基于Apache-Dubbo结合Springboot构建开发环境

背景

阿里在经过一段时间疯狂更新后，将Dubbo逐步打造成了Apache的顶级开源项目，也就是市面上说的Apache Dubbo。Apache-Dubbo的使用方式上类似于原生，但是集成方式上会有一些区别。

准备环境

• Spring boot:
• Apache-Dubbo: 2.7.1
• Zookeeper: 3.4.10
• JDK: 1.8

相关参考资料

• Apache-Dubbo中文官网： http://dubbo.apache.org/zh-cn/
• Apache-Dubbo中文文档：http://dubbo.apache.org/zh-cn/docs/user/quick-start.html
• Apache-Dubbo Github地址：https://github.com/apache/dubbo

初始化工程

1.创建工程

命名规则随意~

2.集成pom文件

3.服务提供者接口

一个简单的加法

4.服务提供者接口实现

5.服务提供者application配置

spring.application.name=dubbo-provider-demo
dubbo.protocol.name=dubbo
dubbo.protocol.port=20881
dubbo.registry.address=zookeeper://127.0.0.1:2181

6.服务消费者消费接口

消费者做一个简单的打印输出

7.消费者启动类

8.消费者配置文件

spring.application.name=dubbo-consume-demo
dubbo.scan.base-packages=com.imooc.jiangzh.apache
dubbo.protocol.name=dubbo
dubbo.protocol.port=20882
dubbo.registry.address=zookeeper://114.67.92.118:2181

最终效果
