如何在Java中查找与通配符字符串匹配的文件？ [英] How to find files that match a wildcard string in Java?

问题描述

这应该很简单。如果我有这样的字符串：

This should be really simple. If I have a String like this:

../Test?/sample*.txt

那么获得与此模式匹配的文件列表的普遍接受的方法是什么？ （例如，它应匹配 ../ Test1 / sample22b.txt 和 ../ Test4 / sample-spiffy.txt 但不是 ../ Test3 / sample2.blah 或 ../ Test44 / sample2.txt ）

then what is a generally-accepted way to get a list of files that match this pattern? (e.g. it should match ../Test1/sample22b.txt and ../Test4/sample-spiffy.txt but not ../Test3/sample2.blah or ../Test44/sample2.txt)

我看过 org.apache.commons.io.filefilter.WildcardFileFilter 它似乎是正确的野兽，但我不知道如何使用它来查找相对目录路径中的文件。

I've taken a look at org.apache.commons.io.filefilter.WildcardFileFilter and it seems like the right beast but I'm not sure how to use it for finding files in a relative directory path.

我想我可以查看ant的源代码，因为它使用了通配符语法，但我必须在这里遗漏一些非常明显的东西。

I suppose I can look the source for ant since it uses wildcard syntax, but I must be missing something pretty obvious here.

（编辑：上面的例子只是一个示例。我正在寻找在运行时解析包含通配符的常规路径的方法我根据mmyers的建议想出了如何做到这一点，但这有点烦人。更不用说java JRE似乎在自动解析简单的通配符了main（String []参数）从单个参数保存我的时间和麻烦......我很高兴我没有混合中的非文件参数。）

(edit: the above example was just a sample case. I'm looking for the way to parse general paths containing wildcards at runtime. I figured out how to do it based on mmyers' suggestion but it's kind of annoying. Not to mention that the java JRE seems to auto-parse simple wildcards in the main(String[] arguments) from a single argument to "save" me time and hassle... I'm just glad I didn't have non-file arguments in the mix.)

推荐答案

考虑来自Apache Ant的DirectoryScanner：

Consider DirectoryScanner from Apache Ant:

DirectoryScanner scanner = new DirectoryScanner();
scanner.setIncludes(new String[]{"**/*.java"});
scanner.setBasedir("C:/Temp");
scanner.setCaseSensitive(false);
scanner.scan();
String[] files = scanner.getIncludedFiles();

你需要引用ant.jar（对于ant 1.7.1，大约1.3 MB）。

You'll need to reference ant.jar (~ 1.3 MB for ant 1.7.1).
