我正在尝试在服务器上运行 Xuggle 5.4，并且有一个我不知道如何处理的异常。相同的代码在另外两台服务器上运行良好，并且在另一个应用程序（Playframework）下的同一台服务器上运行良好。它在另一个应用程序下运行的事实使我认为这可能是错误的。

错误的根源似乎是 Xuggle 试图创建一个临时文件并且访问被拒绝。我怎样才能知道这是哪里？如前所述，这可能是其他安装已经使用的位置，并且在另一个用户帐户下运行。

这是堆栈跟踪：

然后问题是用于存储二进制文件的临时目录。由于另一个实例创建了这个临时位置，不同用户名下的第二个进程没有访问权限。开发人员现在已经意识到了这个问题。删除临时目录或授予权限可以解决问题

尽管这个问题已经很老了，并且 xuggle 已被弃用，但我想在查看这里的评论后，我仍然会向其他人展示我是如何解决这个问题的。

可以设置 java.io.tmpdir 属性，而不是删除文件夹或更改其权限。

像这样的例子：

java -Djava.io.tmpdir="~/custom/tempdir/" HelloWorld

背景：

正如另一个答案的评论所建议的那样，将问题的根源追溯到创建相关临时文件夹的函数，表明 java 使用可以自定义的默认位置。

public static File createTempFile(String prefix,
                                  String suffix,
                                  File directory)
                           throws IOException

在指定目录中创建一个新的空文件，使用给定的前缀和后缀字符串生成其名称。如果此方法成功返回，则保证：

  1. 返回的抽象路径名表示的文件在调用此方法之前不存在，并且
  2. 此方法及其任何变体都不会在虚拟机的当前调用中再次返回相同的抽象路径名。

[...]

如果目录参数为空，则将使用系统相关的默认临时文件目录。默认临时文件目录由系统属性 java.io.tmpdir 指定。在 UNIX 系统上，该属性的默认值通常是“/tmp”或“/var/tmp”；在 Microsoft Windows 系统上，它通常是“C:\WINNT\TEMP”。调用 Java 虚拟机时，可以为该系统属性赋予不同的值，但不保证对该属性的编程更改对该方法使用的临时目录有任何影响。

看：

  1. JavaDoc createTempFile（字符串，字符串，文件）
  2. 旧版 Google 网上论坛讨论
