但是如果因为一个错误的请求(5xx)或4xx而出现异常( HttpStatusCodeException ),在HttpStatusCodeException的catch块中,我得到的response(见上)为null,因此我无法访问我在web服务中设置的自定义标头。在RestTemplate中出现异常的情况下,如何从响应中获取自定义headers。 另一个问题是,我在响应体中设置了一个错误对象(Js...
UnknownHttpStatusCodeException:表示在与RESTful服务进行通信时遇到未知的HTTP状态码。 RestClientException的优势在于提供了一种统一的异常处理机制,使得开发人员可以更好地处理与RESTful服务的通信过程中可能出现的各种异常情况。 应用场景:在使用Spring Framework进行RESTful API调用时,如果发生了与服务端通信相关的异常,可以...
catch (final Exception ex) { if (ex instanceof HttpClientErrorException) { HttpClientErrorException hcee = (HttpClientErrorException)ex; if(hcee.getStatusCode() == NOT_FOUND) { throw new MyRecordNotFoundException(hcee); } }else { handleRestClientException(ex, Constants.MYAPP); } ...
throw new RestClientException("Unknown status code [" + statusCode + "]"); } } 可見,4xx的狀態嗎會拋出HttpClientErrorException;5xx的狀態碼會拋出HttpServerErrorException。這也就是我們一開始遇到的問題的原因所在瞭。而在handleError中,執行瞭response.getBody(),這就導致我們後續獲取不到響應體瞭,如果要...
根据我的经验,在调用 SpringRestTemplate#exchange随后收到“404 - Not Found”响应后,RestClientException会抛出 a 而不是返回ResponseEntity可以检查其状态的 a (即: withResponseEntity#getStatusCode#is4xxClientError)。 我不明白为什么HttpStatus#is4xxClientError即使存在,如果反而Exception抛出一个阻止返回ResponseEntity...

According to the reference documentation, the RestClient introduced in Spring 6 "throws a subclass of RestClientException when retrieving a response with a 4xx or 5xx status code". The API documentation of RestClientException currently only mentions RestTemplate, it would be helpful if there was a...
