springapp-servlet.xmlから値を設定しようとしていますが、エラーメッセージが表示されてプロパティを設定できません。
タイプ[java.lang.String]のプロパティ値をプロパティ'productManager'に必要なタイプ[ProductManager]に変換できませんでした。ネストされた例外はjava.lang.IllegalArgumentExceptionです：タイプ[java.lang.String]の値をプロパティ'productManager'に必要なタイプ[ProductManager]に変換できません：一致するエディターまたは変換戦略が見つかりません
