SpringBoot的错误 Failed to read candidate component class

springboot 启动错误 显示错误是

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/2.0.2.RELEASE/spring-boot-autoconfigure-2.0.2.RELEASE.jar!/org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$EmbeddedDatabaseConfiguration.class]; nested exception is java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$EmbeddedDatabaseConfiguration 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)at t.annotation.ClassPathScanningCandidateComponentProvider.scanCandidateComponents(ClassPathScanningCandidateComponentProvider.java:454) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE]at t.annotation.ClassPathBeanDefinitionScanner.doScan(ClassPathBeanDefinitionScanner.java:275) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE]at t.annotation.ComponentScanAnnotationParser.parse(ComponentScanAnnotationParser.java:132) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE]at t.annotation.ConfigurationClassParser.doProcessConfigurationClass(ConfigurationClassParser.java:288) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE]at t.annotation.ConfigurationClassParser.processConfigurationClass(ConfigurationClassParser.java:245) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE]at t.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:202) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE]at t.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:170) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE]

我本来的路径是这样的

这是是因为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
正确应该是放到包里面

启动成功
