按照服务：
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
