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).


Process finished with exit code 1

原因是：springboot启动时会自动注入数据源和配置jpa 

解决：在@SpringBootApplication中排除其注入

需要在启动类的@EnableAutoConfiguration或@SpringBootApplication中添加exclude = {DataSourceAutoConfiguration.class}
