spring dubbo 配置，项目中连接多个注册中心

如果项目需要连接多个ZooKeeper，则定义多个dubbo:registry，对应的dubbo:reference与dubbo:service指定的注册中心registry="registry1"。

</beans>

system.dubbo.application = ${system.dubbo.application}
system.dubbo.registry1= ${system.dubbo.registry1}
system.dubbo.registry2= ${system.dubbo.registry2}

dubbo.reference.check = false

 配置文件中的${}，请看  maven多环境配置打包

system.dubbo.application = ***_dev_service
system.dubbo.registry1= zookeeper://192.168.0.81:2181
system.dubbo.registry2= zookeeper://192.168.0.82:2181
