Console Logging in Spring Boot with undertow embedded server

Question

I am trying to get access log of an embedded undertow server from spring boot > 2.0 to stdout of an container. With embedded tomcat spring properties can work, but the same does not for undertow server. I tried modifying server.undertow.accesslog.* properties and tried configuring directory to /dev/stdout but unfortunately this error out.

Any suggestions how can I redirect undertow access logs to console?

Answer 1

server.undertow.accesslog.enabled=true
server.undertow.accesslog.pattern=<PATTERN>
server.undertow.accesslog.dir=/dev
server.undertow.accesslog.prefix=stdout
server.undertow.accesslog.suffix=
server.undertow.accesslog.rotate=false

This should work for you. Please don't add empty braces for suffix like this ""
