org.springframework.web.client.HttpClientErrorException: 400 Bad Request
我正在使用弹簧靴。 我有一个rest api POST调用，我需要使用x-www-form-urlencoded发送正文，该调用不需要头。 我可以从邮递员访问此URL，并且在db中成功创建了一行。 但是，当我尝试从Java端调用此函数时，出现了400错误的请求异常。
以下是我在Java中尝试过的方法。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | 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(); } |
我遇到这个例外。
1 |
我也尝试如下，并得到相同的例外。
1 2 | ResponseEntity<String> x = restTemplate.exchange("https://url", HttpMethod.POST, map, String.class); |
这是完整的堆栈跟踪

我该如何解决？
这对我有用。 问题是较早的，当我使用交换方法时，我没有设置Content Type(header)。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | 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); } |
在这里，ExternalCallBadRequestException和ExternalCallServerErrorException是自定义异常。
注意：请记住，当收到4xx错误时，抛出HttpClientErrorException。 因此，如果发送的请求在设置标头或发送错误的数据时出错，则可能会收到此异常。
