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 1

spring.datasource.url' is not specified and no embedded datasource could be auto-configured.
翻译:“spring.datasource。未指定url'，也无法自动配置嵌入式数据源。
解决方法:检查application.yml中的数据库连接信息是否正确
