除了在另一个答案中描述的HttpClient日志之外，您还可以引入一个ClientHttpRequestInterceptor，它读取请求体和响应并记录它。如果其他东西也使用HttpClient，或者你想要一个自定义的日志格式，你可能需要这样做。注意:您需要给RestTemplate一个BufferingClientHttpRequestFactory，这样您就可以读取两次响应。

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);
        }
    }
}

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。

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());

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());

我还想加上这个的实现。我为所有缺少的分号感到抱歉，这是用Groovy编写的。

我需要一些比现有答案更可配置的东西。下面是一个非常敏捷的rest模板bean，它将像OP所寻找的那样记录所有内容。

自定义日志拦截器类:

import org.springframework.http.HttpRequest
import org.springframework.http.client.ClientHttpRequestExecution
import org.springframework.http.client.ClientHttpRequestInterceptor
import org.springframework.http.client.ClientHttpResponse
import org.springframework.util.StreamUtils

import java.nio.charset.Charset

class HttpLoggingInterceptor implements ClientHttpRequestInterceptor {

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

    @Override
    ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
        logRequest(request, body)
        ClientHttpResponse response = execution.execute(request, body)
        logResponse(response)
        return response
    }

    private void logRequest(HttpRequest request, byte[] body) throws IOException {
        if (log.isDebugEnabled()) {
            log.debug("===========================request begin================================================")
            log.debug("URI         : {}", request.getURI())
            log.debug("Method      : {}", request.getMethod())
            log.debug("Headers     : {}", request.getHeaders())
            log.debug("Request body: {}", new String(body, "UTF-8"))
            log.debug("==========================request end================================================")
        }
    }

    private void logResponse(ClientHttpResponse response) throws IOException {
        if (log.isDebugEnabled()) {
            log.debug("============================response begin==========================================")
            log.debug("Status code  : {}", response.getStatusCode())
            log.debug("Status text  : {}", response.getStatusText())
            log.debug("Headers      : {}", response.getHeaders())
            log.debug("Response body: {}", StreamUtils.copyToString(response.getBody(), Charset.defaultCharset()))
            log.debug("=======================response end=================================================")
        }
    }
}

Rest模板Bean定义:

@Bean(name = 'myRestTemplate')
RestTemplate myRestTemplate(RestTemplateBuilder builder) {

    RequestConfig requestConfig = RequestConfig.custom()
            .setConnectTimeout(10 * 1000) // 10 seconds
            .setSocketTimeout(300 * 1000) // 300 seconds
            .build()

    PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager()
    connectionManager.setMaxTotal(10)
    connectionManager.closeIdleConnections(5, TimeUnit.MINUTES)

    CloseableHttpClient httpClient = HttpClients.custom()
            .setConnectionManager(connectionManager)
            .setDefaultRequestConfig(requestConfig)
            .disableRedirectHandling()
            .build()

    RestTemplate restTemplate = builder
            .rootUri("https://domain.server.com")
            .basicAuthorization("username", "password")
            .requestFactory(new BufferingClientHttpRequestFactory(new HttpComponentsClientHttpRequestFactory(httpClient)))
            .interceptors(new HttpLoggingInterceptor())
            .build()

    return restTemplate
}

实现:

@Component
class RestService {

    private final RestTemplate restTemplate
    private final static Logger log = LoggerFactory.getLogger(RestService.class)

    @Autowired
    RestService(
            @Qualifier("myRestTemplate") RestTemplate restTemplate
    ) {
        this.restTemplate = restTemplate
    }

    // add specific methods to your service that access the GET and PUT methods

    private <T> T getForObject(String path, Class<T> object, Map<String, ?> params = [:]) {
        try {
            return restTemplate.getForObject(path, object, params)
        } catch (HttpClientErrorException e) {
            log.warn("Client Error (${path}): ${e.responseBodyAsString}")
        } catch (HttpServerErrorException e) {
            String msg = "Server Error (${path}): ${e.responseBodyAsString}"
            log.error(msg, e)
        } catch (RestClientException e) {
            String msg = "Error (${path})"
            log.error(msg, e)
        }
        return null
    }

    private <T> T putForObject(String path, T object) {
        try {
            HttpEntity<T> request = new HttpEntity<>(object)
            HttpEntity<T> response = restTemplate.exchange(path, HttpMethod.PUT, request, T)
            return response.getBody()
        } catch (HttpClientErrorException e) {
            log.warn("Error (${path}): ${e.responseBodyAsString}")
        } catch (HttpServerErrorException e) {
            String msg = "Error (${path}): ${e.responseBodyAsString}"
            log.error(msg, e)
        } catch (RestClientException e) {
            String msg = "Error (${path})"
            log.error(msg, e)
        }
        return null
    }
}
