Cannot determine embedded database driver class for database type NONE

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).

问题：

1.我使用的是springboot ，配置文件是后缀为yml格式的，然而程序不知道我什么不识别后缀文件为yml的配置文件，改为application.properties就能识别了，不理解。

解决方法：

说是找不到数据库

1.pom中加

<dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <scope>runtime</scope> </dependency>

2.把application.yml格式的配置文件改为application.properties就OK
