Spring-boot, tomcat-embedded — how define catalina.properties?

Question

When running spring-boot with tomcat-embedded, how do I set/change these tomcat-config system-properties?

I tried just adding -D... on the commandline, but doesnt seem to work.

you may have a look at common application properties & Embedded servlet containers — Amit Phaltankar
your 1st links provides, I guess, spring-equivalents for a few of the tomcat system-properties above, but there are many more in the tomcat-doc... your 2nd link -- hard to digest I think.... there is no simple way to just set the tomcat-doc properties when running embedded? or an example/link how to use configurators, etc, if required to achieve it, would be helpful. — Rop
The 2nd link should be: docs.spring.io/spring-boot/docs/current/reference/htmlsingle/… — Peter Wippermann

I am currently defining one of the catalina.properties via command line when starting my spring-boot application.

The property we are adding is: tomcat.util.http.parser.HttpParser.requestTargetAllow

The complete command I use to run the application is:

mvn -Dtomcat.util.http.parser.HttpParser.requestTargetAllow={} spring-boot:run

You should be able to append more catalina properties as follows:

mvn -Dtomcat.util.buf.StringCache.byte.enabled=true -Dtomcat.util.http.parser.HttpParser.requestTargetAllow={} spring-boot:run

I ended up with this solution with the help of following posts:

Let me know if it works for you.
