2. ConditionEvaluationReport

ConditionalEvaluationReport 를 주입 받아 직접 원하는 형태로 출력하는 ApplicationRunner 빈을 하나 등록 한다.

@Bean  
fun run(report: ConditionEvaluationReport) = ApplicationRunner {  
    val count = report.conditionAndOutcomesBySource.entries  
        .filter { condition -> condition.value.isFullMatch }  
        .filter { condition -> !condition.key.contains("Jmx") }  
        .map { condition ->  
            println(condition.key)  
            condition.value.forEach { println("\t${it.outcome}") }  
            println()  
            condition  
        }  
        .count()  
    println("자동 등록된 빈은 총 $count 개!")  
}

implementation("org.springframework.boot:spring-boot-starter") 만 추가했을때 등록되는 자동 목록
