Spring Boot Webflux 中的 Unix 域套接字配置

Question

Spring 引导版本：2.4.0
Reactor netty 现在在初始化服务器时支持Unix 域 Sockets 。

我正在尝试自定义 Spring 引导HttpServer以使用 unix 域套接字而不是 http 端口使用

@Configuration
public class NettyConfig {

    @Bean
    public NettyReactiveWebServerFactory factory() {
        NettyReactiveWebServerFactory factory = new NettyReactiveWebServerFactory();
        factory.setServerCustomizers(Collections.singletonList(new NettyServerCustomizer() {
            @Override
            public HttpServer apply(HttpServer httpServer) {
                return httpServer.bindAddress(() -> new DomainSocketAddress("/tmp/test.sock"));
            }
        }));
        return factory;
    }
}

但是应用程序无法从给定的堆栈跟踪开始：
