我有以下代码用于使用Apache的HTTP-Client(org.apache.http.client)上传文件:

  public static void main(String[] args) throws Exception

    File file = new File(fileName);

    String serverResponse = null;
    HttpParams params = new BasicHttpParams();
    params.setParameter(HttpProtocolParams.USE_EXPECT_CONTINUE, true);
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    HttpClient client = new DefaultHttpClient(params);
    HttpPut put = new HttpPut("http://localhost:8080/" + fileName);

    FileEntity fileEntity = new FileEntity(file, "binary/octet-stream");
    put.setEntity(fileEntity);   

    HttpResponse response = client.execute(put);
    HttpEntity entity = response.getEntity();
    if (entity != null)
    {
      serverResponse = EntityUtils.toString(entity);
      System.out.println(serverResponse);
    }
  }

它工作得很好,但现在我想要一个进度条,显示文件上传的进度.怎么做到这一点？我在File Upload with Java(带进度条)中找到了一个代码片段,但是它是为Apache HTTP Client 3(org.apache.commons.httpclient)设计的,并且Apache HTTP Client …
