Dubbo_创建Dubbo服务并在ZooKeeper注册，然后通过Jar包执行



一、安装ZooKeeper（略）

二、创建Dubbo服务

public class DemoService implements IDemoService {
  
    public String sayHello(String name) {
        String msg = "欢迎您:" + name + " IP地址：" + getIP();
        System.out.println(msg);
        return msg;
    }
  
  
    private String getIP() {
        InetAddress addr = null;
        try {
            addr = InetAddress.getLocalHost();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
        String ip = addr.getHostAddress();//获得本机IP
        String address = addr.getHostName();//获得本机名称
        return ip;
    }
}

三、打包Dubbo服务

1、使用maven进行打包，先运行clean  再运行install


四、启动Dubbo服务

1、把jar文件和lib文件夹拷贝到C盘DemoServiceJars目录下


2、命令行定位到C盘DemoServiceJars目录下，执行java -jar dub-service-demo.jar


3、ZooKeeper检测到该服务



4、Linux启动Dubbo的方式也是执行：java -jar dub-service-demo.jar&


五、注意事项

1、配置文件dubbo-provider.xml必须放在resource-->spring文件夹下，否则dubbo就算显示启动成功， 实际上也没有启动

2、源码请从群中下载
