Class File:

package fr.gouv.esignature.dss;    
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DssApplication {

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

}
