Question

我一直在努力让Camel Netty4 udp多播在Windows上工作，而NettyUDPMulticastAsyncTest似乎失败了java.nio.channels.ClosedChannelException。同样的测试似乎在OSX上工作。这两台机器都运行Java 1.7 我已经更新了测试中的接口名称，并且能够在同一个接口上运行NIO UDP多播示例。我使用的是Camel 2.14.1，但它似乎也不适用于2.15.x.

堆栈跟踪在下面。

在加入组之前发现绑定到多播地址的问题，由于某种原因在Windows上不起作用。不得不在 SingleUDPNettyServerBootstrapFactory

中更新bootstrap.bind看起来像这样

ChannelFuture channelFuture = bootstrap.bind（new InetSocketAddress（configuration.getPort（）））;

Camel Netty4 udp组播无法在Windows上运行
