带有mongodb弹簧数据的Spring启动：加载应用程序时出错

我正在使用mongoDB在spring boot中测试spring数据 得到消息＆＃34; **警告**：由于默认包的@ComponentScan，您的ApplicationContext不太可能启动。＆＃34;在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)

在pom.xml中，包括以下父项，dependecies 

   <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>

会出现什么问题？

1 个答案:

答案 0 :(得分：3)

问题是主类（将实现＆＃34; CommandLineRunner＆＃34;的那个）应该在特定包而不是默认包中。其他DAO也应该在相同或次级。现在我能够更新和查看monogoDB的数据
