APPLICATION FAILED TO START

Description:
Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-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).
Process finished with exit code 0
原因依赖中添加了数据层依赖，springboot启动时自动注入DataSource，还没配置所以报错。
注释掉数据层即可。
