這個問題怎樣解決？？？？
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).

yml 里的datasource 看看是不是空格沒對齊。和profile對齊，不是和dev對齊

Application?類?@SpringBootApplication?注解后加(exclude=?{DataSourceAutoConfiguration.class})2018-06-20
檢查一下你的數據庫是否啟動，配置的url信息是否正確。
