GraalVM • Platform developed by Oracle • Polyglot VM ◦
JVM-based languages (Java, Scala, Kotlin! …) ◦ JavaScript, Python, Ruby, R ◦ LLVM-based languages (C, C++, ...) • AOT Compiler ◦ Java code is compiled to native code • Community Edition / Enterprise Edition
$ docker run --rm findepi/graalvm java -version openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-11) GraalVM 1.0.0-rc2 (build25.71-b01-internal-jvmci -0.43, mixed mode)
Familiar Spring Boot application @SpringBootApplication class DemoApplication fun main(args: Array<String>)
{ runApplication<DemoApplication>(*args) } @Service class HelloService { fun hello(): String = "Hello, world!" } @RestController class HelloController(val helloService: HelloService) { @GetMapping("") fun hello(): String = helloService.hello() }
$ ./gradlew bootRun $ curl http://localhost:8080 Hello, world! Spring app
written in Kotlin runs on GraalVM
$ ./gradlew assemble $ native-image -jar\ build/libs/demo-0.0.1-SNAPSHOT.jar Native
$ ./gradlew assemble $ native-image -jar\ build/libs/demo-0.0.1-SNAPSHOT.jar Error: com.oracle.graal.pointsto.constraints.Un supportedFeatureException:

Spring Fu • Micro-framework for Kotlin • Like Spring 5
functional registration
Hello, Spring Fu class HelloService { fun hello(): String =
"Hello, world!" } class HelloController(val helloService: HelloService) { fun hello(request: ServerRequest): Mono<ServerResponse> { val hello = helloService.hello() return ServerResponse.ok().syncBody(hello) } }
Hello, Spring Fu fun main(args: Array<String>) = application { bean<HelloService>()
bean<HelloController>() webflux { server(netty(8080)) { routes { this.context =
[email protected]
val helloController = ref<HelloController>() GET("/", helloController::hello) } } } }.run(await = true)
Hello, Spring Fu fun main(args: Array<String>) = application { bean<HelloService>()
