spring-boot - Springboot 2 RSocket 应用程序启动然后立即停止，没有错误消息

Question

我只是选择了一个带有 RSocket 启动器的 springboot 应用程序示例： 构建，然后运行可运行的 jar 给我以下日志：

Process finished with exit code 0

问题是 Springboot 主线程立即停止而无需等待 RSocket 请求。我想问题是 RSocket 服务器没有启动所以我尝试添加一个这样的 RSocket 控制器：

@Controller
public class DemoController {

    @MessageMapping("retreiveSomeData")
    public Mono<Data> retreiveAccount(String criteria) {
        return Mono.just(new Data());
    }

}

结果一样^^

任何使用带有 SpringBoot 的 RSocket 的人都找到了一种强制 Springboot 线程等待的“漂亮”方法？

解决方案是添加一个 RSocket 配置。

只需添加以下内容application.yaml：

# application.yaml
spring:
  rsocket:
    server:
      port: 7000

然后 Netty 服务器将在端口 7000 上启动：
