本文整理了Java中org.apache.commons.io.FilenameUtils类的一些代码示例，展示了FilenameUtils类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。FilenameUtils类的具体详情如下：
包路径：org.apache.commons.io.FilenameUtils
类名称：FilenameUtils
[英]General filename and filepath manipulation utilities.
When dealing with filenames you can hit problems when moving from a Windows based development machine to a Unix based production machine. This class aims to help avoid those problems.
NOTE: You may be able to avoid using this class entirely simply by using JDK java.io.File objects and the two argument constructor java.io.File#File(java.io.File,java.lang.String).
Most methods on this class are designed to work the same on both Unix and Windows. Those that don't include 'System', 'Unix' or 'Windows' in their name.
Most methods recognise both separators (forward and back), and both sets of prefixes. See the javadoc of each method for details.
This class defines six components within a filename (example C:\dev\project\file.txt):
This class only supports Unix and Windows style names. Prefixes are matched as follows:
Windows:
a\b\c.txt --> "" --> relative
\a\b\c.txt --> "\" --> current drive absolute
C:a\b\c.txt --> "C:" --> drive relative
C:\a\b\c.txt --> "C:\" --> absolute
\\server\a\b\c.txt --> "\\server\" --> UNC
Unix:
a/b/c.txt --> "" --> relative
/a/b/c.txt --> "/" --> absolute
~/a/b/c.txt --> "~/" --> current user
~ --> "~/" --> current user (slash added)
~user/a/b/c.txt --> "~user/" --> named user
~user --> "~user/" --> named user (slash added)Both prefix styles are matched always, irrespective of the machine that you are currently running on.

[中]通用文件名和文件路径操作实用程序。
在处理文件名时，从基于Windows的开发机器转移到基于Unix的生产机器时，可能会遇到问题。本课程旨在帮助避免这些问题。
注意：通过使用JDK java，您可以完全避免使用这个类。木卫一。文件对象和双参数构造函数。木卫一。File#File（java.io.File，java.lang.String）。
这个类上的大多数方法都被设计为在Unix和Windows上工作相同。名称中不包含“系统”、“Unix”或“Windows”的。
大多数方法同时识别分隔符（向前和向后）和两组前缀。有关详细信息，请参见每个方法的javadoc。
此类在文件名中定义了六个组件（例如C:\dev\project\file.txt）：
*前缀-C：
*路径为-dev\project
*完整路径-C:\dev\project
*名称-文件。文本
*基本名称-文件
*扩展名为-txt
请注意，如果目录文件名以分隔符结尾，则此类的效果最好。如果省略最后一个分隔符，则无法确定文件名是否对应于文件或目录。因此，我们选择说它对应于一个文件。
此类仅支持Unix和Windows样式名称。前缀匹配如下：
Windows:
a\b\c.txt --> "" --> relative
\a\b\c.txt --> "\" --> current drive absolute
C:a\b\c.txt --> "C:" --> drive relative
C:\a\b\c.txt --> "C:\" --> absolute
\\server\a\b\c.txt --> "\\server\" --> UNC
Unix:
a/b/c.txt --> "" --> relative
/a/b/c.txt --> "/" --> absolute
~/a/b/c.txt --> "~/" --> current user
~ --> "~/" --> current user (slash added)
~user/a/b/c.txt --> "~user/" --> named user
~user --> "~user/" --> named user (slash added)无论您当前运行的机器是什么，这两种前缀样式始终匹配。
