Gradle Spring Boot project not working in Tomcat as a WAR

I have a simple sample application written in Spring Boot using Gradle dependency. It says helloworld on calling localhost:8080/greetings. I packaged it as WAR and deployed it to a Tomcat as a myWebApp.war.

When i call localhost:8080/myWebApp/greetings i get 404. What am i supposed to infer from the below catalina.log

To run a Spring Boot application in a standalone servlet container you need to tell the container how to launch the application. You do so by extending SpringBootServletInitializer and overriding the configure method to provide the configuration classes for your application. This is described in the getting started guide on converting a jar to a war.

You typically end up with a class like this:

@Configuration
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

    // Used when launching as an executable jar or war
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

    // Used when deploying to a standalone servlet container
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}
