springboot项目启动异常

Description:

Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

Action:

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).

在你确认别的地方没有问题的情况下，依旧报这个错
可以尝试Rebuild Module ‘xxx’
虽然不清楚原理 但我就是怎么好的 记录一下
也希望可以帮到大家！
