Spring Boot 启动报错

错误代码：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: URL [jar:file:/C:/Users/Administrator/.m2/repository/org/springframework/boot/spring-boot-autoconfigure/1.3.1.RELEASE/spring-boot-autoconfigure-1.3.1.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/dao/DataAccessException 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)

错误原因 :

　　application.java 文件不能直接放在main/java文件夹下，必须要建一个包把他放进去
