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);

wire提供了太多不可读的日志，所以我使用日志记录应用程序Servlet和RestTemplate请求和响应的有效负载。

build.gradle:

compile group: 'org.zalando', name: 'logbook-spring-boot-starter', version: '2.6.2'

或Maven依赖:

<dependency>
    <groupId>org.zalando</groupId>
    <artifactId>logbook-spring-boot-starter</artifactId>
    <version>2.6.2</version>
</dependency>

应用程序。属性(或槽YAML):

logging.level.org.zalando.logbook = TRACE

RestTemplate.java:

import java.util.function.Supplier;

import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.ClientHttpRequestFactory;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
import org.zalando.logbook.httpclient.LogbookHttpRequestInterceptor;
import org.zalando.logbook.httpclient.LogbookHttpResponseInterceptor;

@Configuration
public class RestTemplateConfiguration {
    private final LogbookHttpRequestInterceptor logbookHttpRequestInterceptor;
    private final LogbookHttpResponseInterceptor logbookHttpResponseInterceptor;

    public RestTemplateConfiguration(LogbookHttpRequestInterceptor logbookHttpRequestInterceptor,
            LogbookHttpResponseInterceptor logbookHttpResponseInterceptor) {
        this.logbookHttpRequestInterceptor = logbookHttpRequestInterceptor;
        this.logbookHttpResponseInterceptor = logbookHttpResponseInterceptor;
    }

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) {
        return restTemplateBuilder
                .requestFactory(new MyRequestFactorySupplier())
                .build();
    }

    class MyRequestFactorySupplier implements Supplier<ClientHttpRequestFactory> {
        @Override
        public ClientHttpRequestFactory get() {
            // Using Apache HTTP client
            CloseableHttpClient client = HttpClientBuilder.create()
                    .addInterceptorFirst(logbookHttpRequestInterceptor)
                    .addInterceptorFirst(logbookHttpResponseInterceptor)
                    .build();
            return new HttpComponentsClientHttpRequestFactory(client);
        }
    }
}

设置RestTemplate:

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

假设RestTemplate配置为使用HttpClient 4。x，你可以在这里阅读HttpClient的日志文档。这些记录器与其他答案中指定的记录器不同。

HttpClient 3的日志配置。X在这里可用。

解决这个问题的简单方法是:

使用RestTemplateBuilder创建RestTemplate的Bean:它可以让您更好地控制连接时间和读取时间。

@Configuration
public class RestTemplateConfig {
  @Bean
  public RestTemplate restTemplate(RestTemplateBuilder builder) {
    return builder
      .setConnectTimeout(Duration.ofMillis(60000))
      .setReadTimeout(Duration.ofMillis(60000))
      .build();
  }

}

将这一行添加到资源/应用程序中。属性文件: logging.level.org.springframework.web.client.RestTemplate =调试 希望问题能得到解决!

So many responses here require coding changes and customized classes and it really is not necessary. Gte a debugging proxy such as fiddler and set your java environment to use the proxy on the command line (-Dhttp.proxyHost and -Dhttp.proxyPort) then run fiddler and you can see the requests and responses in their entirety. Also comes with many ancillary advantages such as the ability to tinker with the results and responses before and after they are sent to run experiments before committing to modification of the server.

可能出现的最后一个问题是，如果必须使用HTTPS，则需要从fiddler导出SSL证书并将其导入java密钥存储库(cacerts)提示:默认的java密钥存储库密码通常是“changeit”。
