springmvc开发订单类api接口

在接手到这个项目时，我对订单只是模糊的概念，淘宝的购物流程我想在坐的各位都知道，但是具体到开发的时候，考虑的细节那是很多的，如订单状态的判断，支付前的检查等等，下面我就说说订单的业务流程： 首先声明一个订单请求类，用来从客户端传来订单的请求信息 - 订单请求类

public class AddMemberOrderPaymentItemsRequest { private int orderId; private int memberId; private List<PaymentData> orderPayments; public int getOrderId() { return orderId; } public void setOrderId(int orderId) { this.orderId = orderId; } public int getMemberId() { return memberId; } public void setMemberId(int memberId) { this.memberId = memberId; } public List<PaymentData> getOrderPayments() { return orderPayments; } public void setOrderPayments(List<PaymentData> orderPayments) { this.orderPayments = orderPayments; } } 订单的支付数据类 public class OrderPaymentData { private String orderSn; private String paymentType; private Integer paymentTypeValue; private Integer paymentTypeFee; private Long paymentTime; private String notifyId; private Integer status; private String tradeNo; private String password; private Integer paymentSourceId; private String remark; public String getOrderSn() { return orderSn; } public void setOrderSn(String orderSn) { this.orderSn = orderSn; } public String getPaymentType() { return paymentType; } public void setPaymentType(String paymentType) { this.paymentType = paymentType; } public Integer getPaymentTypeValue() { return paymentTypeValue; } public void setPaymentTypeValue(Integer paymentTypeValue) { this.paymentTypeValue = paymentTypeValue; } public Integer getPaymentTypeFee() { return paymentTypeFee; } public void setPaymentTypeFee(Integer paymentTypeFee) { this.paymentTypeFee = paymentTypeFee;

下面开始进行业务处理 首先我们通过order的id取到数据库中的订单记录判断是否为空

if (!memberOrderRecord.getMemberId().equals( addMemberOrderPaymentItemsRequest.getMemberId()) || !memberOrderRecord.getId().equals( addMemberOrderPaymentItemsRequest.getOrderId())) { throw new OpenapiException("member order not match", OrderErrorCode.ERR_API_APP_MEMBER_ORDER_NOT_MATCH); }

接着我们取出订单记录中的订单支付类，然后判断支付方式是否存在，如果为空，则添加订单的支付方式，否则报出异常，订单已有支付方式

List<MemberOrderPaymentList> memberOrderPaymentLists = memberOrderRecord .getOrderPaymentLists(); if ((memberOrderPaymentLists == null || memberOrderPaymentLists .isEmpty())) { // 订单支付方式没有 if (addMemberOrderPaymentItemsRequest == null || addMemberOrderPaymentItemsRequest.getOrderPayments() == null || addMemberOrderPaymentItemsRequest.getOrderPayments() .isEmpty()) { throw new OpenapiException( "member order payment items not set", OrderErrorCode.ERR_API_APP_MEMBER_ORDER_PAYMENT_TYPE_NOT_SET); } else { / 添加订单支付方式 List<OrderPaymentData> orderPaymentDatas = Lists.newArrayList(); List<PaymentData> paymentDatas = addMemberOrderPaymentItemsRequest .getOrderPayments(); OrderDataUtils.setOrderPaymentData(orderPaymentDatas, paymentDatas); /** public static void setOrderPaymentData( List<OrderPaymentData> orderPaymentDatas, List<PaymentData> paymentDatas) { for (PaymentData paymentData : paymentDatas) { OrderPaymentData orderPaymentData = new OrderPaymentData(); orderPaymentData.setPaymentType(paymentData.getPaymentType()); orderPaymentData.setPaymentTypeFee(PaymentConvertUtils .convertFeeStringToInt(paymentData.getPaymentFee())); orderPaymentData.setPaymentTypeValue(PaymentConvertUtils .convertCreditStringToInt(paymentData.getPaymentValue())); orderPaymentData .setStatus(OrderConstants.ORDER_PAYMENT_STATUS_WAIT_PAY); orderPaymentData.setPassword(paymentData.getPassword()); orderPaymentData.setPaymentSourceId(paymentData .getPaymentSourceId()); orderPaymentData.setRemark(paymentData.getRemark()); orderPaymentDatas.add(orderPaymentData); } } **/ try { memberOrderRecordService.addOrderPaymentItems( orderPaymentDatas, memberOrderRecord, false); } catch (OrderException e) { logger.error("error", e); throw new OpenapiException( "member order add payment items failed", OrderErrorCode.ERR_API_APP_MEMBER_ORDER_ADD_PAYMENT_TYPES_FAILED); } } } else { // 订单已有支付方式 if (addMemberOrderPaymentItemsRequest != null && addMemberOrderPaymentItemsRequest.getOrderPayments() != null && !addMemberOrderPaymentItemsRequest.getOrderPayments() .isEmpty()) { throw new OpenapiException( "member order payment items has been set", OrderErrorCode.ERR_API_APP_MEMBER_ORDER_PAYMENT_TYPE_HAS_BEEN_SET); } } 其中涉及的方法在service层 在其中，订单的值传过来后，赋值给订单支付类，订单支付类的值填充好后再加入到订单记录类中，保存订单记录类到数据库 @Override @Transactional public boolean addOrderPaymentItems( List<OrderPaymentData> orderPaymentDatas, MemberOrderRecord orderRecord, boolean allowSamePaymentType) throws OrderException { // 订单支付 if (orderPaymentDatas != null && !orderPaymentDatas.isEmpty()) { List<MemberOrderPaymentList> orderPaymentLists = createOrderPaymentItems( orderPaymentDatas, orderRecord, allowSamePaymentType); if (orderRecord.getOrderPaymentLists() == null) { orderRecord.setOrderPaymentLists(orderPaymentLists); } else { orderRecord.getOrderPaymentLists().addAll(orderPaymentLists); } Integer allFee = orderRecord.getItemsTotalFee(); Integer allValue = orderRecord.getItemsTotalValue(); Integer paymentFee = orderRecord.getTotalPaymentFee(); Integer paymentValue = orderRecord.getTotalPaymentValue(); // 支付费用不能小于商品总价，可以大于。 if ((allFee != null && (paymentFee == null || paymentFee < allFee)) || (allValue != null && (paymentValue == null || paymentValue < allValue))) { throw new OrderException("订单支付金额小于商品总价"); } save(orderRecord); return true; } else { throw new OrderException("订单支付方式为空"); } } private List<MemberOrderPaymentList> createOrderPaymentItems( List<OrderPaymentData> orderPaymentDatas, MemberOrderRecord orderRecord, boolean allowSamePaymentType) throws OrderException { OrderHelper orderHelper = orderHelperMap.get(orderRecord .getOrderHelperType()); Set<String> orderPaymentTypes = Sets.newHashSet(); if (orderPaymentDatas != null && !orderPaymentDatas.isEmpty()) { List<MemberOrderPaymentList> orderPaymentLists = Lists .newArrayList(); for (OrderPaymentData orderPaymentData : orderPaymentDatas) { if ((orderPaymentData.getPaymentTypeFee() == null || orderPaymentData .getPaymentTypeFee() == 0) && (orderPaymentData.getPaymentTypeValue() == null || orderPaymentData .getPaymentTypeValue() == 0)) { // 支付的fee和value都为0则忽略此支付方式的数据 continue; } String paymentType = orderPaymentData.getPaymentType(); if (!allowSamePaymentType) { Integer sourceId = orderPaymentData.getPaymentSourceId(); String key; if (sourceId != null) { // 使用paymentType+sourceId的方式判断是否重复 key = paymentType + sourceId; } else { key = paymentType; } if (orderPaymentTypes.contains(key)) { throw new OrderException("订单支付方式重复", -1); } else { orderPaymentTypes.add(key); } } MemberOrderPaymentList orderPaymentList = new MemberOrderPaymentList(); orderPaymentList.setNotifyId(orderPaymentData.getNotifyId()); orderPaymentList.setOrderRecord(orderRecord); orderPaymentList.setOrderSn(orderRecord.getOrderSn()); orderPaymentList.setPaymentSn(orderHelper .generatePaymentSn(paymentType)); orderPaymentList.setPaymentTime(orderPaymentData .getPaymentTime()); orderPaymentList.setPaymentType(paymentType); // 默认情况source与type相同 orderPaymentList.setPaymentSource(paymentType); orderPaymentList.setPaymentTypeFee(orderPaymentData .getPaymentTypeFee()); orderPaymentList.setPaymentTypeValue(orderPaymentData .getPaymentTypeValue()); orderPaymentList.setStatus(orderPaymentData.getStatus()); orderPaymentList.setTradeNo(orderPaymentData.getTradeNo()); ConfigPaymentType configPaymentType = configPaymentTypeService .find(paymentType); orderPaymentList.setPriority(configPaymentType.getPriority()); orderPaymentList.setCanInvoice(configPaymentType .getCanInvoice()); orderPaymentList.setPassword(orderPaymentData.getPassword()); orderPaymentList.setPaymentSourceId(orderPaymentData .getPaymentSourceId()); orderPaymentList.setRemark(orderPaymentData.getRemark()); checkAndExchangePaymentTypeVaueFee(orderRecord.getOrderType() .getType(), orderPaymentList); checkPaymentItem(orderPaymentList); orderPaymentLists.add(orderPaymentList); } return orderPaymentLists; } else { return null; } } 订单支付controller作为返回的api 其中的bodyToObject（）方法是将请求来的json数据进行转化成AddMemberOrderPaymentItemsRequest 对象 // 支付会员订单 @RequestMapping(value = "/{orderId}/payments", method = RequestMethod.POST, produces = "application/json;charset=UTF-8, text/plain;charset=UTF-8") public Object addOrderPayments(@PathVariable Integer orderId, HttpServletRequest request, HttpServletResponse response) { AddMemberOrderPaymentItemsRequest addMemberOrderPaymentItemsRequest = bodyToObject( AddMemberOrderPaymentItemsRequest.class, request); if (addMemberOrderPaymentItemsRequest == null) { return HttpErrorObject .constructHttpErrorObject(OrderErrorCode.ERR_API_APP_ORDER_ADD_PAYMENTS_REQUEST_NULL); } return orderService.addOrderPayments(orderId, addMemberOrderPaymentItemsRequest); }

对于订单业务的理解，还需要多结合业务场景需求去完成，这儿只是订单支付的一个小程序 希望对你们有所帮助！
