【dubbo】dubbo项目基本结构及provider构建

2023-07-24 08:47:34

dubbo项目基本结构如下，分别部署于不同服务器：

1.provider(接口API 实现)

2.consumer(web)

3.zookeeper

4.DB

provider构建

1.api构建

intellij中新建"maven"项目，groupId：com.dubbo.api.demo，artifactId：demo，projectName:dubbo-api-demo();

java下添加interface:cmo.dubbo.api.demo.DemoService;

public interface DemoService {

    String sayHello(String name);

}

maven-install

2.provider 实现构建

pom.xml中添加DUBBO-API,DUBBO,SPRING

<dependencies>

　　<dependency>

            <groupId>com.dubbo.api.demo</groupId>

            <artifactId>demo</artifactId>

            <version>1.0-SNAPSHOT</version>

　　</dependency>

　　

<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>

</dependencies>

intellij中新建"maven"项目，groupId：com.dubbo.provider.demo，artifactId：demo，projectName:dubbo-provider-demo();

java下添加class:cmo.dubbo.provider.demo.DemoServiceImpl：

package com.dubbo.provider.demo;

import java.text.SimpleDateFormat;

import java.util.Date;

import com.alibaba.dubbo.rpc.RpcContext;

import com.dubbo.api.demo.*;

/**

 * Created by Administrator on 17-1-1.

 */

public class DemoServiceImpl implements DemoService {

    public String sayHello(String name) {

        System.out.println("[" + new SimpleDateFormat("HH:mm:ss").format(new Date()) + "] Hello " + name + ", request from consumer: " + RpcContext.getContext().getRemoteAddress());

        return "Hello " + name + ", response form provider: " + RpcContext.getContext().getLocalAddress();

    }

}

resources下添加dubbo配置META-INFO.spring-dubbo-provider.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">

    <dubbo:application name="dubbo-provider-demo" ></dubbo:application>

    <dubbo:registry id="zk1" address="zookeeper://127.0.0.1:2181" protocol="zookeeper"></dubbo:registry>

    <dubbo:protocol id="mydubbo" name="dubbo" port="20886"></dubbo:protocol>

    <dubbo:provider register="zk1" protocol="mydubbo"></dubbo:provider>

    <dubbo:service interface="com.dubbo.api.demo.DemoService" ref="demoService"></dubbo:service>

    <bean id="demoService" class="com.dubbo.provider.demo.DemoServiceImpl" />

</beans>

启动provider,在Edit Configuration 中添加application 的启动方法，main class选择com.alibaba.dubbo.container.Main。控制台显示[2017-01-07 15:07:25] Dubbo service server started! 则表示成功启动
