ERROR 1384 --- [  restartedMain] o.s.b.d.LoggingFailureAnalysisReporter  






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 0




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


@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})




加了之后，又报错
