Question

我正在尝试在带有音频HTML标签的webapp应用程序中侦听动态文件，但是我无法将文件保存在正确的文件夹中...

这是我在eclipse中的文件结构，我想找到所选音频文件夹的路径，而无需对其进行硬编码：

我可以在Controller.java上运行代码，在其中添加： 1）html标记：

<audio controls><source src=\"audio/hello.wav\" type=\"audio/wav\"></audio>

2）为了创建我的文件，我正在使用

    file = new File("/Users/miguelenrile/Desktop/universidad ICAI/master-teleco-1/Primer cuatri/Arq.servicios.de.red/practicas/P10/asrTomcatEjemploCloudant/src/main/webapp/audio/hello2.wav");

显然，这是一个硬编码的目录，一旦目录系统更改，它将不起作用。

我的问题是我需要找到该路径，但是当在互联网上搜索该怎么做时，我却永远也找不到该路径，而是这些行中的某些东西：

/Users/miguelenrile/eclipse-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/asrTomcatEjemploCloudant/

当粘贴到浏览器中时可以使用，但是不会在音频src希望找到的文件中创建文件，因此它将无法使用...

我试图获得前面提到的路径的东西...：

System.out.println("probada: " +getServletContext().getAttribute(ServletContext.TEMPDIR));
System.out.println(getServletContext().getContextPath());
System.out.println(getServletContext().getRealPath(dir));
System.out.println(new File(".").getCanonicalPath());
System.out.println(System.getProperty("user.dir"));
System.out.println(System.getProperty("user.home"));      
System.out.println(this.getClass().getProtectionDomain().getCodeSource().getLocation());
System.out.println(getServletContext().getRealPath("/"));
System.out.println(request.getSession().getServletContext().getRealPath("/"));
System.out.println(request.getContextPath());

所有这些公式都将放在此处：

/Users/miguelenrile/eclipse-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/asrTomcatEjemploCloudant/

不进入前面提到的编码路径...

我不知道我是否缺少任何东西...

总结：

我想要的路径：

/Users/miguelenrile/Desktop/universidad ICAI/master-teleco-1/Primer cuatri/Arq.servicios.de.red/practicas/P10/asrTomcatEjemploCloudant/src/main/webapp/audio/hello2.wav

我要走的路：

/Users/miguelenrile/eclipse-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/asrTomcatEjemploCloudant/

谢谢

将getRealPath（）与音频文件的文档根路径一起用作参数，应该将文件的实际路径交给您。

getServletContext().getRealPath("/audio/hello.wav");

找不到文件夹JAVA macOS的真实路径
