POST メソッドを使用して、安らかな Web サービスを実行しようとしています。私のインターフェースの関連部分は次のとおりです。
@Path("/customers")
public interface CustomerResource {
@POST
@Consumes(MediaType.APPLICATION_XML)
public Response createCustomer(InputStream is);
.....
}
実装:
// Create customer
public Response createCustomer(InputStream is) {
logger.debug("In createCustomer");
Customer customer = readCustomer(is);
customer.setId(idCounter.incrementAndGet());
customerDB.put(customer.getId(), customer);
logger.debug("Created customer " + customer.getId());
logger.debug("Out createCustomer");
return Response.created(URI.create("/customers/"
+ customer.getId())).build();
}
クライアントが電話をかける（関連部分）
URL postUrl = new URL("http://localhost:8080/ShoppingApplication/rest/customers");
HttpURLConnection connection =
(HttpURLConnection) postUrl.openConnection();
connection.setDoOutput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/xml");
OutputStream os = connection.getOutputStream();
os.write(newCustomer.getBytes());
os.flush();
