配置文件
我们注释掉原来的zk依赖换上最后三个依赖就可以了；
配置只需要变更一个
生产者

server.port=38080
dubbo.application.name = demo-server
# 注册中心地址,去哪找服务
#dubbo.registry.address = zookeeper://127.0.0.1:2181
dubbo.registry.address = nacos://159.23.11.316:8848
dubbo.registry.client = zkclient
dubbo.registry.timeout = 60000
dubbo.consumer.timeout = 60000

#qos
dubbo.application.qos.enable=true
dubbo.application.qos.port=33333
dubbo.application.qos.accept.foreign.ip=false

消费者

server.port=38081
#要把那些服务注册到注册中心
dubbo.scan.basePackages = com.doria.provider
dubbo.application.name = demo-provider
# rpc通讯名称
dubbo.protocol.name = dubbo
# rpc通讯端口
dubbo.protocol.port = -1
# 注册中心地址,把服务注册到哪
#dubbo.registry.address = zookeeper://localhost:2181
dubbo.registry.address = nacos://159.23.11.316:8848
dubbo.registry.client = zkclient
dubbo.registry.timeout = 10000

zookeeper://127.0.0.1:2181 变更为nacos://159.23.11.316:8848
