把字符串中的/换成\

[yugongsong]

我从页面获得一个路径 是filePath22 = D:/was/instrall/ 想把他换成filePath22 = D:\was\instrall\


怎么弄啊 我用这个方法不行 filePath22 = filePath22.replaceAll("\\", "////");

用\\\\

[菖蒲老先生]

		String filePath22 = "D:/was/instrall/";
		System.out.println(filePath22.replaceAll("/", "\\\\"));

[wzjmjx]

filePath22.replaceAll("/", "\\\\");

换路径，
private String getFormatPath(String path) {
path = path.replaceAll("\\\\", "/");
path = path.replaceAll("//", "/");
return path;
}
