SpringBoot3 RestClient 打印请求和响应日志

引入依赖

RestClient 默认 requestFactory 使用的是 JdkClientHttpRequestFactory， 没有日志功能
这里需要切换为 HttpComponentsClientHttpRequestFactory

<!-- 新版 restClient 使用-->
<dependency>
    <groupId>org.apache.httpcomponents.client5</groupId>
    <artifactId>httpclient5</artifactId>
</dependency>

配置类

这里我额外加入了 Base 认证和一个 json 的消息转换器

@Bean
public RestClient mqttApiRestClient(ObjectMapper objectMapper) {
    String auth = mqttProperties.getRest().getApiKey() + ":" + mqttProperties.getRest().getSecretKey();
    byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(StandardCharsets.UTF_8));
    String header = "Basic " + new String(encodedAuth);
    HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
    factory.setConnectTimeout(3000);
    factory.setConnectionRequestTimeout(5000);
    return RestClient.builder()
            .requestFactory(factory)
            .messageConverters(httpMessageConverters -> httpMessageConverters.add(4,
                    new MappingJackson2HttpMessageConverter(objectMapper)))
            .baseUrl(mqttProperties.getRest().getApi())
            .defaultHeader("Authorization", header)
            .build();
}
