【Spring Boot：対処中】詰まったこと(spring.resources.cache-period)
こんにちは。
今日は、Spring Bootの学習をしていく上で詰まっていることをメモ的に残しておきます。（解決したら更新を行います）
今回起こっている問題
静的ファイルのキャッシュ設定をした際にエラーが発生
今回は静的ファイルのキャッシュ設定をしようとした際に詰まっていることです。
Spring Bootでは静的ファイルのキャッシュ設定はデフォルトでは行われないため、
spring.resources.cache-periodで設定を行うことができます。
そこで設定をしようとしたところ、以下エラーログのようなエラーが起こって起動しなくなりました。
