原因分析
message can not send, because channel is closed 远程方法调用失败,提示通道被关闭，无法发送信息
打开dubbo的管理页面:出现此异常是,对应下图服务应该是不存在的.(下图是服务已经提供出去后正确的显示)
1. 检查服务提供的配置文件是否正确,配置文件是否加载
dubbo_provider.xml 提供服务的文件
bean.xml 加载 dubbo_provider.xml 配置文件
2.检查客户端、服务端的超时配置；如果超时时间没有设置，设置为一个较长时间，就可以了
3.检查你调用服务所在机器ip地址与你调用端配置的ip地址端口是否一致,如下红色url地址
dubbo_customer.xml 调用服务的配置
4.检查发布服务的项目是否启动正常,发布服务的项目没有正常启动也会出现此问题
