用於彈簧數據的彈簧引導mongodb：加載應用程序時出錯

Question

我正在使用mongoDB在spring引導中測試彈簧數據。
收到消息「** WARNING **：由於默認包的@ComponentScan，您的ApplicationContext不太可能啓動。」當啓動應用程序得到了以下信息：

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)

在pom.xml中，包括以下的父母，依賴條件

<parent> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-parent</artifactId> 
     <version>1.3.5.RELEASE</version> 
    </parent> 

    <dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-data-mongodb</artifactId> 
    </dependency> 

會是怎樣的問題？

Answer 1

問題是主要類（將實現「CommandLineRunner」）應該在特定的包而不是默認包。其他DAO也應該在相同或者子級別。現在我可以更新和查看數據到/從monogoDB
