Jersey REST客户端：如何将XML文件添加到POST请求的正文中？

您始终可以在Java SE中使用java.net API：

URL url = new URL("http://localhost:8080/api/resource");HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setDoOutput(true);connection.setInstanceFollowRedirects(false);connection.setRequestMethod("POST");connection.setRequestProperty("Content-Type", "application/xml");OutputStream os = connection.getOutputStream();TransformerFactory tf = TransformerFactory.newInstance();Transformer transformer = tf.newTransformer();FileReader fileReader = new FileReader("filename.xml");StreamSource source = new StreamSource(fileReader);StreamResult result = new StreamResult(os);transformer.transform(source, result);os.flush();connection.getResponseCode();connection.disconnect();
