Dubbo入门,搭建Dubbo 测试服提供与消费

• 1.首先安装zookeeper,网上很多资料,略过

• 2.下载并且安装tomcat linux版本

下载地址:http://tomcat.apache.org/download-70.cgi

上传到服务器,并且解压

[root@lijie java]# tar -xzvf apache-tomcat-7.0.29.tar.gz

• 3.下载dubbo-admin的war包

dubbo-admin-2.5.4-SNAPSHOT.war ,链接地址:http://download.csdn.net/detail/evankaka/9054273

• 4.部署dubbo-admin

    [root@lijie java]# cp ./dubbo-admin-2.5.4-SNAPSHOT.war ./apache-tomcat-7.0.29/webapps/    [root@lijie java]# ./apache-tomcat-7.0.29/bin/startup.sh 

注意: 修改WEB-INFO下面的dubbo.properties的zookeeper地址等,并重启tomcat

• 5.在浏览器中访问

在浏览器上面访问地址:http://192.168.80.123:8080/dubbo-admin-2.5.4-SNAPSHOT

之后会让你输入账号密码:默认账号root 默认密码root

登入之后:

• 6.创建两个maven工程

一个服务消费,一个服务提供,工程图如下:

• 6.1 dubbo-pp 服务提供

DubboServer

package com.lijie.producer;public interface DubboServer{    String hello();}

DubboServerImpl

package com.lijie.producer.impl;import org.springframework.stereotype.Service;import com.lijie.producer.DubboServer;@Service("dubboServerImpl")public class DubboServerImpl implements DubboServer{    @Override    public String hello() {        System.out.println("被訪問!");        return "world!";    }}

MainApp

package com.lijie.producer.main;import java.io.IOException;import org.springframework.context.support.ClassPathXmlApplicationContext;public class MainApp {    public static void main(String[] args) {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(                "classpath*:applicationContext.xml");        context.start();        System.out.println("begin");        try {            System.in.read();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
