SpringBoot2.0.6集成Dubbo（零xml）
springboot集成dubbo有多种方式，这里介绍一种比较新的不用xml的方式分享给大家，用到依赖dubbo-spring-boot-starter
项目环境：win10+jdk1.8+zookeeper3.4.13+springboot2.0.6
zookeeper的安装和配置不了解的，读者大人请自行百度。
项目运行前，首先启动zookeeper的zkServer.cmd。
项目结构
spring-dubbo-test：父级项目，简单的maven项目，未用任何模板
dubbo-api：接口，简单的maven项目，未用任何模板
dubbo-consumer和dubbo-provider：消费端和服务端，新建的SpringBoot项目
父级项目的pom.xml

package com.changan.dubboconsumer.web;
import com.alibaba.dubbo.config.annotation.Reference;
import com.changan.api.DubboProviderService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
*@author zhanganbing
*@date 2018/10/31/031 22:12
*/
@RestController
@RequestMapping("/test")
public class DubboTestController {
@Reference
private DubboProviderService dubboProviderService;
@RequestMapping("/hello")
public String sayHelloToDubbo(){
return dubboProviderService.sayHello();
}
}
这里有两点值得注意：
不能使用@Autowired自动注入，而要用Dubbo提供的@Reference注解
pom.xml一定要依赖于api，即添加api的dependency

服务端DubboProviderServiceImpl代码
package com.changan.dubboprovider.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import com.changan.api.DubboProviderService;
/**
*@author zhanganbing
*@date 2018/10/31/031 22:17
*/
@Service
public class DubboProviderServiceImpl implements DubboProviderService {
@Override
public String sayHello() {
return "hello dubbo!!!!";
}
}
这里也有两点值得注意：
@Service必须使用dubbo提供的
pom.xml一定要依赖于api，即添加api的dependency
dubbo配置介绍
yml可以类比设置
运行效果
运行两个springboot项目的启动类，启动类上必须加注解@EnableDubbo
