我们在本地测试时经常会遇到这种问题
15:27:51.293 [http-nio-8083-exec-3] [ERROR] c.s.test.web.controller.BaseController - 【Exception】test_web系统出现异常
com.alibaba.dubbo.rpc.RpcException: Forbid consumer 192.168.18.145 access service com.test.api.UserInfoApi from registry 127.0.0.1:20080 use dubbo version 2.8.4x, Please check registry access list (whitelist/blacklist).

意思是服务没有提供者
需要我们看服务是否注册成功，
首先进入zookeeper的bin目录下
查看本地zookeeper的注册
输入命令行
./zkCli -server 127.0.0.1:2181
windows 电脑使用 zkCli.cmd 命令
Linux或者mac 使用 zkCli.sh 命令
进入目录，即可查看消费者或者提供者
查看提供者
ls /dubbo/com.test.api.UserInfoApi/providers
未注册成功
[]
注册成功

查看消费者
ls /dubbo/com.test.api.UserInfoApi/consumers
返回结果同上
