How to set enableLoggingRequestDetails='true' in Spring Boot

For Spring Boot 2.1 and below use

logging.level.org.springframework.web=DEBUG
spring.http.log-request-details=true

For Spring Boot 2.2 and above spring.http.log-request-details has been deprecated so use

logging.level.org.springframework.web=DEBUG
spring.mvc.log-request-details=true

in your application.properties if you want to see loggingRequestDetails.

From the documentation:

Whether logging of (potentially sensitive) request details at DEBUG and TRACE level is allowed.

When using webflux and spring boot 2.3.0 the following properties can be set to log request details.

logging.level.org.springframework.web.server.adapter.HttpWebHandlerAdapter=DEBUG
spring.codec.log-request-details=true
