最近发现dubbo消费端一直报下面这样的error日志

该个error对项目的功能没有任何影响,但反复的报错也是让人心烦,那么就解决吧。

原因

没有启动监控中心,却配了监控地址。

解决方案

  1. 把监控中心启动
  2. 把xml配置中的<dubbo:monitor protocol=“registry”>
  3. properties配置中的dubbo.monitor.protocol=registry去掉

dubbo:monitor

监控中心配置。对应的配置类: org.apache.dubbo.config.MonitorConfig

属性 对应URL参数 类型 是否必填 缺省值 作用 描述 兼容性
protocol protocol string 可选 dubbo 服务治理 监控中心协议,如果为protocol=“registry”,表示从注册中心发现监控中心地址,否则直连监控中心。 2.0.9以上版本
address string 可选 N/A 服务治理 直连监控中心服务器地址,address=“10.20.130.230:12080” 1.0.16以上版本
