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

<dubbo:service interface="com.ys.xxxx.xxxx.xxxx" ref="xxxxImpl"   version="1.0" />

bean.xml  加载 dubbo_provider.xml  配置文件

<import resource="classpath*:/dubbo_provider.xml" />

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

<dubbo:consumer check="false" timeout="300000" />
    <dubbo:provider timeout="300000" />

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

<dubbo:reference id="xxxx" interface="com.ys.xxxx.xxx.xxxxApi" url="dubbo://10.20.30.164:21331" version="1.0"  />

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
