Spring Webflux Reactor Netty：HTTP请求/响应十六进制转储？

Question

What log level we have to set in application.properties in order to see the full HTTP request and response with headers and body as a hex dump in the console from reactor-netty?

logging.level.reactor.netty=trace

Only shows response http headers.

HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
Content-Length: 248
Cache-Control: no-cache, no-store, max-age=0, must-revalidate

Answer 1

Keep the logging level as DEBUG or TRACE and follow the instructions below:

1. If you want to see the hex dump for the server then you can customise it like this:

@Component
public class MyNettyWebServerCustomizer
        implements WebServerFactoryCustomizer<NettyReactiveWebServerFactory> {
    @Override
    public void customize(NettyReactiveWebServerFactory factory) {
        factory.addServerCustomizers(httpServer -> httpServer.wiretap(true));
    }
}

2. If you want to see the hex dump for the client then you can customise it like this:

WebClient.builder()
        .clientConnector(new ReactorClientHttpConnector(HttpClient.create().wiretap(true)))
        .build();
