类StorageService是使用云存储API来存储文件的服务 这是我的代码如何使用java将文件上传到谷歌云存储？
public class UploadFileAction extends org.apache.struts.action.Action {
private static final String SUCCESS = "success";
private StorageService storage = new StorageService();
private static final int BUFFER_SIZE = 1024 * 1024;
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
ServletFileUpload upload = new ServletFileUpload();
FileItemIterator iter = upload.getItemIterator(request);
while (iter.hasNext()) {
FileItemStream item = iter.next();
String fileName = item.getName();
String mime = item.getContentType();
storage.init(fileName, mime);
InputStream is = item.openStream();
byte[] b = new byte[BUFFER_SIZE];
int readBytes = is.read(b, 0, BUFFER_SIZE);
while (readBytes != -1) {
storage.storeFile(b, BUFFER_SIZE);
readBytes = is.read(b, 0, readBytes);
}
is.close();
storage.destroy();
}
return mapping.findForward(SUCCESS);
}
}
package storageservice;
import com.google.appengine.api.files.*;
import com.google.appengine.api.files.GSFileOptions.GSFileOptionsBuilder;
import java.io.*;
import java.nio.channels.Channels;
public class StorageService {
private static final String BUCKET_NAME = "thoitbk";
private FileWriteChannel writeChannel = null;
private OutputStream os = null;
public void init(String fileName, String mime) throws Exception {
FileService fileService = FileServiceFactory.getFileService();
GSFileOptionsBuilder builder = new GSFileOptionsBuilder()
.setAcl("public_read")
.setBucket(BUCKET_NAME)
.setKey(fileName)
.setMimeType(mime);
AppEngineFile writableFile = fileService.createNewGSFile(builder.build());
boolean lock = true;
writeChannel = fileService.openWriteChannel(writableFile, lock);
os = Channels.newOutputStream(writeChannel);
}
public void storeFile(byte[] b, int readSize) throws Exception {
os.write(b, 0, readSize);
os.flush();
}
public void destroy() throws Exception {
os.close();
writeChannel.closeFinally();
}
}
在本地能正常工作，但错误，当我部署我的应用
