Kotlin + SpringBoot 2.0.0-M4がtu loadアプリケーションコンテキスト（BeanCreationException）に失敗しました

私はKotlinとSpring（SpringBoot経由）で作業しています。私は2.0.0-M3だったし、すべてが正しかった。Kotlin + SpringBoot 2.0.0-M4がtu loadアプリケーションコンテキスト（BeanCreationException）に失敗しました

私はM4にジャンプすることに決めました。その後、私はいくつかの問題を抱えていた。

私は、次のスタックトレースを得た：ここ

ありがとう私は一見するつもりです。 –

このStackOverflowの質問からreproプロジェクトを作成しましたが、そのような例外は発生しましたが、stacktraceはKotlin APIを直接呼び出しているSpring Data Commonsレベルにあるようですので、この問題をhttps：//jira.springに移動しました。 io/browse/DATACMNS-1170の場合、Spring Dataチームが処理します。 –

こんにちは@SébastienDeleuze！コミットメントありがとう、私は本当に謝る！ – romainbsl

に同じ問題があります。デフォルトの引数なしコンストラクタを除くEntityクラスのコンストラクタをすべて削除します。その問題を解決する

Thx。それは解決策ですが、コンストラクタは必要ないかもしれません。そのような場合は、将来必要としないことではありません。私はあなたの答えを検証する数日前に待つでしょう。 – romainbsl
