ドライバーインスタンスの取得に失敗しました

私はSpring（Boot）を初めて使用し、HSQLDBサーバーへのプールされたデータベース接続を取得しようとしています。

私はすでにデータベースをチェックしており、Squirrelや指定されたJDBC文字列などのツールを使用して問題なくデータベースに接続できます。

URLとdriverClassNameを設定した後、私はこれを取得しています

URLが間違っているようです。私が覚えている限り、それは次のようになります：

jdbc:hsqldb:hsql://localhost:9001/devel

また、ドライバークラス名（org.hsqldb.jdbc.JDBCDriver）。

config.setDriverClassName("org.hsqldb.jdbc.JDBCDriver");

Spring Boot 1.4を使用している場合、HikariCPを使用するときにデータソースを明示的に定義する必要はありません。 ドキュメント で述べたように。

config.addDataSourceProperty("useSSL",false);が役立つ場合があります。

documentation に従って、正しい行は

config.setJdbcUrl("jdbc:hsqldb:hsql://localhost:9001/devel");
