spring - 实体的 RestTemplate 帖子

Question

我的 post 方法被调用，但我的个人资料为空。这种方法有什么问题？我必须使用 @Requestbody 来使用 RestTemplate 吗？

Profile profile = new Profile();
profile.setEmail(email);        
String response = restTemplate.postForObject("http://localhost:8080/user/", profile, String.class);


@RequestMapping(value = "/", method = RequestMethod.POST)
    public @ResponseBody
    Object postUser(@Valid Profile profile, BindingResult bindingResult, HttpServletResponse response) {

    //Profile is null
        return profile;
    }

Answer 1

您必须以这种方式构建配置文件对象

MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();
parts.add("email", email);

Object response = restTemplate.postForObject("http://localhost:8080/user/", parts, String.class);

Answer 2

MultiValueMap对我来说是一个很好的起点，但在我的情况下，它仍然将空对象发布到@RestController我的实体创建解决方案中，并且发布最终看起来像这样：

HashedMap requestBody = new HashedMap();
requestBody.put("eventType", "testDeliveryEvent");
requestBody.put("sendType", "SINGLE");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);

// Jackson ObjectMapper to convert requestBody to JSON
String json = new ObjectMapper().writeValueAsString(request);
HttpEntity<String> entity = new HttpEntity<>(json, headers);

restTemplate.postForEntity("/generate", entity, String.class);

我目前的做法：

final Person person = Person.builder().name("antonio").build();

final ResponseEntity response = restTemplate.postForEntity(
         new URL("http://localhost:" + port + "/person/aggregate").toString(),
         person, Person.class);
