对于类似的功能(从装载Android的照片与Servlet)，这里的Android客户端的代码，我使用(在这里发帖而稍加编辑)：

URI uri = URI.create(// path to file);

MultipartEntity entity = new MultipartEntity(HttpMultipartMode.STRICT);

// several key-value pairs to describe the data, one should be filename

entity.addPart("key", new StringBody("value"));

File inputFile = new File(photoUri.getPath());

// optionally reduces the size of the photo (you can replace with FileInputStream)

InputStream photoInput = getSizedPhotoInputStream(photoUri);

entity.addPart("CONTENT", new InputStreamBody(photoInput, inputFile.getName()));

HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost(uri);

HttpContext localContext = new BasicHttpContext();

httppost.setEntity(entity);

HttpResponse response = httpclient.execute(httppost, localContext);

和这里的代码来接受它。首先，一定要标记您的servlet类为支持多消息：

@MultipartConfig

public class PhotosServlet extends HttpServlet

然后身体的相关部分：

HttpEntity entity = new InputStreamEntity(request.getPart("CONTENT").getInputStream(), contentLength);

InputStream inputFile = entity.getContent();

// string extension comes from one of the key-value pairs

String extension = request.getParameter(//filename key);

// first write file to a file

File images = new File(getServletContext().getRealPath("images"));

File filePath = File.createTempFile("user", extension, images);

writeInputDataToOutputFile(inputFile, filePath); // just copy input stream to output stream

String path = filePath.getPath();

logger.debug("Wrote new file, filename: " + path);

希望它能帮助。
