按照服务：

SpringCould-product_server 

创建 order_server 服务  只需要改变名字 其他的都一样

一、实现商品服务的接口

Order类

package com.sxpcwlkj.order_server.entity;
import java.math.BigDecimal;
public class Order {
    private int id;
    //订单号
    private String codeNumber;
    //用户id
    private int memberId;
    //商品Id
    private int  produceId;
    private String name;
    //商品价格
    private BigDecimal pice;
    //库存
    private int  num;
    public Order() {
    }
    public Order(int id, String codeNumber, int memberId, int produceId, String name, BigDecimal pice, int num) {
        this.id = id;
        this.codeNumber = codeNumber;
        this.memberId = memberId;
        this.produceId = produceId;
        this.name = name;
        this.pice = pice;
        this.num = num;
    }
    public int getId() {
        return id;
    }
    public int getProduceId() {
        return produceId;
    }
    public void setProduceId(int produceId) {
        this.produceId = produceId;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getCodeNumber() {
        return codeNumber;
    }
    public void setCodeNumber(String codeNumber) {
        this.codeNumber = codeNumber;
    }
    public int getMemberId() {
        return memberId;
    }
    public void setMemberId(int memberId) {
        this.memberId = memberId;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public BigDecimal getPice() {
        return pice;
    }
    public void setPice(BigDecimal pice) {
        this.pice = pice;
    }
    public int getNum() {
        return num;
    }
    public void setNum(int num) {
        this.num = num;
    }
}

OrderService类

package com.sxpcwlkj.order_server.service;
import com.sxpcwlkj.order_server.entity.Order;
import org.aspectj.weaver.ast.Or;
public interface OrderService {
    /**
     * 创建订单
     * @return
     */
    Order addOrder(int memberId ,int produceId);
    /**
     * 查询订单
     * @param id
     * @return
     */
    Order selectById(int id);
}

OrderServiceImpl类

package com.sxpcwlkj.order_server.service.impl;
import com.sxpcwlkj.order_server.entity.Order;
import com.sxpcwlkj.order_server.service.OrderService;
import org.springframework.stereotype.Service;
import java.math.BigDecimal;
import java.util.UUID;
@Service
public class OrderServiceImpl implements OrderService {
    @Override
    public Order addOrder(int memberId ,int produceId) {
        Order  order =new Order();
        order.setCodeNumber(UUID.randomUUID().toString()); //订单号
        order.setMemberId(memberId);                       //用户Id
        order.setProduceId(produceId);                     //商品Id
        //    准备从  商品服务 获取数据  ：更具商品id查询商品详情
        //    /api/v1/product/selectById?id=1
        order.setName("");                                 //商品名称
        order.setPice(new BigDecimal(00));             //商品价格
        order.setNum(0);                                   //商品库存
        return order;
    }
    @Override
    public Order selectById(int id) {
        return null;
    }
}

OrderController类

package com.sxpcwlkj.order_server.controller;
import com.sxpcwlkj.order_server.service.OrderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/api/v1/order")
public class OrderController {
    @Autowired
    private OrderService  orderService;
    /**
     * 用户下单
     * @param memberId   用户Id
     * @param produceId  商品Id
     * @return
     */
    @RequestMapping("addOrder")
    public Object  setlstOrder(int memberId ,int produceId){
       return   orderService.addOrder(memberId,produceId);
    }
}

/api/v1/order/addOrder?memberId=1&productId=1
