我得到以下 IOException :
java.io.IOException: Access is denied
at java.io.WinNTFileSystem.createFileExclusively(Native Method)
at java.io.File.createNewFile(File.java:850)
at zipUnzipper.main(zipUnzipper.java:41)
尝试运行以下代码时:
public class zipUnzipper {
public zipUnzipper() {
}
public static void main(String[] args){
//Unzip to temp folder. Add all files to mFiles. Print names of all files in mFfiles.
File file = new File("C:\\aZipFile.zip");
String filename = file.getName();
String filePathName = new String();
int o = filename.lastIndexOf('.');
filename = filename.substring(0,o);
try {
ZipFile zipFile = new ZipFile (file.getAbsoluteFile());
Enumeration entries = zipFile.entries();
while(entries.hasMoreElements()) {
ZipEntry zipEntry = (ZipEntry) entries.nextElement();
System.out.println("Unzipping: " + zipEntry.getName());
BufferedInputStream bis = new BufferedInputStream(zipFile.getInputStream(zipEntry));
byte[] buffer = new byte[2048];
filePathName = "C:\\TEMP\\"+filename+"\\";
File fileToWrite = new File(filePathName+ zipEntry.getName());
fileToWrite.mkdirs();
fileToWrite.createNewFile();
FileOutputStream fos = new FileOutputStream(fileToWrite);
BufferedOutputStream bos = new BufferedOutputStream( fos , buffer.length );
int size;
while ((size = bis.read(buffer, 0, buffer.length)) != -1) {
bos.write(buffer, 0, size);
}
bos.flush();
bos.close();
bis.close();
}
zipFile.close();
File folder = new File (filePathName);
File [] mFiles = folder.listFiles();
for (int x=0; x<mFiles.length; x++) {
System.out.println(mFiles[x].getAbsolutePath());
}
} catch (ZipException ze) {
ze.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}
在我看来,由于某种原因,JVM 无法创建新文件。如果文件已经存在,则代码运行良好。是否有某种访问文件指示 JVM 是否可以创建新文件,或者我只是做错了什么?
任何帮助深表感谢 :-)
我正在运行 Java 1.4,并且一直在 Windows XP 中的 JDeveloper 中进行测试。
