Spring Boot has a modules called Actuator, which provides HTTP request logging out of the box.

https://docs.spring.io/spring-boot/docs/current/reference/html/actuator.html#actuator.endpoints

나는 CommonsRequestLoggingFilter 사용

스프링부트 사용 예시

server:
  port: 8080
  servlet:
    context-path: /
    encoding:
      charset: utf-8
      enabled: true

logging:
  level:
    "[org.springframework.web.filter.CommonsRequestLoggingFilter]": debug
spring:
  servlet:
    multipart:
      max-file-size: 10MB

@Configuration
public class RequestLoggingFilterConfig {

    @Bean
    public CommonsRequestLoggingFilter logFilter() {
        CommonsRequestLoggingFilter filter
                = new CommonsRequestLoggingFilter();
        filter.setIncludeQueryString(true);
        filter.setIncludePayload(true);

        filter.setMaxPayloadLength(640000);
        filter.setIncludeHeaders(true);
        filter.setIncludeClientInfo(true);
        filter.setAfterMessagePrefix("REQUEST DATA : ");
        return filter;
    }
}

@GetMapping("/send")
    public void sendMultipart() throws Exception {
        String filePath = "C:\\Users\\songn\\Downloads\\Telegram Desktop\\unirest.png";

        Map<String, Object> params = new HashMap<String, Object>();

        params.put("id", "AIBAA");                                              

        File file = new File(filePath);

        logger.info("file: " + file);

        
        HttpResponse<String> response = Unirest.post("http://localhost:8080/resp")
                .queryString(params)
                .field("img", new File(filePath))
                .asString();
        
//헤더는 자동 multipart-form data

        String responseJson = response.getBody();
        logger.info("## CrescomAiService.insUpload() responseJson={}", responseJson);

    }

    @PostMapping(value = "/resp",  consumes = {MediaType.MULTIPART_FORM_DATA_VALUE})
    public String respMultipart(@RequestParam("img") MultipartFile img, HttpServletRequest req){
        logger.info("multipartFile: " + img );

        //logger.info("req: " + req.toString());

        String id = req.getParameter("id");

        // img.getBytes()  바이트로 변환해서 파일 저장하면 될것 같습니다.

        logger.info("id: "+ id);

        return "ok";
    }

요런식으로 로깅 확인.. 프론트엔드 개발자는 axios의 interceptor 이용해서 로깅 찍는 거랑 비슷하게 생각하면 됨.
