javax.xml.transform.TransformerException: java.io.FileNotFoundException: <file_name>(Access is denied)

提问by Ashish Pancholi

I am getting exception at last line of code -

我在最后一行代码中遇到异常 -

Transformer transformer = TransformerFactory.newInstance().newTransformer();
DOMSource xmlSource = new DOMSource(document);

StreamResult result;
File f = new File(sFilePath);
if (f.exists() == false) {
   result = new StreamResult(f);
} else {
   result = new StreamResult(sFilePath);
}

transformer.transform(xmlSource, result);

The exception stacktrace is -

异常堆栈跟踪是 -

Sounds like file permissions on your XML files, doesn't it?

听起来像是对 XML 文件的文件权限，不是吗？

If you're executing from a web context, please bear in mind that the web user (for example, "nobody" under Linux/Apache, or "IUSR_MACHINE" under Windows/IIS) has MINIMAL privileges to access your filesystem.

如果您从 Web 上下文执行，请记住 Web 用户（例如，Linux/Apache 下的“nobody”或 Windows/IIS 下的“IUSR_MACHINE”）具有访问您的文件系统的最低权限。

And this is a Good Thing: especially if your application is exposed to the Internet :)

这是一件好事：尤其是当您的应用程序暴露在 Internet 上时 :)

PS: Also, the directory path you cited doesn't look right:

PS：另外，你引用的目录路径看起来不对：

C:\ProgramData.\config.xml

C:\ProgramData.\config.xml

Are you sure it's not supposed to be "C:\Program Data\config.xml"????

你确定它不应该是“C:\Program Data\config.xml”？？？？

PPS: While we're talking about "file permissions"; Windows Vista, Windows 7 and Server 2008 all have stricter rules against accessing anything in a drive's root (EX: "c:\") or system directories (EX: "c:\windows" or "c:\Program files").

PPS：当我们谈论“文件权限”时；Windows Vista、Windows 7 和 Server 2008 都有更严格的规则，禁止访问驱动器根目录（例如：“c:\”）或系统目录（例如：“c:\windows”或“c:\Program files”）中的任何内容。

Try changing it to use the file's URI.getPath()instead of just passing File object into StreamResult.

尝试将其更改为使用文件的URI.getPath()而不是仅将 File 对象传递到 StreamResult。

eg. StreamResult result = new StreamResult(anOutputFile.toURI().getPath());

例如。 StreamResult result = new StreamResult(anOutputFile.toURI().getPath());

Try checking whether the file you try to transform does have the values and that they are valid.

尝试检查您尝试转换的文件是否确实具有值以及它们是否有效。

May be you are iterating over a set of files using a loop and some times you end up trying to transform files which do not have any value like nullor "".

可能是您正在使用循环遍历一组文件，有时您最终会尝试转换没有任何值的文件，例如null或 ""。

try This

试试这个

file = new File(System.getProperty("user.dir") + "/YOURFILEADDRESS.xml");
