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());

用一些代码扩展@hstoerr answer:

创建LoggingRequestInterceptor来记录请求响应

public class LoggingRequestInterceptor implements ClientHttpRequestInterceptor {

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

    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {

        ClientHttpResponse response = execution.execute(request, body);

        log(request,body,response);

        return response;
    }

    private void log(HttpRequest request, byte[] body, ClientHttpResponse response) throws IOException {
        //do logging
    }
}

设置创建RestTemplate

RestTemplate rt = new RestTemplate();

//set interceptors/requestFactory
ClientHttpRequestInterceptor ri = new LoggingRequestInterceptor();
List<ClientHttpRequestInterceptor> ris = new ArrayList<ClientHttpRequestInterceptor>();
ris.add(ri);
rt.setInterceptors(ris);
rt.setRequestFactory(new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory());

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)

在Spring Boot中，您可以通过在属性中设置这个(或其他12因素方法)来获得完整的请求/响应。

logging.level.org.apache.http=DEBUG

这个输出

或者只是loginging.level.org.apache.http.wire =DEBUG，它似乎包含了所有相关信息

我的日志记录器配置使用XML

<logger name="org.springframework.web.client.RestTemplate">
    <level value="trace"/>
</logger>

然后你会得到如下内容:

DEBUG org.springframework.web.client.HttpMessageConverterExtractor.extractData(HttpMessageConverterExtractor.java:92) : Reading [com.test.java.MyClass] as "application/json" using [org.springframework.http.converter.json.MappingJackson2HttpMessageConverter@604525f1]

通过HttpMessageConverterExtractor.java:92，你需要继续调试，在我的情况下，我得到了这个:

genericMessageConverter.write(requestBody, requestBodyType, requestContentType, httpRequest);

这:

outputMessage.getBody().flush();

outputMessage.getBody()包含http(post类型)发送的消息

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);
