我正在使用ZipOutputStream,FileOutputStream和FileInputStream.
首先我创建了一个包含一个文件的文件夹它成功创建了.然后我尝试创建zip文件.动态地,它首次正确创建文件,但第二次,第三次在打开文件时出错.
Error: zip [path/././file.zip] Cannot open The process cannot access the file because it is being used by another process.
I created following code in java,
我的代码：
demopath+="/myzip"+po.getPoid();
createDir(demopath);
createFileForFamilies("My content", demopath+"/file");
this.zipDirectory(new File(demopath), demopath+".zip");
我的文件创建者功能：
public String createFileForFamilies(String content, String path) {
FileOutputStream fop = null;
File file;
try {
file = new File(path);
fop = new FileOutputStream(file);
// if file doesnt exists, then create it
if (!file.exists()) {
file.createNewFile();
}
// get the content in bytes
byte[] contentInBytes = content.getBytes();
fop.write(contentInBytes);
fop.flush();
fop.close();
return ("Done");
} catch (IOException e) {
System.err.println(e);
return ("Done");
} finally {
try {
if (fop != null) {
fop.close();
}
} catch (IOException e) {
System.err.println(e);
return ("Abort");
}
}
}
我的Zip创建功能：
public void zipDirectory(File dir, String zipDirName) {
try {
populateFilesList(dir);
//now zip files one by one
//create ZipOutputStream to write to the zip file
FileOutputStream fos = new FileOutputStream(zipDirName);
ZipOutputStream zos = new ZipOutputStream(fos);
for (String filePath : filesListInDir) {
System.out.println("Zipping " + filePath);
//for ZipEntry we need to keep only relative file path, so we used substring on absolute path
ZipEntry ze = new ZipEntry(filePath.substring(dir.getAbsolutePath().length() + 1, filePath.length()));
zos.putNextEntry(ze);
//read the file and write to ZipOutputStream
FileInputStream fis = new FileInputStream(filePath);
byte[] buffer = new byte[1024];
int len;
while ((len = fis.read(buffer)) > 0) {
zos.write(buffer, 0, len);
}
zos.closeEntry();
fis.close();
}
zos.close();
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
