使用mongodb的Spring数据进行Spring引导：加载应用程序时出错

我正在spring boot中使用mongoDB测试spring数据。
收到消息“**警告**：由于@ComponentScan的默认包，您的应用程序上下文不太可能启动。”启动应用程序时收到以下消息：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: URL [jar:file:/C:/apache-maven-       3.3.9/repo/org/springframework/boot/spring-boot-autoconfigure/1.3.5.RELEASE/spring-boot-autoconfigure-1.3.5.RELEASE.jar!/org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$JdbcTemplateConfiguration.class]; nested exception is java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$JdbcTemplateConfiguration due to org/springframework/jdbc/core/ConnectionCallback not found. Make sure your own configuration does not rely on that class. This can also happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

问题是什么？

问题是主类（将实现“CommandLineRunner”的类）应该在特定的包中，而不是在默认包中。其他DAO也应处于相同或子级别。现在我可以更新和查看monogoDB的数据了。问题是主类（将实现“CommandLineRunner”）应该在特定的包中，而不是在默认包中。其他DAO也应处于相同或子级别。现在我可以更新和查看monogoDB的数据了，我发现了问题所在。问题是主类（将实现“CommandLineRunner”的类）应该在特定的包中，而不是在默认包中。其他DAO也应处于相同或子级别。现在我可以更新和查看monogoDB的数据。你可以回答你的问题。我发现了问题。问题是主类（将实现“CommandLineRunner”的类）应该在特定的包中，而不是在默认包中。其他DAO也应处于相同或子级别。现在我可以更新和查看monogoDB的数据了。你可以回答你的问题了。
