dubbo未注册服务

触发访问调用出现如下错误

com.alibaba.dubbo.rpc.RpcException: Forbid consumer 172.16.70.120 access service service.UserService from registry 118.144.137.xxx:2181 use dubbo version 2.8.4, Please check registry access list (whitelist/blacklist).

    at com.alibaba.dubbo.rpc.proxy.InvokerInvocationHandler.invoke(InvokerInvocationHandler.java:52)
    at com.alibaba.dubbo.common.bytecode.proxy0.save(proxy0.java)

这个代表服务未注册上

解决问题的思路是：
