uc启动不了，不知道为啥找不到数据库配置

[shenzhuan]

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).

同样启动不了，报错could not cteate connection to database server。是需要另外创建数据库么，还是项目自己内部会创建？
