原因分析

message can not send, because channel is closed   遠程方法調用失敗,提示通道被關閉，無法發送信息

打開dubbo的管理頁面:出現此異常是,對應下圖服務應該是不存在的.(下圖是服務已經提供出去后正確的顯示)

 

1. 檢查服務提供的配置文件是否正確,配置文件是否加載

dubbo_provider.xml  提供服務的文件

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

bean.xml  加載 dubbo_provider.xml  配置文件

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

2.檢查客戶端、服務端的超時配置；如果超時時間沒有設置，設置為一個較長時間，就可以了

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

3.檢查你調用服務所在機器ip地址與你調用端配置的ip地址端口是否一致,如下紅色url地址

dubbo_customer.xml  調用服務的配置

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

4.檢查發布服務的項目是否啟動正常,發布服務的項目沒有正常啟動也會出現此問題
