推荐答案

与sql数据库的连接，必须在application.properties中配置数据源

the connection with a sql database, you must configure datasource in application.properties

spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://.. spring.datasource.username=//.. spring.datasource.password=//..
