DocsService client = new DocsService("service name");
client.setUserCredentials(username,password);
File file = new File(filename);
URL url = new URL("https://docs.google.com/feeds/default/private/full/?ocr=true&convert=true");
String mimeType = DocumentListEntry.MediaType.fromFileName(file.getName()).getMimeType();
DocumentEntry newDocument = new DocumentEntry();
newDocument.setTitle(new PlainTextConstruct(file.getName()));
newDocument.setMediaSource(new MediaFileSource(file, mimeType));
//newDocument.setFile(file, mimeType);
newDocument = client.insert(url, newDocument);
System.out.println("uploaded "+file.getName());

As far as I know (its been a few month since I looked) this is not (yet?) supportedby the google drive API. As a workaround consider installing the native google drive share and write the files you want to upload into the locally mapped shared folder. Then its google drives problem to handle the upload.
据我所知（自从我看了几个月以来）这不是（还？）谷歌驱动器 API支持的。作为一种解决方法，请考虑安装本机 google 驱动器共享并将要上传的文件写入本地映射的共享文件夹。然后它的谷歌驱动器问题来处理上传。

I know this question is quite old ,but now google has official support for Java drive api,there is a quick sample to start integrating Drive API with java application. Download drive API client jar files from here
我知道这个问题已经很老了，但现在谷歌官方支持Java drive api，有一个快速示例可以开始将 Drive API 与 java 应用程序集成。从这里下载驱动 API 客户端 jar 文件
and if you are developing your application from Java SE don't forget to put servlet api.jar on class path or else you will end up with lot of errors.
如果您正在从 Java SE 开发您的应用程序，请不要忘记将 servlet api.jar 放在类路径上，否则您最终会遇到很多错误。
