私はSpring Boot Hikari CPで複数のデータベースを実装しようとしています。私はそれが2のための2つの接続プールを持つこと、（彼らは優先順位を表すいけない）プライマリとセカンダリの命名規則を乗り越えるいけないしてください 、私は私の春のブートデータソース設定ファイルを添付していますあなたの参考のために私の要件をスプリングブートひかり複数データベース自動配線失敗
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] is defined: expected single matching bean but found 2: hikari_primary,hikari_secondary
を取得しています異なるデータベース。
