Has anyone ever tried to run a spring boot app without the org.jetbrains.kotlin.plugin.spring plugin? My understanding is that the beans DSL removes some proxying so it might not require open classes? But I'm stuck at @SpringBootApplication because I haven't found a non-annotated equivalent.

@SpringBootApplication is meta annotated with @Configuration which has by default proxyBeanMethods = true. If you want to avoid proxies by default, you may want to use @Configuration(proxyBeanMethods = false) and @EnableAutoConfiguration for example on your application class instead.

Ah, very cool, trying that now 🙂

I shoukd probably update https://github.com/sdeleuze/spring-kotlin-functional now that Spring Fu is kind of frozen.

I will let you know if I find the time to do it.

[mbonnin]

Frozen as in "working well" or more "not moving too much"?

[sdeleuze]

Not moving too much, functional is important for the Spring team, but Spring Fu is difficult to maintain and not consistent enough with regular Boot, so we need a better way.

Gotcha 👍

The repo I shared is super super old, but I will try to update it to provide a baseline for people wanting to use Kotlin + Spring the functional way
