在Apache HttpClient的帮助下登录Logback:

在类路径中需要Apache HttpClient:

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.5.10</version>
</dependency>

配置您的RestTemplate以使用HttpClient:

restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

要记录请求和响应，请添加到Logback配置文件:

<logger name="org.apache.http.wire" level="DEBUG"/>

或者记录更多:

<logger name="org.apache.http" level="DEBUG"/>

所给出的溶液由异种杀菌剂使用

logging.level.org.apache.http=DEBUG

是好的，但问题是默认情况下Apache HttpComponents是不使用的。

要使用Apache，将HttpComponents添加到pom.xml中

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpasyncclient</artifactId>
</dependency>

然后配置RestTemplate:

RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(new HttpComponentsAsyncClientHttpRequestFactory());

您可以使用spring-rest-template-logger来记录RestTemplate HTTP流量。

在Maven项目中添加一个依赖项:

<dependency>
    <groupId>org.hobsoft.spring</groupId>
    <artifactId>spring-rest-template-logger</artifactId>
    <version>2.0.0</version>
</dependency>

然后自定义你的RestTemplate，如下所示:

RestTemplate restTemplate = new RestTemplateBuilder()
    .customizers(new LoggingCustomizer())
    .build()

确保在application.properties中启用了调试日志记录:

logging.level.org.hobsoft.spring.resttemplatelogger.LoggingCustomizer = DEBUG

现在所有的RestTemplate HTTP流量将被记录到调试级别的org.hobsoft.spring.resttemplatelogger.LoggingCustomizer。

免责声明:这个库是我写的。

这些答案都不能完全解决问题。Mjj1409实现了大部分功能，但方便地避免了记录响应的问题，因为这需要更多的工作。Paul Sabou提供了一个看似现实的解决方案，但没有提供足够的细节来实际实现(对我来说根本没用)。Sofiene得到了日志记录，但遇到了一个严重的问题:响应不再可读，因为输入流已经被消耗了!

我建议使用BufferingClientHttpResponseWrapper来包装响应对象，以允许多次读取响应体:

public class LoggingRequestInterceptor implements ClientHttpRequestInterceptor {

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

    @Override
    public ClientHttpResponse intercept(final HttpRequest request, final byte[] body,
            final ClientHttpRequestExecution execution) throws IOException {
        ClientHttpResponse response = execution.execute(request, body);

        response = log(request, body, response);

        return response;
    }

    private ClientHttpResponse log(final HttpRequest request, final byte[] body, final ClientHttpResponse response) {
        final ClientHttpResponse responseCopy = new BufferingClientHttpResponseWrapper(response);
        logger.debug("Method: ", request.getMethod().toString());
        logger.debug("URI: ", , request.getURI().toString());
        logger.debug("Request Body: " + new String(body));
        logger.debug("Response body: " + IOUtils.toString(responseCopy.getBody()));
        return responseCopy;
    }

}

这将不会消耗InputStream，因为响应体被加载到内存中，可以多次读取。如果你的类路径上没有BufferingClientHttpResponseWrapper，你可以在这里找到简单的实现:

https://github.com/spring-projects/spring-android/blob/master/spring-android-rest-template/src/main/java/org/springframework/http/client/BufferingClientHttpResponseWrapper.java

设置RestTemplate:

LoggingRequestInterceptor loggingInterceptor = new LoggingRequestInterceptor();
restTemplate.getInterceptors().add(loggingInterceptor);

Related to the response using ClientHttpInterceptor, I found a way of keeping the whole response without Buffering factories. Just store the response body input stream inside byte array using some utils method that will copy that array from body, but important, surround this method with try catch because it will break if response is empty (that is the cause of Resource Access Exception) and in catch just create empty byte array, and than just create anonymous inner class of ClientHttpResponse using that array and other parameters from the original response. Than you can return that new ClientHttpResponse object to the rest template execution chain and you can log response using body byte array that is previously stored. That way you will avoid consuming InputStream in the actual response and you can use Rest Template response as it is. Note, this may be dangerous if your's response is too big

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());
