import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import  org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer{

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder     application) {
        return application.sources(Application.class);
    }

}

Is this the full error message? Did you check the "catalina.log" file?

To me it looks like you could forget to provide MYSQL driver on the remote Tomcat.

Try copying the driver to the Tomcat's "lib" directory and configure it properly like in this example: Tomcat MYSQL DBCP
