私は本当にここで助けが必要です.. 私はsimple webapps springbootをweb、postgresql、jdbc、vaadinで作成しようとしました。 アプリを起動すると、アプリは起動せず、例外がスローされます。 "JdbcTemplate型の修飾Beanはありません"という例外があります。 アーティファクトspring-boot-starter-jdbcを追加するには、stackoverflowのいくつかの提案が、私のPOMはすでにそれを行い、まだ動作しません。私の設定以下はフィールド 'jdbcTemplate'で表現されている満足していない依存関係
のsrc /メイン/リソース/ application.properties：
spring.datasource.url=jdbc:postgresql://localhost:5432/sehati
spring.datasource.username=sehati
spring.datasource.password=password

そしてまた、私はH2データベースを使用しようとしました。私のアプリケーションは起動することができますが、データソース接続はspring-boot-jdbc（url='jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=false', username='sa'）の設定済みデータソースを常に使用しているようですが、すでにapplication.propertiesに新しいものが記述されています。
誰かが私のプロジェクトに間違いを見つけることができますか？ 本当にありがとうございます。
ありがとうございます。この時点で私の推測では、あなたのシステムに2つの 'DataSource'があるということです。 'application.properties'の設定は、あなたのために' DataSource'ビーンを作成することを確実にします。自分でデータソースを作成している可能性はありますか？ "--debug"でアプリケーションを実行すると、JdbcTemplateAutoConfigurationが有効になっていない理由を説明するレポートが表示されます。 –
こんにちは@ステファン。手掛かりありがとうございます。私は、application.propertiesに1つのDatasourceしか設定されておらず、AFAIKは他のデータソースが作成されていません。私の完全なEclipseプロジェクトは[ここ]（https://www.dropbox.com/s/wgee2bgoc9hkrx8/siapotek.tar.gz?dl=0）にアクセスできます。親切に私のプロジェクトを見直してください。 – Midoen
私はまた、プロジェクトをデバッグしようとするが、私はEclipseの[コンソール]（https://www.dropbox.com/s/q0ztkqme89tzukv/console.out?dl=0）にスローされた例外はない。 1つの出力行は私に不思議に思う、それは "スキップされた（空の）設定ファイル..."、私はすでにデータソースの設定を含むapplication.propertiesをチェックした – Midoen
