Springboot 2.5.1集成 mybatis-plus-boot-starter 3.3.2 报错

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
