spring cloud（学习笔记）微服务启动错误（1）

今天下午在启动spring cloud微服务的时候，报了这个错误：

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.
2018-07-03 20:17:10.295 ERROR 19024 --- [ 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).

Disconnected from the target VM, address: '127.0.0.1:55393', transport: 'socket'

Process finished with exit code 1

刚开始我以为是端口被占用。果断cmd并输入netstat -aon，找半天没发现占用的端口，然后又网上看了一下，

SpringBoot启动报错：Cannot determine embedded database driver class for database type NONE

springboot启动时会自动注入数据源和配置jpa
