You can fix this problem in two ways

Method-1: Fixing with application.properties file

you can add the fallowing line in application.properties file

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

Method-2: Fixing with Code

You can add EnableAutoConfiguration annotation with DataSourceAutoConfiguration exclude like below

@SpringBootApplication
@EnableAutoConfiguration (exclude = { DataSourceAutoConfiguration.class })
public class SpringbootApplication {
	SpringApplication.run(SpringbootApplication.class, args);
}

or you can also add excludes to the SpringBootApplication annotation itself

@SpringBootApplication (exclude = { DataSourceAutoConfiguration.class })
public class SpringbootApplication {
	SpringApplication.run(SpringbootApplication.class, args);
}
