dubbo——dubbo在springboot中的使用

1，引入依赖

<!-- Spring Boot Dubbo 依赖 -->
<dependency>
<groupId>io.dubbo.springboot</groupId>
	<artifactId>spring-boot-starter-dubbo</artifactId>
	<version>1.0.0</version>
</dependency>

2，接口(dubbo-interface)

新建公用的接口项目dubbo-interface，打成jar包。

package demo.dubbo.service;

import java.util.List;

public interface DubboTestService {

	String test1(String str);
	
	List<String> test2();
}

服务提供方dubbo-provider和服务消费方dubbo-consume的pom.xml引入接口依赖

<!-- 接口 -->
<dependency>
    <groupId>demo.dubbo</groupId>
    <artifactId>dubbo-interface</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

2，服务提供方(dubbo-provider)

①实现接口，注册服务

实现dubbo-interface的接口的实现类加**@Service**注解，

注意包是dubbo里面的（import com.alibaba.dubbo.config.annotation.Service;）

package demo.dubbo.service;

import java.util.ArrayList;
import java.util.List;
import com.alibaba.dubbo.config.annotation.Service;

@Service
public class DubboTestServiceImpl implements DubboTestService{

	@Override
	public String test1(String str) {
		// TODO Auto-generated method stub
		System.out.println("调用服务test1方法，参数是：" + str);
		return "hello dubbo";
	}

	@Override
	public List<String> test2() {
		// TODO Auto-generated method stub
		System.out.println("调用服务test2方法" );
		List<String> list = new ArrayList<>();
		list.add("hello");
		list.add("dubbo");
		return list;
	}

}

②application.yml关于dubbo的配置

server:
  port: 8080
  contextPath: /
  
spring: 
  dubbo: 
      application:                    #应用配置
          name: provider              #应用名字
      scan: demo.dubbo.service        #服务包名 service包名
      protocol:                       #协议配置 只需要服务提供方配置
          name: dubbo                 #协议名称
          port: 20880                 #协议端口号
      registry:                       #注册中心地址配置
          address: zookeeper://10.1.255.102:2181

3，服务消费方(dubbo-consume)

①通过**@Reference**远程注入

注意包名也是dubbo里面的（import com.alibaba.dubbo.config.annotation.Reference；）

package demo.dubbo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.alibaba.dubbo.config.annotation.Reference;
import demo.dubbo.service.DubboTestService;

@Controller
@RequestMapping("/")
public class DubboTestController {
	
	@Reference
	private DubboTestService dubboTestService;
	
	@RequestMapping("/test1")
	@ResponseBody
	public String test1() {
		return dubboTestService.test1("test");
	}
	
	@RequestMapping("/test2")
	@ResponseBody
	public Object test2() {
		return dubboTestService.test2();
	}
}
