스케쥴러 구현 (@EnableScheduling)

참고소스: https://github.com/bkjeon1614/kotlin-example-code/tree/main/kotlin-jpa-codebase

 

• Application.kt 에 설정

  ...
  import org.springframework.scheduling.annotation.EnableScheduling
  
  @EnableScheduling // 추가
  class TestApplication {
    ...
  
    fun main(...)
  }
  

• AppHealthCheckScheduler.kt 스케쥴러 테스트용 코드 작성

    package com.bkjeon.base.v1.schedule
  
    import org.apache.http.client.methods.HttpGet
    import org.apache.http.impl.client.CloseableHttpClient
    import org.apache.http.impl.client.HttpClients
    import org.slf4j.LoggerFactory
    import org.springframework.beans.factory.annotation.Value
    import org.springframework.scheduling.annotation.Scheduled
    import org.springframework.stereotype.Component
  
    @Component
    class AppHealthCheckScheduler {
  
        @Value("\${spring.config.activate.on-profile:}")
        lateinit var env: String
  
        companion object {
            private val logger = LoggerFactory.getLogger(AppHealthCheckScheduler::class.java)
            private val httpClient: CloseableHttpClient = HttpClients.createDefault()
        }
  
        // 10 분에 1번
        @Scheduled(cron = "* 0/10 * * * *")
        fun isAppHealthCheck() {
            val httpGet = HttpGet("https://www.naver.com/")
  
            try {
                logger.info(">>>>>>>>>>>>>>>>>>>> Health Check: $env")
                httpClient.execute(httpGet)
            } catch (e: Exception) {
                logger.error(">>>>>>>>>>>>>>>>>>>> Error: $e, Env: $env")
            }
        }
  
    }
