原始答案

以下是使用Java SE API(包括JAXB)调用RESTful服务的示例：

String uri =

"http://localhost:8080/CustomerService/rest/customers/1";

URL url = new URL(uri);

HttpURLConnection connection =

(HttpURLConnection) url.openConnection();

connection.setRequestMethod("GET");

connection.setRequestProperty("Accept", "application/xml");

JAXBContext jc = JAXBContext.newInstance(Customer.class);

InputStream xml = connection.getInputStream();

Customer customer =

(Customer) jc.createUnmarshaller().unmarshal(xml);

connection.disconnect();
