java - 使用 OAuth2RestTemplate 在 Rest Api 调用中出现异常或错误后继续

Question

我正在使用 Spring Oauth2RestTemplate 进行休息通话。我试图在尝试进行restAPI调用并继续异常流程时捕获任何异常。

我尝试了两种方式：
方式 I（使用 try catch）。

public ResponseEntity<Object> getResponse(URI uri, HttpHeaders httpHeaders,
            Object obj) {

    ResponseEntity<Object> response = null;
    try {
        response = restTemplate.exchange(uri, HttpMethod.POST, new HttpEntity<>(obj, httpHeaders),
                Object.class);

    } catch (Exception serverEx) {
        LOGGER.error("ERROR while calling API.Full Exception: ",serverEx);
        response.getBody().setLink(object.getUrl());
    }

    return response;
}

方式二（海关处理）。

public class RestTemplateResponseErrorHandler implements ResponseErrorHandler {

 private static final Logger LOGGER = LogManager.getLogger(RestTemplateResponseErrorHandler.class);

@Override
public boolean hasError(ClientHttpResponse httpResponse) throws IOException {
    return (httpResponse.getStatusCode().series() == Series.CLIENT_ERROR
            || httpResponse.getStatusCode().series() == Series.SERVER_ERROR);
}

@Override
public void handleError(ClientHttpResponse httpResponse) {
    //Log The Error but contibue the flow
}
}

但无论哪种方式执行都不会停止。我想继续执行流程。如果呼叫失败，我想处理它并继续流程。有人可以建议这里发生了什么吗？

例外：

错误响应 OutboundJaxrsResponse{status=500, reason=Internal Server Error, hasEntity=true, closed=false, buffered=false}

请问对此有什么建议吗？
