What are the differences between ExchangeStrategies and wiretap for WebClient logging?

Question

I am working with Spring WebClient and exploring ways to enable detailed logging for debugging purposes. Specifically, I am looking at two approaches: ExchangeStrategies and wiretap. Below are the details of my configuration:

1. Using wiretap for logging.

   I have configured the WebClient to use Netty's wiretap feature to log network-level data for HTTP requests and responses:

   HttpClient httpClient = HttpClient.create()
   .wiretap("reactor.netty.http.client.HttpClient", LogLevel.DEBUG, AdvancedByteBufFormat.TEXTUAL);
   
   WebClient webClient = WebClient.builder()
   .clientConnector(new ReactorClientHttpConnector(httpClient))
   .build();
   

   This logs details such as headers, request body, response body, and HTTP status codes at the network level.

2. Using ExchangeStrategies for logging.

   Additionally, I enabled logging for the serialization/deserialization process by customizing the ExchangeStrategies:

   ExchangeStrategies strategies = ExchangeStrategies.builder()
       .codecs(configurer -> configurer.defaultCodecs().maxInMemorySize(1024 * 1024 * 50))
       .build();
   
   strategies.messageWriters().stream()
       .filter(LoggingCodecSupport.class::isInstance)
       .forEach(writer -> ((LoggingCodecSupport) writer).setEnableLoggingRequestDetails(true));
   

   This approach focuses on logging details during the transformation of request and response bodies into objects.

My questions:

1. What are the functional differences between ExchangeStrategies and wiretap for debugging purposes in WebClient?
2. Are there scenarios where one method is preferred over the other?
3. How can I ensure that both the serialization/deserialization process and network-level data are logged in detail?
