原因

  • 根本的な原因は不明

対応

  • ROOTのログレベルがDEBUGになっていたので、INFOにしてあげる
application.yml
spring:
  profiles:
    active: development

server:
  port: 8080

---

# Development
spring:
  profiles: development
logging:
  level:
    #root: DEBUG
    root: INFO

全部DEBUGレベルでエラー出力されていたので、当然出力されなくなる

コンソールログがスッキリする。

その他

java.lang.ClassNotFoundException: org/springframework/context/support/LiveBeansViewでググって紹介されていた対応の中で、SpringBootの起動設定にあるjmxを無効化（チェックボックス外す）すると発生しなくなるとか、
gradleやmavenの .m2,.gradleを削除してリフレッシュすると発生しなくなるとか、
書かれていたんですが、私の場合、試してみてもだめでした。

所感

  • エラーが出力されるのは気持ちが悪けど、そもそもrootをDEBUGで運用することはないかな、どうだろう。
