I followed the instruction from here Using Spring Data JPA on Google Appengine 解决方案 You haven't provided Spring Boot with enough information to auto-configure a DataSource. To do so, you'll need to add some properties to application.properties with the spring.datasource prefix. Take a look at DataSourceProperties to see all of the 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 = … 这篇关于Spring Boot - 无法确定数据库类型为NONE的嵌入式数据库驱动程序类的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
