我浏览了所有的答案，如果你需要设置认证类型或连接超时，那么你可以这样做:

SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
factory.setConnectTimeout(Integer.valueOf(YOUR_VALUE));
factory.setReadTimeout(Integer.valueOf(YOUR_VALUE));

RestTemplate restTemplate = new RestTemplate(new BufferingClientHttpRequestFactory(factory));
restTemplate.getInterceptors().add(new LoggingRequestInterceptor());
restTemplate.getInterceptors().add(new BasicAuthenticationInterceptor(USER_NAME,PASSWORD,StandardCharsets.UTF_8));
return restTemplate;

application.properties

logging.level.org.springframework.web.client=DEBUG

application.yml

logging:
  level:  
    root: WARN
    org.springframework.web.client: DEBUG

除了上面的讨论，这只代表了快乐的场景。如果出现错误，您可能无法记录响应。

在这种情况下加上上面所有的情况，您必须重写DefaultResponseErrorHandler并像下面那样设置它

restTemplate.setErrorHandler(new DefaultResponseErrorHandlerImpl());

我终于找到了正确的方法。 大部分的解决方案来自 我如何配置Spring和SLF4J以获得日志记录?

看来有两件事需要做:

在log4j中添加以下行。属性:log4j.logger.httpclient.wire=DEBUG 确保spring不会忽略您的日志配置

第二个问题主要发生在使用slf4j的spring环境中(就像我的例子一样)。 因此，当使用slf4j时，请确保发生以下两件事:

There is no commons-logging library in your classpath : this can be done by adding the exclusion descriptors in your pom : <exclusions><exclusion> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </exclusion> </exclusions> The log4j.properties file is stored somewhere in the classpath where spring can find/see it. If you have problems with this, a last resort solution would be to put the log4j.properties file in the default package (not a good practice but just to see that things work as you expect)

正如在其他响应中所述，需要对响应体进行特殊处理，以便能够重复读取它(默认情况下，在第一次读取时使用其内容)。

在设置请求时，拦截器本身不使用BufferingClientHttpRequestFactory，而是可以包装响应，并确保内容被保留，并且可以重复读取(由记录器和响应的消费者):

我的拦截器

使用包装器缓冲响应体 更紧凑的方式 记录状态码标识符(例如201创建) 包含一个请求序列号，可以方便地将并发日志条目与多个线程区分开来

代码:

public class LoggingInterceptor implements ClientHttpRequestInterceptor {

    private final Logger log = LoggerFactory.getLogger(getClass());
    private AtomicInteger requestNumberSequence = new AtomicInteger(0);

    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
        int requestNumber = requestNumberSequence.incrementAndGet();
        logRequest(requestNumber, request, body);
        ClientHttpResponse response = execution.execute(request, body);
        response = new BufferedClientHttpResponse(response);
        logResponse(requestNumber, response);
        return response;
    }

    private void logRequest(int requestNumber, HttpRequest request, byte[] body) {
        if (log.isDebugEnabled()) {
            String prefix = requestNumber + " > ";
            log.debug("{} Request: {} {}", prefix, request.getMethod(), request.getURI());
            log.debug("{} Headers: {}", prefix, request.getHeaders());
            if (body.length > 0) {
                log.debug("{} Body: \n{}", prefix, new String(body, StandardCharsets.UTF_8));
            }
        }
    }

    private void logResponse(int requestNumber, ClientHttpResponse response) throws IOException {
        if (log.isDebugEnabled()) {
            String prefix = requestNumber + " < ";
            log.debug("{} Response: {} {} {}", prefix, response.getStatusCode(), response.getStatusCode().name(), response.getStatusText());
            log.debug("{} Headers: {}", prefix, response.getHeaders());
            String body = StreamUtils.copyToString(response.getBody(), StandardCharsets.UTF_8);
            if (body.length() > 0) {
                log.debug("{} Body: \n{}", prefix, body);
            }
        }
    }

    /**
     * Wrapper around ClientHttpResponse, buffers the body so it can be read repeatedly (for logging & consuming the result).
     */
    private static class BufferedClientHttpResponse implements ClientHttpResponse {

        private final ClientHttpResponse response;
        private byte[] body;

        public BufferedClientHttpResponse(ClientHttpResponse response) {
            this.response = response;
        }

        @Override
        public HttpStatus getStatusCode() throws IOException {
            return response.getStatusCode();
        }

        @Override
        public int getRawStatusCode() throws IOException {
            return response.getRawStatusCode();
        }

        @Override
        public String getStatusText() throws IOException {
            return response.getStatusText();
        }

        @Override
        public void close() {
            response.close();
        }

        @Override
        public InputStream getBody() throws IOException {
            if (body == null) {
                body = StreamUtils.copyToByteArray(response.getBody());
            }
            return new ByteArrayInputStream(body);
        }

        @Override
        public HttpHeaders getHeaders() {
            return response.getHeaders();
        }
    }
}

配置:

 @Bean
    public RestTemplateBuilder restTemplateBuilder() {
        return new RestTemplateBuilder()
                .additionalInterceptors(Collections.singletonList(new LoggingInterceptor()));
    }
