springBoot+dubbo服务提供者的使用
zookeeper安装

• 基于全注解方式

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

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
   

4. 引用服务提供者提供的接口
   

5. 访问DubboTestController

• 基于XML方式

  1. 使用上面的pom.xml文件

  2. 创建xml配置文件
     

     
     <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());
         }
     }
