java如何向HTTPRequest发送JSON对象并接收JSON响应

Question

我正在使用JAVA语言来完成这个任务

我创建了一个对象，我希望以JSON格式发送数据作为POST请求，并接收JSON响应

这是我的密码

CreditCardDetail creditCard = new CreditCardDetail("DummyPerson", "5433334344", 04, 2023, 567);

ObjectMapper mapper = new ObjectMapper();

String json = mapper.writeValueAsString(creditCard);

HttpRequest request = HttpRequest.newBuilder().uri(URI.create(uri))
            .POST(BodyPublishers.ofString(json)).build();


HttpResponse<String> response = client.send(request, BodyHandlers.ofString());
