Question

我正在使用Apache CXF RESTful webservice上传文件，同时发送JSON数据，如下所示：

public class DownLoadImageAsyncTask extends AsyncTask{

        @Override
        protected void onPreExecute() {
            progressDialog=new ProgressDialog(TwitterIntegration.this);
            progressDialog.setCancelable(false);
            progressDialog.setMessage(getString(R.string.please_wait));
            progressDialog.setIndeterminate(true);
            if(Validator.isNotNull(preferences.getImagePath())&& !preferences.getImagePath().isEmpty()){
                preferences.getImagePath().clear();
            }
            filePath=preferences.getImagePath();
        }

        @Override
        protected Object doInBackground(Object[] params) {

            File file=new File(Environment.getExternalStorageDirectory(),"/HealthWel");
            if(file.exists()==true){
                file.delete();
            }
            file.mkdir();
            for (int i=0;i<mURLs.size();i++){
                File f=new File(file+"/"+i+".jpg");
                if(f.exists()==true){
                    f.delete();
                }
                if(f.exists()==false){
                    HttpClient httpClient=new DefaultHttpClient();
                    HttpGet httpGet=new HttpGet(mURLs.get(i));
                    try {
                        HttpResponse httpResponse=httpClient.execute(httpGet);
                        if(httpResponse.getStatusLine().getStatusCode()==200){
                            HttpEntity httpEntity=httpResponse.getEntity();
                            InputStream is=httpEntity.getContent();
                            Boolean status=f.createNewFile();
                            FileOutputStream fileOutputStream=new FileOutputStream(f);
                            byte[]buffer=new byte[1024];
                            long total=0;
                            int count;
                            while ((count=is.read(buffer))!=-1){
                                total+=count;
                                fileOutputStream.write(buffer,0,count);
                            }
                            if(!downLoad) {
                                if (Validator.isNotNull(preferences.getImagePath()) && !preferences.getImagePath().isEmpty()) {
                                    preferences.getImagePath().clear();
                                }
                            }

                            filePath.add(f.getPath());
                            fileOutputStream.close();
                            is.close();
                            runOnUiThread(new Runnable() {
                                public void run() {
                                    // runs on UI thread
                                    progressDialog.show();
                                }
                            });

                        }
                        else {
                            finish();
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }
            return null;
        }

        @Override
        protected void onPostExecute(Object o) {
            preferences.setImagePath(filePath);
            dismissProgressDialog();
            shareImage();
        }
    }

    private void showProgressDialog() {
        if(!isFinishing() && progressDialog==null) {
            progressDialog = new ProgressDialog(this);
            progressDialog.setCancelable(false);
            progressDialog.show();

        }

    }

    /**
     * dismiss Progress Dialog.
     */
    private void dismissProgressDialog() {
        if (!isFinishing() &&progressDialog!=null && progressDialog.isShowing()) {
            progressDialog.dismiss();
            progressDialog=null;
        }
    }

我正在使用REST客户端发送JSON数据和文件。当我发送请求时，我得到了foll错误：

@POST
    @Path( "/upload/doc" )
    @Consumes( { MediaType.MULTIPART_FORM_DATA, MediaType.APPLICATION_JSON })
    @Produces( MediaType.APPLICATION_JSON )
    public Response uploadRateSheet( @Multipart( value = "file" ) Attachment attachment, DocumentApiModel doc)
    {
        ...

}

请帮忙......

谢谢。

我相信你不能将附件和身体一起发送（在CXF webclient，chrome postman和restclient中验证），你可以分别发送附件或身体。
因此更新了多个部分的休息定义。
接下来要应用提供商的CXF，它必须知道每个部分的内容类型是什么，
因此设置内容类型。

通过以上两项更改，您的REST方法声明将如下所示。

@POST
@Path( "/upload/doc" )
@Consumes( { MediaType.MULTIPART_FORM_DATA})
@Produces( MediaType.APPLICATION_JSON )
public Response uploadRateSheet( 
      @Multipart( value = "file",type="application/octet-stream") Attachment attachment, //Note set content type accordinly such that if any available providers for that content type is present it can resolve your attachment implicitly to avoid writing custom code.
      @Multipart( value = "docModel",type="application/json") DocumentApiModel doc);

接下来请确保您已启用Jettission或Jackson等JSON提供程序

例如Jackson Json提供者

<jaxrs:providers>
   <bean class="com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider"/>
</jaxrs:providers>

最后测试，请注意你必须使用文件设置这两个部分，当你选择String时，似乎rest客户端没有在Content-Disposition中设置内容类型。

或者，您可以使用CXF Webclient进行测试。

@Test
public void testMultipart() throws FileNotFoundException{

    WebClient client = WebClient.create("<your service url>", Arrays.asList(new JacksonJaxbJsonProvider()));
    client.type("multipart/form-data");
    final Attachment attachment = new Attachment("file", new FileInputStream("<your file>"), new ContentDisposition(("attachment;filename=filename")));
    final Attachment attachment1 = new Attachment("docModel","application/json",new DocumentApiModel());
    client.post(new MultipartBody(Arrays.asList(attachment, attachment1)));

}
