Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.

🆘 How I solved the errors that I encountered

Error message

Solution

This was easily solved by adding the following (exclude = DataSourceAutoConfiguration.class) next to @SpringBootApplication.

Full code

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication (exclude = DataSourceAutoConfiguration.class)
public class YourApplication {

    public static void main(String[] args) {
        SpringApplication.run(YourApplication.class, args);
    }
}
