为什么继承SpringBootServletInitializer

@SpringBootApplication
@ServletComponentScan
@MapperScan(basePackages = {"com.xxx.dao"})
@EnableTransactionManagement
@EnableAsync
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);
    }
}
