MySpringApplication 코틀린 변환 코드입니다.

import org.springframework.boot.web.servlet.ServletContextInitializer
import org.springframework.boot.web.servlet.server.ServletWebServerFactory
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext
import org.springframework.web.servlet.DispatcherServlet
import kotlin.reflect.KClass

class MySpringApplication(
) {
    companion object {
        fun run(
            applicationClass: KClass<*>,
            args: Array<String>,
        ) {

            val applicationContext = AnnotationConfigWebApplicationContext()
            applicationContext.register(applicationClass.java)
            applicationContext.refresh()

            val serverFactory = applicationContext.getBean(ServletWebServerFactory::class.java)
            val dispatcherServlet = applicationContext.getBean(DispatcherServlet::class.java)

            val webServer = serverFactory.getWebServer(ServletContextInitializer {
                it.addServlet("dispatcherServlet", DispatcherServlet(applicationContext)).addMapping("/*")
            })

            webServer.start()
        }
    }
}

import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.ComponentScan
import org.springframework.context.annotation.Configuration
import org.springframework.web.servlet.DispatcherServlet


@Configuration
@ComponentScan
class DeepApplication {

    @Bean
    fun servletWebServerFactory() = TomcatServletWebServerFactory()

    @Bean
    fun dispatcherServlet() = DispatcherServlet()
}

fun main(args: Array<String>) {
    MySpringApplication.run(DeepApplication::class, args)
}

예제 코드를 코틀린으로 변환했습니다.

마지막 코드는 부트 처음 생성 시 코드로 되돌아가면 됩니다.

fun main(args: Array<String>) {
    runApplication<DeepApplication>(*args)
}
