filenameutils

又是一个很有用的工具类

String filename = "C:/commons/io/../lang/project.xml";
		//String filename = "src\\test\\resources\\hello.htm";
		String normalized = normalize(filename);
		System.out.println(normalized);//取相对路径
		//System.out.println(separatorsToSystem(filename));
		System.out.println(getName(filename));//取文件名
		//System.out.println(getFullPathNoEndSeparator(filename));//取文件名前面的路径
		System.out.println(getPathNoEndSeparator(filename));//取文件名前面的路径
		System.out.println(separatorsToUnix(filename));//把分割符号都转成unix的
