SCA版本; 2.1.1.RELEASE dubbo版本: 2.7.4.1 nacos版本: 1.1.4 spring boot版本: 2.1.7.RELEASE dubbo 提供者项目,部分配制在nacos中, 没有引入 spring-boot-starter-web 的包, 并以非web方式启动

new SpringApplicationBuilder(xxx.class)
                // 非 Web 应用
                .web(WebApplicationType.NONE)
                .run(args);

修改了nacos 里的配制后,触发了 shutdown, 下面是部分日志

临时解决方案:

但是这样搞启动后第一次修改的时候还是会触发 shutdown(shutdown日志还是输出了), 不过并没有真正 shutdown, 提供者也能正常调用. 第二次~第N次修改就不会触发shutdown 了.
