I also ditched Spring the day I started using Kotlin Feels like a lot of the Spring stuff exists to make Java dev easier and it only adds weight to a Kotlin project that s my personal opinion Now I m using a combination of VertX with my own extension functions no more 20MB Spring jars

< janvladimirmostert> don t worry you re not the only one After being presented back in the day to fix a spring project containing really 275 XML files with multiple layers of XML inheritance I vowed never again Now our services are typically between 10 25meg in size and start up in an instant instead of seconds We did fix the project btw and deleted every single last XML file grinning

That s my experience as well project starts up in 100ms instead of 5 10 seconds when spring is doing annotation scanning and who knows what

janvladimirmostert · Answer

Spring without XML configuration in my opinion is even more verbose when you have to start stacking countless annotations on top of countless other annotations some classes had 7 annotations on them in the Spring days Testing is also a pain since you need to inject the Spring Context which then takes ages before the test can start

5 10 seconds That s not so bad one of my Spring projects need up to a minute to start slightly smiling face

The reason I have a JRebel license is because I have to maintain some legacy Spring3 + Hibernate + Java projects that also takes around 50 60 seconds to start In Kotlin without Spring the benefits of JRebel doesn t seem to justify the cost anymore since it restarts so quickly
