我这样做:
private boolean createCopy(String targetDirectory, String[] dataSet, String fileName, boolean overwrite) throws IOException, URISyntaxException
{
fileName = "file:" + fileName.replace(" ","%20");
URI uri = new URI("file:" + targetDirectory);
Path dPath = Paths.get(uri);
//code
}
我得到了这个例外:
Exception in thread "main" java.lang.IllegalArgumentException: URI is not hierarchical
at sun.nio.fs.WindowsUriSupport.fromUri(WindowsUriSupport.java:122)
at sun.nio.fs.WindowsFileSystemProvider.getPath(WindowsFileSystemProvider.java:92)
at java.nio.file.Paths.get(Paths.java:138)
...
在
Path dPath = Paths.get(uri);
线。任何人都知道为什么会这样? targetDirectory
只是一个简单的文件夹,既不是JAR
也不是WAR
文件;如果我取消
URI uri = new URI("file:" + targetDirectory);
我得到了
Exception in thread "main" java.nio.file.FileSystemNotFoundException: Provider "DRIVE_LETTER" not installed
at java.nio.file.Paths.get(Paths.java:147)
...
"DRIVE_LETTER"
最终变得类似于" C"或" D"或" E"。它是targetDirectory
所在的驱动器。
编辑:
public static void main(String... args)
{
Path path = null;
try
{
Paths.get(new URI("file:E://HTML%20Processor//test//copies//"));
}
catch (URISyntaxException e)
{
e.printStackTrace();
}
}
抛出完全相同的异常,因为您想知道确切的呼叫。
编辑:将文件放在任何其他驱动器上没有任何区别; USB或SATA驱动器也没有区别。

它应该是file:// not file:
