使用 java 代码在 activiti-rest 中部署流程定义时出错

Question

大家好，我正在尝试使用 java rest.But 在 activiti-rest 中部署流程定义，但出现 'Exception in thread "main" Bad Request (400)' 错误。我在 google 中尝试了很多但没有找到 that.Please 的任何解决方案帮助我在我的 java 代码和错误下方的 code.Find 中的实际故障在哪里。

我的错误

我的Java代码

/**
*Client Resource
*/
private static ClientResource getClientResource(String uri){
 ClientResource resource=new ClientResource("http://localhost:8431/activiti-rest/service");
 resource.setChallengeResponse(ChallengeScheme.HTTP_BASIC,kermit,kermit);
 return resource;
}

/**
 * Creating Deployment
 */
public static JSONObject createdeployment(){
 String uri=REST_URI+"/repository/deployments";
 log.debug("uri(Create Deploymnet):: "+uri);
 JSONObject my_data=new JSONObject();
 try {
  my_data.put("name","BuyTicket.bpmn20.xml");
  Representation response=getClientResource(uri).post(my_data);
  JSONObject object=new JSONObject(response.getText());
  if(object!=null){
    log.info("Deployed Successfully.....");
    return object;
  }
  
 } catch (JSONException e) {
  e.printStackTrace();
 } catch (IOException e) {
  e.printStackTrace();
 }
 return null;
}

cfr。 http://activiti.org/userguide/index.html#_create_a_new_deployment：正文不应是 json multipart/form-data 文件，而是 bpmn20.xml 文件（或 .zip，如果有多个文件）
