SpringBoot启动报错Failed to determine a suitable driver classSpringBoot启动报错Failed to determine a suitable driver class
我的错误原因与网上其他的原因不同，故记录
项目结构：
我的项目是有继承关系的多模块结构
其中springboot的启动项在api模块中，由于项目原因，我将api模块中的springboot配置文件后缀由properties修改为yml后，出现了如下报错
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).
于是我按照网上的解决方案尝试修复，均不见效，最后是将后缀名改回properties才恢复正常（配置文件是空的）
不清楚错误原因
