most people say their JAVA_HOME was pointing to an old version, not my case.

So maybe try to remove

.gradle

both from your project root and from

~/

I already tried from

~/

, and my project home is fresh.

Could you try with Kotlin

1.1.4-3

?

You will have to set also

freeCompilerArgs = listOf("-Xjsr305-annotations=enable")

should I change the version in build.gradle.kts?

yep

(you don't need findbug jar)

@sdeleuze same error 😞

@sdeleuze may i quote you?

So maybe try to remove Gradle both from your project root and from

~/

@nfrankel just tried that too, same error again 😞

Looks like a bug in Kotlin to me. Can you post

Post

code? Primary constructor and any

init

blocks?

You’re likely having a capturing lambda in some

init

block of

Post

, I remember there was an issue like that.

Does it look like this? https://youtrack.jetbrains.com/issue/KT-19660

Or may be this: https://youtrack.jetbrains.com/issue/KT-19933 (note there is a fixed bug in JVM, but you seem to have newer version)

I have made a DSL to run a Spring WebFlux Application in a functional way

fun main(args: Array<String>) {
    webfluxApplication(Server.NETTY) { // or TOMCAT
    
        // group routers
        routes {
            router { routerApi(ref()) }
            router(routerStatic())
        }
        router { routerHtml(ref(), ref()) }
    
        // group beans
        beans {
            bean<UserHandler>()
            bean<Baz>()  // Primary constructor injection
        }
        bean<Bar>()
    
        mustacheTemplate()
    
        profile("foo") {
            bean<Foo>()
        }
    }.run()
}

The project is here : https://github.com/tgirard12/spring-webflux-kotlin-dsl

Amazing, for standalone WebFlux apps it will be super useful!

thanks !

Is it possible to write

router(::routerStatic)

?

not currently but it's easy to add

@orangy the code is https://github.com/mixitconf/mixit @sdeleuze maintains it.

Why if I run an empty spring boot application

java  -Xmx64m -Xss256k -jar springexample-0.0.1-SNAPSHOT.jar

it takes 200mb memory? Is it possible to reduce it?

dependencies {
	compile "org.springframework.boot:spring-boot-starter-actuator:$springBootVersion"
	compile "org.springframework.boot:spring-boot-starter-web:$springBootVersion"
	compile "org.springframework.boot:spring-boot-starter-undertow:$springBootVersion"
	compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlinVersion"
	compile "org.jetbrains.kotlin:kotlin-reflect:$kotlinVersion"
	runtime "org.springframework.boot:spring-boot-devtools:$springBootVersion"
	testCompile "org.springframework.boot:spring-boot-starter-test:$springBootVersion"
}

I guess you can start by having a look to Dave Syer great blog post https://spring.io/blog/2015/12/10/spring-boot-memory-performance and lastest startup time experiment https://github.com/dsyer/spring-boot-startup-bench

I just wanted to know whether we can use @value inside constructor. Ex class ‘Test(@value(“some.property.key”) val someProperty: String)’

'Test(@value(“some.property.key”) val someProperty: String)'

Sorry for duplication

If your bean has a single constructor or has a constructor annotated with

@Autowired

, yes it should work
