如何处理Rest Template中的无效内容类型？

Question

我正在查询REST API，以应对负面情况，我在标题中得到了200代码和一些奇怪的Content-type。因此，我无法存储响应，因为它在解析时会引发异常。

下图显示了响应的标题：

 

ResponseErrorHandler：

@Component
public class AutomationResponseErrorHandler implements ResponseErrorHandler{

    private static final Logger logger = LoggerFactory.getLogger(AutomationResponseErrorHandler.class);

    @Override
    public boolean hasError(ClientHttpResponse response) throws IOException {
        // TODO Auto-generated method stub
        return response.getStatusCode() != HttpStatus.OK;
    }

    @Override
    public void handleError(ClientHttpResponse response) throws IOException {
        logger.error("Response Error: {} {} {}", response.getStatusCode(), response.getStatusText(), response.getBody());   
    }
}

自定义RestTemplate：

@Component
public class CustomRestTemplate {

    @Autowired
    AutomationResponseErrorHandler responseErrorHandler;

    public RestTemplate getRestTemplate(boolean isHttpsRequired)
            throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException {

        // if https is not required,
        if (!isHttpsRequired) {
            return new RestTemplate();
        }

        // else below code adds key ignoring logic for https calls
        TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
        SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy)
                .build();

        SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

        CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();

        HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
        requestFactory.setHttpClient(httpClient);

        RestTemplate restTemplate = new RestTemplate(requestFactory);
        restTemplate.setErrorHandler(responseErrorHandler);

        return restTemplate;
    }
}

下面是保存响应的代码：

ResponseEntity<String> response = restTemplate.getForEntity(outBound, String.class);

以下是发生的异常：

无论内容类型是什么，我都希望保存响应正文。
