FileSystems.getFileSystem在ZipFileSystemProvider.java：171行抛出FileSystemNotFoundException
我该怎么做才能克服这个问题？ 提前谢谢......
public void copy(File sourceFile){
Path zipfile = Paths.get(sourceFile.getAbsolutePath());
URI uri = URI.create("jar:" + zipfile.toUri());
FileSystem fs = FileSystems.getFileSystem(uri);
Path nf = fs.getPath("new.txt");
.....
}
