我们遇到问题的场景是 测试同学通过异步调用的方式测试Dubbo同步调用的服务，单测跑完了，但测试的异步回调还在尝试获取结果，就触发了这个问题。

Caused by: com.alibaba.dubbo.remoting.RemotingException: 
message can not send, because channel is closed.

问题原因是调用通道已关闭引起服务方法调用失败。

有同样的问题，我是直接跑的demo，在网上找了半天，说是因为网络不通。 导致网络不通的问题有很多：

• 检查有没有虚拟网卡（例如wifi共享精灵这种，虚拟机等）
• 防火墙

我禁用了VMWare的虚拟网卡，然后还是不行。 之后想到我装了Avast杀毒软件，带了有个防火墙，在防火墙里面给JRE设置例外就行了。
