发布Dubbo服务

首先创建一个maven项目

1.New > Other > Maven Project > Next

2.勾选Create a simple project (skip archetype selection) > Next

3.填好Group Id 和 Artifact Id 后 Finish

pom.xml添加依赖

pom.xml：

<dependencies>

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>dubbo</artifactId>
        <version>2.6.0</version>
    </dependency>

    <dependency>
        <groupId>com.101tec</groupId>
        <artifactId>zkclient</artifactId>
        <version>0.10</version>
    </dependency>

    <dependency>
        <groupId>org.apache.curator</groupId>
        <artifactId>curator-framework</artifactId>
        <version>4.0.1</version>
    </dependency>

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
        <version>1.2.46</version>
    </dependency>

    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.25</version>
    </dependency>

    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-lang3</artifactId>
        <version>3.4</version>
    </dependency>

    <dependency>
        <groupId>io.netty</groupId>
        <artifactId>netty-all</artifactId>
        <version>4.0.35.Final</version>
    </dependency>

</dependencies>

定义一个服务提供者接口

DemoProviderService：

package com.icat.service;

/**
 * 服务提供者接口
 * @author icat
*
 */

public interface DemoProviderService {

    public String sayHello(String name);

}

定义一个服务提供者接口实现类

DemoProviderServiceImpl：

package com.icat.service.impl;

import com.icat.service.DemoProviderService;

/**
 * 服务提供者接口实现类
 * @author icat
 *
 */
public class DemoProviderServiceImpl implements DemoProviderService {

  public String sayHello(String name) {
    return "服务提供者 -------------- " + name;
  }

}

创建dubbo-demo-provider.xml

在src/main/resources 下创建配置文件 dubbo > dubbo-demo-provider.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

  <!-- 服务提供方应用名称，用于计算依赖关系 -->
  <dubbo:application name="demo-provider"/>

  <!-- 这里我们使用本地zookeeper注册中心暴露服务地址 127.0.0.1:2181-->
  <dubbo:registry address="zookeeper://127.0.0.1:2181"/>

  <!-- 使用dubbo协议，在20880端暴露服务 -->
  <dubbo:protocol name="dubbo" port="20881"/>

  <!-- service实现类作为本地的一个bean -->
  <bean id="demoProviderService" class="com.icat.service.impl.DemoProviderServiceImpl"/>

  <!-- 声明需要暴露的dubbo服务提供方接口 -->
  <dubbo:service interface="com.icat.service.DemoProviderService" ref="demoProviderService"/>
</beans>

创建测试类

ProviderTest：

package test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ProviderTest {

  public static void main(String[] args) throws Exception {
    ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
        new String[] { "dubbo/dubbo-demo-provider.xml" });
    context.start();
    System.out.println("服务提供者向zookeeper注册中心注册服务成功>>>>>>>>>>>port:20881");
    System.in.read(); // 按任意键退出
    context.close();
  }

}
