org.springframework.web.client.HttpClientErrorException：400 Bad Request

スプリングブーツを使用しています。残りのAPI[〜＃〜] post [〜＃〜]呼び出しがあり、x-www-form-urlencodedを使用して本文を送信する必要があります、呼び出しに必要なヘッダーはありません。郵便配達員からこのURLにアクセスすると、dbに行が正常に作成されます。しかし、Java sideからこれを呼び出そうとすると、400の悪いリクエスト例外が発生します。

以下は、Javaで試したことです。

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
        map.add("param1", "123");
        map.add("param2", "456");
        map.add("param3", "789");
        map.add("param4", "123");
        map.add("param5", "456");

    HttpHeaders headers = new HttpHeaders();
    final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map,
                headers);

        try {
            RestTemplate restTemplate = new RestTemplate();
            String response = restTemplate.postForObject(
                    "https://url", entity,
                    String.class);

            System.out.println(response);
        } catch (final Exception e) {
            throw new RuntimeException();
        }

この例外が発生しています。

org.springframework.web.client.HttpClientErrorException: 400 Bad Request

私も下のようにしてみましたが、同じ例外がありました。

ResponseEntity<String> x = restTemplate.exchange("https://url", HttpMethod.POST,
                    map, String.class);

どうすれば修正できますか？

これは私のために働いたものです。問題は、交換方法を使用したときにコンテンツタイプ（ヘッダー）を設定しなかった以前です。

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

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

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    }

ExternalCallBadRequestExceptionとExternalCallServerErrorExceptionは、ここでのカスタム例外です。

注：4xxエラーを受信すると、HttpClientErrorExceptionがスローされることに注意してください。したがって、送信するリクエストがヘッダーの設定または間違ったデータの送信のいずれかである場合、この例外を受け取る可能性があります。
