【dubbo】消费者Consumer搭建

一.consumer搭建（可以web/jar）

1.新建Maven项目，groupId：com.dubbo.consumer.demo artifactId:demo projectName:dubboo-consumer-demo

2.新建class ：com.dubbo.consumer.demo.DemoAction

package com.dubbo.consumer.demo;

import java.text.SimpleDateFormat;
import java.util.Date;
import com.dubbo.api.demo.*;
/**
 * Created by Administrator on 17-1-7.
 */
public class DemoAction {
    private static DemoService demoService;
    public void setDemoService(DemoService demoService) {
        this.demoService = demoService;
    }

    public void start() throws Exception {
        for (int i = 0; i < Integer.MAX_VALUE; i ++) {
            try {
                String hello = demoService.sayHello("world" + i);
                System.out.println("[" + new SimpleDateFormat("HH:mm:ss").format(new Date()) + "] " + hello);
            } catch (Exception e) {
                e.printStackTrace();
            }
            Thread.sleep(2000);
        }
    }
}

3.添加配置文件spring-dubbo-consumer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    <dubbo:application name="dubbo-consumer-demo" ></dubbo:application>
    <dubbo:registry address="zookeeper://127.0.0.1:2181" protocol="zookeeper"></dubbo:registry>
    <dubbo:reference id="demoService" interface="com.dubbo.api.demo.DemoService" ></dubbo:reference>

</beans>

4.修改maven配置文件pom.xml,添加spring、dubbo、dubbo-api

<dependencies>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.4.10</version>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>3.2.16.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.2.16.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>3.2.16.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>com.dubbo.api.demo</groupId>
            <artifactId>dubbo-interface</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

5.添加消费者Class DemoConsumer

 */

import com.dubbo.api.demo.*;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class DemoConsumer {

    public static void main(String[] args) {

        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("META-INFO/spring-dubbo-consumer.xml");

        ctx.start();

        DemoService demoService = (DemoService) ctx.getBean("demoService");

        String hello = demoService.sayHello("world" + 1);
        System.out.println("[" + hello);

        ctx.close();
    }
    }

二、总结

1.web或jar包形式发布消费者都可以

2.工程中涉及主要配置

A.consumer.xml 中引入API(interface)

B.pom.xml中引入API(Interface)jar包

C.接口实现在provider中完成，本地引入接口定义jar即可

D.java中import api package
