javax.xml.transform.TransformerException：java.io.FileNotFoundException：< file_name>（访问被拒绝） [英] javax.xml.transform.TransformerException: java.io.FileNotFoundException: <file_name>(Access is denied)

问题描述

我在最后一行代码中得到异常 -

I am getting exception at last line of code -

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);

异常堆栈跟踪是 -

The exception stacktrace is -

推荐答案

听起来像你的XML文件的文件权限，不是吗？

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

如果你请记住，网络用户（例如Linux / Apache下的nobody，Windows / IIS下的IUSR_MACHINE）具有访问文件系统的MINIMAL权限。

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.

这是一个好事：特别是如果你的应用程序暴露于互联网：）

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

PS：
此外，您引用的目录路径看起来不正确：

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

C：\ProgramData.\config.xml

C:\ProgramData.\config.xml

你确定是不应该是C：\Program Data\config.xml????

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

PPS：
当我们在谈论文件权限; Windows Vista，Windows 7和Server 2008都有更严格的规则来访问驱动器的根目录（EX：c：\）或系统目录（EX：c：\windows或c：\Program files ）。

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").
