## 一.编写消费者 ##

1.新建Maven项目,编写接口和实现类

2.在pom中加入依赖

<dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring</artifactId>
          <version>2.5.6</version>
        </dependency>
    
        
        <dependency>
          <groupId>com.alibaba</groupId>
          <artifactId>dubbo</artifactId>
          <version>2.4.10</version>
          <exclusions>
            <exclusion>
              <groupId>org.springframework</groupId>
              <artifactId>spring</artifactId>
            </exclusion>
          </exclusions>
        </dependency>
    
        
        <dependency>
          <groupId>com.101tec</groupId>
          <artifactId>zkclient</artifactId>
          <version>0.4</version>
        </dependency>

3.编写接口SayHellow，不用编写实现类

4.在resources目录新建spring配置文件applicationContext.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="tiglle-dubbo-consumer"/>
    
    
        
        <dubbo:registry id="zk" address="tianxiaolin.cn:2181" protocol="zookeeper"/>
    
        
        <dubbo:consumer registry="zk"/>
    
        
        <dubbo:reference id="sayHellow" interface="com.tiglle.service.SayHellow"/>
        
        
        
    
    
    </beans>

5.编写main方法，使用消费者

public static void main( String[] args ) {
            //加载spring容器
            /* 此方法不支持dubbo的配置 BeanFactory context = new XmlBeanFactory(new ClassPathResource("applicationContext.xml")); */
            ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationContext.xml" });
            //获取生产者实例
            SayHellow sayHellow = (SayHellow) context.getBean("sayHellow");
            String str = sayHellow.sayHellow("世界");
            System.out.print(str);
        }

6.运行程序

你好:世界
    Process finished with exit code 0

消费者调用成功
