To add to the sibling comments, you'll also enjoy the monster amount of introspection made available in the combination of the JVM and JMX exposed via the Spring actuator endpoints. We regularly adjust logging levels of running pods in order to sniff out errant behavior versus bouncing them to fiddle with some log level. I have yet to play with a software stack that is designed for as much in-flight tuning as Spring on the JVM Don't overlook @ConfigurationProperties <https://docs.spring.io/spring-boot/docs/3.1.1/reference/html/features.html#features.external-config.typesafe-configuration-properties https://docs.spring.io/spring-boot/docs/3.1.1/reference/html...> as a way of strongly typing any configuration knobs that your application may require. That not only allows static typing to avoid the hazardous @Value("some.vaule.oops") but it also means that IJ will tab complete (with typechecks) in your application.{properties,json,yaml,whatever}
