Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest

@springbootTest
問題発生
今日、rabbitmqのメッセージ確認メカニズム(confirm)を作成し、springbootTest注釈を使用してテストを行い、以下の問題が発生しました.

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

問題の原因springbootTestはイニシエータクラスにロードされていません.
解決策を@SpringBootTest(classes=ConfirmApplication.class)に変更
これでプログラムが正常に動作します.以上の内容が皆さんに役に立つことを願っています.
