*  ## 基于全注解方式 ##

1.  pom.xml文件(引入[springBoot+dubbo服务提供者的使用][springBoot_dubbo]里创建的接口项目和dubbo依赖)

        </project>
2.  application.properties配置文件
    
    > \#提供方应用信息，用于计算依赖关系  
    > dubbo.application.name=dubboConsumer  
    > \#使用zookeeper注册中心  
    > dubbo.registry.address=zookeeper://127.0.0.1:2181

3.  springBoot启动类添加@EnableDubbo注解  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 1]
4.  引用服务提供者提供的接口

5.  访问DubboTestController  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 3]

--------------------

*  ## 基于XML方式 ##
    
    1.  使用上面的pom.xml文件
    2.  创建xml配置文件  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 4]
        
            <?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">
            
                
                <dubbo:application name="dubboConsumer"/>
            
                
                <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
            
                
                <dubbo:reference interface="com.dubbo.service.DubboTestService" id="dubboTestService" group="test" version="1.0.0"/>
            </beans>
    3.  执行
        
            import com.dubbo.service.DubboTestService;
            import org.springframework.context.support.ClassPathXmlApplicationContext;
            
            
            public class ConsumerApplication { 
            
                public static void main(String[] args) { 
                   
                    ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("consumer.xml");
                    DubboTestService dubboTestService = context.getBean("dubboTestService", DubboTestService.class);
                    System.out.println(dubboTestService.getTestResult());
                }
            }
