  • 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

     1、DemoService

            String msg = "欢迎您:" + name + " IP地址：" + getIP();

            } 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
