        ResponseEntity
                response = restTemplate.postForEntity("/user", user, Result.class);

        ObjectMapper objectMapper=new ObjectMapper();
        String content = objectMapper.writeValueAsString(response.getBody().getData());
        User user1 = objectMapper.readValue(content, User.class);
