java - 为什么没有 glob :* match any path in PathMatcher?

Question

让我们:

Path path = Paths.get("C:\\1.txt");

以下代码打印“true”:

PathMatcher matcher = FileSystems.getDefault().getPathMatcher("regex:.*");
System.out.println(matcher.matches(path));

但以下代码打印“false”:

PathMatcher matcher = FileSystems.getDefault().getPathMatcher("glob:*");
System.out.println(matcher.matches(path));

为什么？

我期望这两种方法都具有true。

根据Glob page from Wikipedia ，通配符*的意思是:

matches any number of any characters including none

详细信息:

• Java 8
• Windows 7

正如 @T.J Crowder 所说，你应该很好地接受这个:

PathMatcher matcher2 = FileSystems.getDefault().getPathMatcher("glob:**");
System.out.println(matcher2.matches(path));

有关更多信息，请参阅 this其中说:

The ** characters matches zero or more characters crossing directory boundaries.
