问题分析

本以为是配置问题，分析后不是：

spring:
  application:
    name: cyb-dubbo-provider

customer:
  address: 192.168.10.5:2181
  protocol: zookeeper

dubbo:
  application:
    name: ${spring.application.name}
  protocol:
    name: dubbo
    port: 28080
  registry:
    id: zk-lch
    timeout: 2500000
    address: ${customer.address}
    protocol: ${customer.protocol}
    parameters:
      blockUntilConnectedWait: 250
  configCenter:
    timeout: 2500000
    address: ${customer.address}
    protocol: ${customer.protocol}
    parameters[init.timeout]: 60000
  metadataReport:
    address: ${customer.address}
    protocol: ${customer.protocol}
  scan:
    base-packages: com.cyb.dubbo.provider.service.impl

又以为是服务问题，查看后不是：

还以为是依赖包问题，真是：

错误依赖：

  org.apache.dubbo
  dubbo
  2.7.18


  org.apache.curator
  curator-recipes
  2.8.0

正确依赖：

  org.apache.dubbo
  dubbo
  2.7.18


  org.apache.curator
  curator-recipes
  5.3.0

解决方案

升级依赖curator-recipes的版本至高版本，要与dubbo版本匹配！！！！
