    Instead of posting github link you entire of your project Provide snippets of your relevant pieces of codes here. Nobody would like to brows through the github repo to find your problem Commented Oct 18, 2018 at 0:32

    Just for readability, consider putting the Exception in a ´´´ block. Commented Dec 18, 2019 at 8:01

I found your project to be running fine at my end, few things you might try to work at your end.

  1. Try changing to spring.datasource.driverClassName=com.mysql.jdbc.Driver

  2. Remove @ComponentScan() from main class and just leave @SpringBootApplication there.

    @SpringBootApplication
    public class TrialApplication{    
        public static void main(String[] args) {
            SpringApplication.run(TrialApplication.class, args);
        }       
    }
  1. Clean your project by project-->rebuild/clean or run command mvn clean install or removing .m2/repository or re-import project or restarting IDE/system might help.
