It seems you havent mentioned datasource configuration. Spring Boot is not able to auto-configure a DataSource. To do so, add some properties to application.properties with the spring.datasource prefix.

Refer DataSourceProperties for all properties that you can set.

You'll need to provide the appropriate url and driver class name:

 spring.datasource.url = …
 spring.datasource.driver-class-name = …
