav 和 mp3 文件没有损坏。我正在使用 Javafx 17.0.2 和 JDK 11.

我无法重现您的问题。
你的问题是环境问题，具体是什么我不能说。
我建议在 idea 中创建一个新项目并按照我所做的相同步骤进行操作，只要文件路径正确，它就应该可以工作。
这些是我为允许媒体使用您的示例应用程序播放而遵循的步骤：
在 Windows 11.
使用 OpenJDK 17.0.2 和 JavaFX 17.0.2 创建了一个 new JavaFX project in Idea
Copy-and-pasted将您的 JavaFX 示例代码放入新项目中。
按照说明将媒体处理添加到项目中：
已下载您的 mp3 和 wav 文件。
依次设置文件路径。
运行 应用程序并点击每个文件的播放按钮。
MP3 和 WAV 文件都可以正常播放。
你四月的谎言很好，我会努力学习的
