Spring Boot application gives 404 when deployed to Tomcat but works with embedded server

Question

Guided by Serving Web Content with Spring MVC, I\'m creating a Spring Boot web application that I can run using both the embedded Tomcat instance as well as on a standalone Tomc

Answer 1

I had forgotten to tweak my Application.java file to extend SpringBootServletInitializer and override the configure method.

Corrected file:

@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);
  }
}
