could not deserialize
他のテーブルと同じようにJpaRepositoryを作成していて、findAll()を読んだらエラーが出ました。

解決策調べてソースとDB構成確認しましたが、エラーは変わらず。
【解決】importのパッケージがここだけ違ってた
とても単純なことに、このrepositoryで使用しているentityだけ、Timestampカラムでimportしているパッケージが間違っていました。
だから一致しなくてdeserealizeできなかったのか。。
（誤）import java.security.Timestamp; （正）import java.sql.Timestamp;
ここを直したら、修正完了！
この問題は本当に単純なimport間違いなので、焦る前にソースの確認で一発解決でした。問題に気が付きにくい理由は、importが間違っているというエラーが出ないこと。IDAはショートかっと1つで自動的に適切なパッケージをimportしてくれます。同名クラスが他パッケージで存在する場合は、想定外のクラスがimportされてしまうことが多々あるので、変更を加えた箇所は本当に全て間違いがないか、エラーが出ていなくても確認しましょう！
