Tomcat 8 does not recognize Api REST

I have a Rest API created with Java 1.7, using spring boot. When I start the server in eclipse (which uses an embedded tomcat) the application works correctly and when I show localhost: 8080 / hello the message appears in JSON "Hello World".

Now, I have a machine with Centos 7 and tomcat 8 installed (it's a clean installation, I only have it for testing), in which I deploy the generated war. From App Manager I can see that the war is running.

But when I try to access the war, or just call the Rest API, it returns 404.

I've tried with the directions: localhost: 8080 / hello localhost: 8080 / demo-demo / hello localhost: 8080 / demo-demo.war / hi

Do I have to configure something else? What can be failing?

Thank you very much in advance.

EDIT

I have reviewed the logs. You can see this:

EDIT:

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

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