springboot項目部署tomcat的問題

由於springboot內置了tomcat，能夠jar 啓動 可是我想要war部署tomcat啓動，方便修改tomcat配置文件 修改springboot入口繼承SpringBootServletInitializer 實現configure方法 入下：

public class CloudAutoStudyApplication extends SpringBootServletInitializer {

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