Dubbo zookeeper 初探

1.zookeeper

http://zookeeper.apache.org/ 官网下载，然后安装

启动时，需要将 zoo_sample.cfg 改成 zoo.cfg

 

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=D:\\Zookeeper-3.4.5\\data
# the port at which the clients will connect
clientPort=2181
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

2. dubbo-demo-api  定义接口

 

 

public interface IProcessData {
    public String deal(String data);
}

3.dubbo-demo-provider 服务提供者

 

 

public class ProcessDataImpl implements IProcessData {

    /*
     * @see com.xxx.bubbo.provider.IProcessData#deal(java.lang.String)
     */
    @Override
    public String deal(String data) {
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return "Finished:" + data;
    }
}

 

provider.xml配置

启动服务

public class DubboProviderMain {

    /**
     * @Title main
     * @Description TODO
     * @Author weizhi2018
     * @param args
     * @throws
     */

    public static void main(String[] args) throws Exception {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
                new String[]{"provider.xml"});
        context.start();

        System.out.println("Press any key to exit.");
        System.in.read();
    }
}

3.dubbo-demo-consumer

 

public class ConsumerThd implements Runnable {

    /*
     * @see java.lang.Runnable#run()
     */
    @Override
    public void run() {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
                new String[]{"consumer.xml"});
        context.start();

        IProcessData demoService = (IProcessData) context.getBean("demoService"); // get
                                                                                // service

        // proxy
        String hello = demoService.deal("nihao"); // do invoke!

        System.out.println(Thread.currentThread().getName() + " "+hello);
    }

4.dubbo-admin

 

下载dubbo-admin项目，部署到tomcat6下面，启动tomcat ，在浏览器打开：http://localhost:8080/dubbo-admin, 输入用户名/密码：root/root
