关于从android端向服务器端上传文件的问题

[isaactalx]

 RequestParams params = new RequestParams();
                    String urlpath=ConstantData.SERVICE_BASE_URL+"file/mobileupload.do";
                    File file=new File(filePath);
                    AsyncHttpClient client=new AsyncHttpClient();
                    params.put("userName",userName);
                    try {
                        params.put("file",file);
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    }
                    client.post(urlpath, params, new AsyncHttpResponseHandler() {
                        @Override
                        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {

                        }

                        @Override
                        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {

                        }

                        @Override
                        public void onProgress(long bytesWritten, long totalSize) {
                            super.onProgress(bytesWritten, totalSize);
                            int count = (int) ((bytesWritten * 1.0 / totalSize) * 100);
                            uploadButton.setProgress(count);
                        }
                    });

这是客户端上传文件的代码，用的是androidasynchttp的框架

@RequestMapping(value="/mobileupload.do",method=RequestMethod.POST)
	public void moboleUpload(@RequestParam("userName") String userName,@RequestParam("file") MultipartFile file,HttpServletRequest request){
		if(file!=null){
			System.out.println(file.getName());
		}
	}

这是springmvc后台接收文件的方法
我每次点上传文件都会报下面的错误
严重: Servlet.service() for servlet [springmvc] in context with path [/ZTEDocumentServers] threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed.

是哪边写的有问题吗

文件没传上去

我们上传图片的，你可以参照下，把图片换成文件 public class HttpPostFile { public static boolean postFile(File file, String url) throws ClientProtocolException, IOException { FileBody bin = null; HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(url); if (file != null) { bin = new FileBody(file); } // 请记住，这边传递汉字会出现乱码，解决方法如下,设置好编码格式就好 // new StringBody("汉字",Charset.forName("UTF-8"))); StringBody username = new StringBody(""); StringBody password = new StringBody(""); MultipartEntity reqEntity = new MultipartEntity(); reqEntity.addPart("username", username); reqEntity.addPart("password", password); reqEntity.addPart("data", bin); httppost.setEntity(reqEntity); HttpResponse response = httpclient.execute(httppost); if (response.getStatusLine().getStatusCode() == 200) { return true; } else { return false; } } public static void main(String[] args) throws ClientProtocolException, IOException { File file = new File("d:/1.png"); String url = "http://localhost/WeiXinSpring/servlet/DevOpsService?cmd=PtCheckExcelUploadCmd"; System.out.println(postFile(file,url)); } }
