Spring JPA MVC環境でMySqlデータベースに接続しようとしていて、次の問題を解決できません。com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorExceptionの不明な列
1）エンティティ・クラスで正しい列マッピングを使用してJPAリポジトリを介してデータをフェッチしようとしていますが、依然として間違った列名を宣言しています。
2）SQL Serverへの接続を変更するには、ドライバを変更するだけですか？それとも何か他のものが必要ですか？
私のプロジェクトは以下の通りです。オーバーキルが、everthingのビットがここにあります:)参考まで
