<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<project xmlns="http://maven.apache.org/POM/4.0.0"

        </dependency>
    </dependencies>


</project>

三、需求實(shí)戰(zhàn)-代碼編寫

3.1. 創(chuàng)建公共接口

在DubboApi子模塊中創(chuàng)建調(diào)用扣庫(kù)存模塊（Stock-serv）的接口IStockService

package com.gblfy.stock.api;

public interface IStockService {
    public String reduce(Integer productId, Integer userId);
}

在DubboApi子模塊中創(chuàng)建調(diào)用產(chǎn)品（product-serv）模塊的接口

package com.gblfy.product.api;

public interface IProductService {
    public String buyProduct(Integer productId, Integer userId);
}

3.2. 扣庫(kù)存服務(wù)端編寫

在Stock-serv子模塊中實(shí)現(xiàn)接口實(shí)現(xiàn)類StockServiceimpl

package com.gblfy.service.impl;

import com.gblfy.stock.api.IStockService;
import org.apache.dubbo.config.annotation.DubboService;

@DubboService
public class StockServiceimpl implements IStockService {

    @Override
    public String reduce(Integer productId, Integer userId) {
        return "用戶編號(hào):   " + userId + "產(chǎn)品編碼:   " + productId + "減庫(kù)存1個(gè)";
    }
}

啟動(dòng)類上添加@EnableDiscoveryClient注解

package com.gblfy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableDiscoveryClient
@SpringBootApplication
public class StockApplication {
    public static void main(String[] args) {
        SpringApplication.run(StockApplication.class);
    }
}

3.3. 產(chǎn)品服務(wù)端編寫

在product-serv子模塊中實(shí)現(xiàn)接口實(shí)現(xiàn)類ProductServiceImpl

package com.gblfy.service.impl;

import com.gblfy.product.api.IProductService;
import org.apache.dubbo.config.annotation.DubboService;

@DubboService
public class ProductServiceImpl implements IProductService {

    @Override
    public String buyProduct(Integer productId, Integer userId) {
        return "用戶編號(hào):   " + userId + "產(chǎn)品編碼:   " + productId + "購(gòu)買PHONE SUCCESS";
    }
}

啟動(dòng)類添加@EnableDiscoveryClient注解

package com.gblfy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class ProductApplication {

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

3.5. 消費(fèi)端編寫

在Order-serv子模塊的啟動(dòng)類上添加@EnableDiscoveryClient開啟服務(wù)發(fā)現(xiàn)掃描

package com.gblfy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;


@SpringBootApplication
@EnableDiscoveryClient
public class OrderAppliaction {

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

創(chuàng)建一個(gè)客戶端類發(fā)起請(qǐng)求OrderController分別向扣庫(kù)存模塊和產(chǎn)品模塊發(fā)起請(qǐng)求

package com.gblfy.controller;

import com.gblfy.product.api.IProductService;
import com.gblfy.stock.api.IStockService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class OrderController {

    @DubboReference
    private IStockService stockService;
    @DubboReference
    private IProductService productService;

    @GetMapping("/order/create")
    public String createOrder(Integer productId, Integer userId) {
        //調(diào)用扣庫(kù)存模塊服務(wù)
        return stockService.reduce(productId, userId);
    }
    //http://127.0.0.1:8080/order/create?productId=2&userId=8

    @GetMapping("/buyProduct")
    public String buyProduct(Integer productId, Integer userId) {
        //調(diào)用產(chǎn)品模塊服務(wù)
        return productService.buyProduct(productId, userId);
    }
    // http://127.0.0.1:8080/buyProduct?productId=2&userId=8
}

四、需求實(shí)戰(zhàn)-配置編寫

4.1. 扣庫(kù)存服務(wù)端配置

# 應(yīng)用端口
server:
  port: 8082

# nacos服務(wù)發(fā)現(xiàn)配置
spring:
  cloud:
    nacos:
      server-addr: 127.0.0.1:8848
      discovery:
        service: stock-serv
  application:
    name: stock-serv

# Dubbo服務(wù)配置

4.2. 產(chǎn)品服務(wù)端配置

server:
  port: 8081
spring:
  cloud:
    nacos:
      server-addr: 127.0.0.1:8848
      discovery:
        service: product-serv
  application:
    name: product-serv

# Dubbo服務(wù)配置

4.3.消費(fèi)端配置

server:
  port: 8080
spring:
  application:
    name: order-serv
  cloud:
    nacos:
      discovery:
        server-addr: http://127.0.0.1:8848
      config:
        server-addr: http://127.0.0.1:8848
        
# Dubbo服務(wù)配置
