以前にSpringフレームワークを作成してからデータベース接続に置き換えましたが、Beanの作成に問題があります。
展開中に以下のエラーも受け取ります。
DEFAULT=C:\Users\gopc\Documents\NetBeansProjects\HelloSpringJDBC\build\web&name=HelloSpringJDBC&contextroot=/HelloSpringJDBC&force=true GlassFish Server 3.1.2 で失敗しました 展開中にエラーが発生しました: アプリのロード中に例外が発生しました: java.lang.IllegalStateException: ContainerBase .addChild: 開始: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException: ServletContext リソース [/WEB-INF/applicationContext.xml] で定義された名前 'productManager' の Bean の作成中にエラーが発生しました: プロパティ値の設定中にエラーが発生しました; ネストされた例外は org.springframework.beans.NotWritablePropertyException: Invalid property 'productDao' of bean class [SimpleProductManager]: Bean プロパティ 'productDao' is not writable or has an invalid setter method. セッターのパラメーターの型は、ゲッターの戻り値の型と一致していますか? 詳細については、server.log を参照してください。C:\Users\gopc\Documents\NetBeansProjects\HelloSpringJDBC\nbproject\build-impl.xml:1029: モジュールがデプロイされていません。詳細については、サーバー ログを参照してください。
