Kotlinのログ出力方法

Kotlin

Last updated at 2019-01-09Posted at 2019-01-09

以下のおまじない（２行）を入れて、logger.info("ログ出力")で出力。

import org.slf4j.LoggerFactory
private val logger = LoggerFactory.getLogger(javaClass)

例：

import org.slf4j.LoggerFactory

@Component
class YourClass {
    private val logger = LoggerFactory.getLogger(javaClass)
    public fun yourFunction(): Any? {
        logger.info("ログ出力")
        return null
    }
}

出力結果：

2019-01-09 11:31:14.400  INFO 21313 --- [xxx] xxx.YourClass : ログ出力
