spring batch 5.x 버전 설정

@SpringBootApplication
class SpringBatchTutorialApplication

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

@EnableBatchProcessing 은 3.x 부터 사용하지 않습니다.

        .build()

    @StepScope
    @Bean
    fun helloWorldTasklet(): Tasklet = Tasklet { contribution, context ->
        println("Hello, World from Kotlin Tasklet!")
        println("Hello, World from Kotlin Tasklet!")
        println("Hello, World from Kotlin Tasklet!")
        RepeatStatus.FINISHED
    }

}

program arguments 설정하고 실행하면 잘 될겁니다.
