springBoot+dubbo服务提供者的使用
zookeeper安装

基于全注解方式

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)

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
springBoot启动类添加@EnableDubbo注解
引用服务提供者提供的接口
访问DubboTestController

基于XML方式

使用上面的pom.xml文件

创建xml配置文件
在这里插入图片描述

<?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">
    <!-- 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"/>
    <!-- 将该接口暴露到dubbo中 -->
    <dubbo:reference interface="com.dubbo.service.DubboTestService" id="dubboTestService" group="test" version="1.0.0"/>
</beans>

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());
            }
        }
