写在前面：

关于dubbo的原理和springboot以及mybatis的介绍，这里就不说了，想要了解的，可以百度。

主要介绍：

我这里主要分为三个项目，dubbo-interface-api 用来定义接口；dubbo-provider-api 生产者，dubbo-consumer-api 消费者。

其中，生产者和消费者分别需要引用dubbo-interface-api接口项目,版本信息如下：

spring boot	2.0.3
dubbo	2.6.2
mysql	5.1.46
mybatis-spring-boot	1.3.2
zookeeper	3.4.9

下面分别给出关键代码以及依赖：

接口定义

package com.example.dubbo.order;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/dubbo/order")
public interface IOrderService {

	@Path("/getOrders")
	@GET
	@Consumes("application/json; charset=UTF-8")
	@Produces("application/json; charset=UTF-8")
	public String getOrderList();
}

实体类定义

package com.example.dubbo.dto;

public class Order {

	private String id;
	
	private String name;

	public String getId() {
		return id;
	}

	public void setId(String id) {

mapper接口类定义：

package com.example.dubbo.mapper;

import java.util.List;

import com.example.dubbo.dto.Order;

public interface OrderMapper {
	
	public List<Order> selectOrders();
}

实现类定义：

package com.example.dubbo.service;

import java.util.List;

import javax.annotation.Resource;

import com.alibaba.fastjson.JSONObject;
import com.example.dubbo.dto.Order;
import com.example.dubbo.mapper.OrderMapper;
import com.example.dubbo.order.IOrderService;

public class OrderServiceImpl implements IOrderService{

	@Resource
	private OrderMapper orderMapper;
	
	@Override
	public String getOrderList() {
		List<Order> orders = orderMapper.selectOrders();
		String json = JSONObject.toJSONString(orders);
		return json;
	}

}

OrderMapper.xml定义

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.example.dubbo.mapper.OrderMapper">
	<select id="selectOrders" resultType="com.example.dubbo.dto.Order">
		select id as id,name as name
		from tbl_order
	</select>
</mapper>

启动类加两行注解：

package com.example.dubbo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

@ImportResource(locations="classpath:provider.xml")
@SpringBootApplication
@MapperScan("com.example.dubbo.mapper")
public class DubboProviderApiApplication {

	public static void main(String[] args) {
		SpringApplication.run(DubboProviderApiApplication.class, args);
	}

}

@ImportResource 为provider.xml的位置

@MapperScan 为mapper接口定义的包名

项目目录如下：

至此生产者已经搭建完毕，启动服务观察是否注册成功。(这里可以看我另一篇关于dubbo服务搭建的博文，那里有关于dubbo-admin的搭建）

下面介绍消费者的搭建

1.如果是rest请求，则直接请求http://ip+rest端口(参见provider.xml配置)+请求路径(参考dubbo-interface-api接口类中@Path的定义)

2.如果是通过dubbo服务请求，则需要一下配置

dubbo-consumer-api

application.properties:

OrderController.java定义

package com.example.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 com.example.dubbo.order.IOrderService;

@Controller
public class OrderController {
	
	@Reference(version = "1.0.0",timeout = 3000,check = false)
	private IOrderService orderService;
	
	@RequestMapping("/getOrders")
	@ResponseBody
	public String getOrderList() {
		String result = orderService.getOrderList();
		return result;
	}

}

注意：

version:需与provider.xml中version对应，timeout为请求超时时间，check为启动时是否检查生产者在线

启动类修改：

package com.example.dubbo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

@ImportResource(locations="classpath:consumer.xml")
@SpringBootApplication
public class DubboConsumerApApplication {

	public static void main(String[] args) {
		SpringApplication.run(DubboConsumerApApplication.class, args);
	}

}

至此，消费者完毕，如需调用，请求http://ip+配置端口+请求路径，例如，例子中给出的代码请求路径为：http://127.0.0.1:12007/dubbo/getOrders
