Solution 1:[1]

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=//..

Solution 2:[2]

if you dont need to config the datasource, you can use the exclude . like this:

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
