创建一个父工程springdubbo，3个子工程分别为服务端provider，客户端consumer
，接口api
选择都选择maven quickstart即可

在main目录下面创建resources文件夹，并且让idea识别，选择中右击：

Spring基础环境搭建_Dubbo

给父工程添加依赖，这样provider和consumer最为子项目都可以依赖，由于pom文件中的依赖子项目都需要，因此，吧依赖都添加到父工程的pom文件中。

服务端provider配置如下：
创建配置文件
applicationContext-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:context="http://www.springframework.org/schema/context"
     xmlns:aop="http://www.springframework.org/schema/aop"
     xmlns:tx="http://www.springframework.org/schema/tx"
     xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
     xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
    http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
    ">
  <!-- 提供方应用信息，用于计算依赖关系 -->
  <dubbo:application name="provider"/>

  <!--使用zookeeper进行注册中心化-->
  <dubbo:registry address="zookeeper://localhost:2181"/>

  <!-- 用dubbo协议在20880端口暴露服务 -->
  <dubbo:protocol name="dubbo" port="20880"/>

  <!-- 和本地bean一样实现服务 -->
  <bean id="serviceAPI" class="com.gblfy.dubbo.api.impl.ServiceAPIImpl"/>

  <!-- 声明需要暴露的服务接口 -->
  <dubbo:service
      interface="com.gblfy.dubbo.api.ServiceAPI"
      ref="serviceAPI"/>
</beans>

创建一个接口实现类

public class ServiceAPIImpl implements ServiceAPI {
    @Override
    public String sendMessage(String message) {
        return "quickstart-provider-message="+message;
    }
}

创建一个客户端

public class ProvierClient {
    /**
     * 1.读取配置文件
     * 2.创建ioc容器
     * 3.堵塞（状态停留，输入停止，不输入就状态一直保留）
     *
     * @param args
     */
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-provider.xml");
        context.start();
        try {
            System.in.read(); // 按任意键退出
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

依赖

<dependency>
            <groupId>com.gblfy.dubbo</groupId>
            <artifactId>api</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

客户端配置：
applicationContext-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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
    xsi:schemaLocation="

    "
    >
  <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
  <dubbo:application name="consumer-of-helloworld-app"  />

  <!-- 用zookeeper进行注册中心化 -->
  <dubbo:registry address="zookeeper://localhost:2181"/>

  <!-- 生成远程服务代理，可以和本地bean一样使用demoService -->
  <dubbo:reference
      id="consumerService"
      interface="com.gblfy.dubbo.api.ServiceAPI"
      />

</beans>

客户端

public class ConsumerClient {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context =
                new ClassPathXmlApplicationContext("applicationContext-consumer.xml");
        context.start();
        while (true){
            Scanner scanner = new Scanner(System.in);
            String message = scanner.next();
            //获取接口
            //从spring容器中，把实现类读出来 bean id
            ServiceAPI serviceAPI = (ServiceAPI) context.getBean("consumerService");
            //message 是上面的
            //客户端发送消息--->>>服务端接收消息--->>>处理后，将结果返回--->>>客户端
            System.out.println(serviceAPI.sendMessage(message));
        }
    }
}

依赖

 <dependency>
            <groupId>com.gblfy.dubbo</groupId>
            <artifactId>api</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

启动zookeeper、服务端，客户端即可测试
