我的运行环境是跨物理计算机，两台物理电脑。
在局域网中运行客户端时出现上面的异常，
奇怪的是第一个异常：
org.apache.dubbo.remoting.RemotingException: client(url:
dubbo://192.168.59.18:20880/com.class09.www.service.IService?anyhost=true&application=dubbo1-client&check=false&codec=dubbo&default=true&deprecated=false&dubbo=2.0.2&dynamic=true&generic=false&heartbeat=60000&interface=com.class09.www.service.IService&methods=sayHello&pid=7328&qos.port=33333®ister.ip=192.168.59.18&release=2.7.5&remote.application=dubbo1-server&side=consumer&sticky=false×tamp=1578984874892)
failed to connect to server /192.168.59.18:20880, error message is:Connection
refused: no further information: /192.168.59.18:20880
192.168.59.18这个IP是我的IP，服务端根本不在本地，为什么要连接本地呢？连接本地当然报错了，搞了一下午，请教一下啊！
