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

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
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:
