Вопрос по post, request, http, java – Как отправить простой http пост-запрос с параметрами поста в java

который использовал в своем приложении. Это позволяет вам сделать HTTPost. Если бы у меня было время, я бы создал пример POJO, но, надеюсь, вы сможете разобрать код и найти то, что вам нужно.

v.4.x

HttpClient httpClient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost(url);
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("param1", param1Value, ContentType.TEXT_PLAIN);
builder.addTextBody("param2", param2Value, ContentType.TEXT_PLAIN);
HttpEntity multipart = builder.build();
httpPost.setEntity(multipart);
HttpResponse response = httpClient.execute(httpMethod);

где вы делаете пост со страницы HTML, сервлет обрабатывает его и отправляет текстовый ответ ..
