Httpclient MultipartEntity is deprecated

HttpClient是apache提供的很方面的java http客户端，它可以模拟浏览器发送请求，get、post、head等。我们在提交post表单时，表单中如果需要上传文件，那么表单的类型一般是**enctype="multipart/form-data"，HttpClient也提供这种方法，需要用到http-mime.jar这个包。

MultipartEntity mutiEntity = newMultipartEntity();
File file = new File("d:/photo.jpg");
mutiEntity.addPart("desc",new StringBody("你好吗？", Charset.forName("utf-8")));
mutiEntity.addPart("pic", newFileBody(file));

httpPost.setEntity(mutiEntity);

在比较新的httpmime包中，MultipartEntity这个类已经不推荐使用了，推荐使用下面的方式：

    MultipartEntityBuilder builder = MultipartEntityBuilder.create();

    /* example for setting a HttpMultipartMode */
    builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

    /* example for adding an image part */
    FileBody fileBody = new FileBody(new File("")); //image should be a String
    builder.addPart("my_file", fileBody);
    HttpEntity entity = builder.build();

    httpPost.setEntity(entity);
