public class SpringbootApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);
    }
    //重写configure方法
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(SpringbootApplication.class);
    }
}
