私のアプリケーションは Spring 3 + MyBatis 3 を使用しています。複数のデータベース接続 (MySQL および Oracle) をセットアップしようとしていますが、このメッセージが表示されました。
Error creating bean with name 'MySQLService' defined in ServletContext resource [/WEB-INF/appContext-database.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'MySQLDao' of bean class [com.ekalife.MyGadget.service.MainService]: Bean property 'MySQLDao' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
私のセットアップ appContext-database.xml
