Question

服务器响应为HTTP 400错误请求，其中包含详细信息，但仅客户端日志：

java.io.IOException: Server returned HTTP response code: 400 for URL:
                     http://localhost:7101/test?param=1

我想记录有关我可以从HttpClientErrorException获取的错误的详细信息：

httpEx.getCause();
httpEx.getResponseBodyAsString();
httpEx.getResponseHeaders();
httpEx.getStatusCode();
httpEx.getStatusText()

我也设置了处理程序，但是它仅捕获正HTTP编码，例如HTTP 200。在其他情况下，它无法处理错误。

Java 1.7 春天3.2.18

代码：

restTemplate is class org.springframework.web.client.RestTemplate 

[...]
try {
    HttpEntity request = new HttpEntity(createHeaders(userName, userPassword));
    restTemplate.setErrorHandler(new MyResponseErrorHandler());

    ResponseEntity<ResponseMessage> response = 
        restTemplate.exchange(resource, 
                              HttpMethod.GET, 
                              request, 
                              ResponseMessage.class);
    ResponsePaymentsMessage obj = response.getBody();
} catch (HttpClientErrorException httpEx) {
    if (httpEx.getStatusCode().equals(HttpStatus.NOT_FOUND)) {
        throw new NotFoundException("Not found exception " + resource);
    }
    [...]
}

错误处理程序类：

public class MyResponseErrorHandler implements ResponseErrorHandler {

private static final Logger LOG = LoggingUtilsSlf.getInvokingClassSLFLogger();

@Override
public void handleError(ClientHttpResponse clienthttpresponse) throws IOException {

    if (clienthttpresponse.getStatusCode() == HttpStatus.FORBIDDEN) {
        LOG.debug(HttpStatus.FORBIDDEN + " response. Throwing authentication exception");
        throw new IOException();
    }
}

@Override
public boolean hasError(ClientHttpResponse clientHttpResponse) throws IOException {

    if (clientHttpResponse.getStatusCode() != HttpStatus.OK) {
        LOG.debug("Status code: " + clientHttpResponse.getStatusCode());
        LOG.debug("Response" + clientHttpResponse.getStatusText());
        LOG.debug(clientHttpResponse.getBody().toString());

        if (clientHttpResponse.getStatusCode() == HttpStatus.FORBIDDEN) {
            LOG.debug("Call returned a error 403 forbidden respone");
            return true;
        }
    }
    return false;
}

}

somone可以帮助您从restTemplate.exchange捕获HTTP响应的详细信息吗？

RestTemplate.exchange捕获IOException不是ClientHttpExceptionError
