org.springframework.web.client.HttpClientErrorException: 400 Richiesta errata

Uso lo stivale a molla. Ho una pausa POST chiamata che ho bisogno di inviare il corpo utilizzando x-www-form-urlencoded, non ci sono intestazioni necessarie per la chiamata. Posso colpire questo url dal postino e una riga viene creata correttamente in db. Ma quando provo a chiamare questo da Java lato sto ricevendo un 400 eccezione richiesta cattiva.org.springframework.web.client.HttpClientErrorException: 400 Richiesta errata

Qui di seguito è quello che ho provato in Java.

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(); 
     }

Ricevo questa eccezione.

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

Ho anche provato come sotto e ottenuto la stessa eccezione.

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

Ecco lo stacktrace piena

Come posso risolvere questo problema?

Prova utilizzando il metodo postForObject invece di scambio –

Con postino, che hai inviato cinque 'param1' come il corpo della forma, ma con RestTemplate si sta inviando' param1', 'param2', ... –

@AliDehghani ho appena modificati dato che non volevo usare i parametri attuali, è solo per un esempio. Nello scenario reale i parametri sono gli stessi in entrambi i casi. – Arun

Questo è ciò che ha funzionato per me. Il problema è precedente Non ho impostato Content Type (intestazione) quando ho usato il metodo di scambio.

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 e ExternalCallServerErrorException sono le eccezioni personalizzate qui.

Nota: Ricordare che HttpClientErrorException viene emessa quando viene ricevuto un errore 4xx. Pertanto, se la richiesta inviata non corrisponde all'intestazione dell'impostazione o all'invio di dati errati, potresti ricevere questa eccezione.
