嗨，当我运行我的 Spring Boot 应用程序时，我收到了这条消息。我的主类有@SpringBootApplication，看起来像：

@SpringBootApplication
public class SouscriptionServiceOptionnelApplication extends SpringBootServletInitializer implements WebApplicationInitializer {
  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    return configureApplication(builder);
  }
  public static void main(String[] args) {
    configureApplication(new SpringApplicationBuilder()).run(args);
  }
  private static SpringApplicationBuilder configureApplication(SpringApplicationBuilder builder) {
    return builder.sources(SouscriptionServiceOptionnelApplication.class);
  }

POM.XML 看起来像：
