how to log Spring 5 WebClient call

Question

I\'m trying to log a request using Spring 5 WebClient. Do you have any idea how could I achieve that?

(I\'m using Spring 5 and Spring boot 2)

The code looks

Answer 1

If you don't want to log the body, then this is really easy.

Spring Boot >= 2.1.0

Add the following to application.properties:

logging.level.org.springframework.web.reactive.function.client.ExchangeFunctions=TRACE
spring.http.log-request-details=true

The second line causes headers to be included in the log.

Spring Boot < 2.1.0

Add the following to application.properties:

logging.level.org.springframework.web.reactive.function.client.ExchangeFunctions=TRACE

Instead of the second line above, you need to declare a class like this:

@Configuration
static class LoggingCodecConfig {

    @Bean
    @Order(0)
    public CodecCustomizer loggingCodecCustomizer() {
        return (configurer) -> configurer.defaultCodecs()
                .enableLoggingRequestDetails(true);
    }

}
