springboot项目在启动时，报如下错误：
Error starting ApplicationContext. To display the auto-configuration report re-run your application with ‘debug‘ enabled. 2019-09-09 20:47:28.395 ERROR 16240 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter : *************************** APPLICATION FAILED TO START *************************** Description: Cannot determine embedded database driver class for database type NONE Action: If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).
原因：
在项目的pom.xml文件中有引入数据库的配置，如下，但在实际上在项目中没有配置数据库的链接，所以报错。
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency>
解决方案：
在项目的application.properties配置数据库的链接。
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/cds
spring.datasource.username=cds
spring.datasource.password=cds
Springboot 之 启动报错-Cannot determine embedded database driver class for database type NONE
