二、项目介绍
项目描述：这是一个基于SpringBoot+Vue框架开发的服装商城系统。首先，这是一个前后端分离的项目，代码简洁规范，注释说明详细，易于理解和学习。其次，这项目功能丰富，具有一个服装商城系统该有的所有功能。
项目功能：此项目分为两个角色：普通用户和管理员。普通用户有登录注册、浏览商品信息、管理个人购物车信息、提交订单、评价订单、管理个人地址信息、管理个人订单信息、管理个人评价信息等等功能。管理员有登录、查看数据统计信息、管理所有用户信息、管理所有商品信息、管理所有商品分类信息、管理所有订单信息、管理所有评价信息等等功能。
应用技术：SpringBoot + Vue3.0 + MySQL + MyBatis + Redis + ElementUI-Plus + Vite
运行环境：IntelliJ IDEA2019.3.5 + MySQL5.7 + Redis5.0.5 + JDK1.8 + Maven3.6.3 + Node14.16.1 + Visual Studio Code（以上工具在项目压缩包中都自带）

四、主要代码
1.提交订单代码
/**
* 提交订单操作
* @param orderDTO
* @return
*/
@Override
public ResponseDTO<Boolean> submitOrder(OrderDTO orderDTO) {
if(CommonUtil.isEmpty(orderDTO.getUserId())) {
return ResponseDTO.errorByMsg(CodeMsg.DATA_ERROR);
}
// 进行统一表单验证
CodeMsg validate = ValidateEntityUtil.validate(orderDTO);
if (!validate.getCode().equals(CodeMsg.SUCCESS.getCode())) {
return ResponseDTO.errorByMsg(validate);
}
User user = userMapper.selectByPrimaryKey(orderDTO.getUserId());
if(user == null) {
return ResponseDTO.errorByMsg(CodeMsg.USER_NOT_EXIST);
}
// 查出购物车数据
CartExample cartExample = new CartExample();
cartExample.createCriteria().andUserIdEqualTo(orderDTO.getUserId()).andIdIn(orderDTO.getCartIdList());
List<Cart> cartList = cartMapper.selectByExample(cartExample);
for(Cart cart : cartList) {
Product product = productMapper.selectByPrimaryKey(cart.getProductId());
if(product == null) {
CodeMsg codeMsg = CodeMsg.PRODUCT_NOT_EXIST;
codeMsg.setMsg("有商品信息已经不存在，请刷新页面！");
return ResponseDTO.errorByMsg(codeMsg);
}
Stock stock = stockMapper.selectByPrimaryKey(cart.getStockId());
if(stock == null) {
CodeMsg codeMsg = CodeMsg.STOCK_NOT_EXIST;
codeMsg.setMsg("商品[" + product.getName() + "]的规格已经不存在，请删除商品重新选择！");
return ResponseDTO.errorByMsg(codeMsg);
}
if(cart.getQuantity() > stock.getNum()) {
CodeMsg codeMsg = CodeMsg.STOCK_NUM_ERROR;
codeMsg.setMsg("商品[" + product.getName() + "]的库存不足，请刷新页面更新库存信息！");
return ResponseDTO.errorByMsg(codeMsg);
}
}
BigDecimal totalPrice = new BigDecimal("0");
Order order = CopyUtil.copy(orderDTO, Order.class);
order.setId(UuidUtil.getShortUuid());
order.setCreateTime(new Date());
// 减库存加销量
for(Cart cart : cartList) {
Product product = productMapper.selectByPrimaryKey(cart.getProductId());
product.setSellNum(product.getSellNum() + cart.getQuantity());
Stock stock = stockMapper.selectByPrimaryKey(cart.getStockId());
stock.setNum(stock.getNum() - cart.getQuantity());
if(productMapper.updateByPrimaryKeySelective(product) == 0) {
throw new RuntimeException(CodeMsg.ORDER_ADD_ERROR.getMsg());
}
if(stockMapper.updateByPrimaryKeySelective(stock) == 0) {
throw new RuntimeException(CodeMsg.ORDER_ADD_ERROR.getMsg());
}
totalPrice = totalPrice.add(product.getPrice().multiply(new BigDecimal(cart.getQuantity())));
OrderItem orderItem = new OrderItem();
orderItem.setId(UuidUtil.getShortUuid());
orderItem.setOrderId(order.getId());
orderItem.setProductPrice(product.getPrice());
orderItem.setProductName(product.getName());
orderItem.setProductId(product.getId());
orderItem.setQuantity(cart.getQuantity());
orderItem.setSumPrice(new BigDecimal(cart.getQuantity()).multiply(product.getPrice()));
orderItem.setProductScale(stock.getName());
orderItem.setStockId(stock.getId());
// 获取商品封面图片
PictureExample pictureExample = new PictureExample();
pictureExample.createCriteria().andProductIdEqualTo(product.getId()).andSortEqualTo(1);
List<Picture> pictureList = pictureMapper.selectByExample(pictureExample);
if(pictureList.size() > 0) {
orderItem.setProductPhoto(pictureList.get(0).getPhoto());
}
if(orderItemMapper.insertSelective(orderItem) == 0) {
throw new RuntimeException(CodeMsg.ORDER_ADD_ERROR.getMsg());
}
}
order.setTotalPrice(totalPrice);
order.setState(OrderStateEnum.WAIT.getCode());
// 清空购物车数据
cartMapper.deleteByExample(cartExample);
if(orderMapper.insertSelective(order) == 0) {
throw new RuntimeException(CodeMsg.ORDER_ADD_ERROR.getMsg());
}
return ResponseDTO.successByMsg(true, "下单成功！");
}
2.添加商品代码
/**
* 保存商品信息
* @param productDTO
* @return
*/
@Override
public ResponseDTO<Boolean> saveProduct(ProductDTO productDTO) {
// 进行统一表单验证
CodeMsg validate = ValidateEntityUtil.validate(productDTO);
if (!validate.getCode().equals(CodeMsg.SUCCESS.getCode())) {
return ResponseDTO.errorByMsg(validate);
}
Product product = CopyUtil.copy(productDTO, Product.class);
if(CommonUtil.isEmpty(product.getId())) {
// 添加操作
product.setId(UuidUtil.getShortUuid());
product.setCreateTime(new Date());
if(productMapper.insertSelective(product) == 0) {
return ResponseDTO.errorByMsg(CodeMsg.PRODUCT_ADD_ERROR);
}
} else {
// 修改操作
if(productMapper.updateByPrimaryKeySelective(product) == 0) {
return ResponseDTO.errorByMsg(CodeMsg.PRODUCT_EDIT_ERROR);
}
// 图集数据落地
batchInsertPicture(productDTO.getPhotoList(), product.getId());
}
return ResponseDTO.successByMsg(true, "保存成功！");
}
3.查询购物车代码
/**
* 查询购物车信息
* @param cartDTO
* @return
*/
@Override
public ResponseDTO<List<CartDTO>> getCartList(CartDTO cartDTO) {
if(CommonUtil.isEmpty(cartDTO.getUserId()) && CommonUtil.isEmpty(cartDTO.getId())) {
return ResponseDTO.errorByMsg(CodeMsg.DATA_ERROR);
}
CartExample cartExample = new CartExample();
CartExample.Criteria criteria = cartExample.createCriteria();
if(!CommonUtil.isEmpty(cartDTO.getUserId())) {
criteria.andUserIdEqualTo(cartDTO.getUserId());
}
if(!CommonUtil.isEmpty(cartDTO.getId())) {
criteria.andIdIn(Arrays.asList(cartDTO.getId().split(";")));
// where id in (?,?)
}
List<Cart> cartList = cartMapper.selectByExample(cartExample);
List<CartDTO> cartDTOList = CopyUtil.copyList(cartList, CartDTO.class);
for(CartDTO cart : cartDTOList) {
Product product = productMapper.selectByPrimaryKey(cart.getProductId());
ProductDTO productDTO = CopyUtil.copy(Optional.ofNullable(product).orElse(new Product()), ProductDTO.class);
PictureExample pictureExample = new PictureExample();
pictureExample.createCriteria().andProductIdEqualTo(productDTO.getId());
pictureExample.setOrderByClause("sort asc, id asc");
List<Picture> pictureList = pictureMapper.selectByExample(pictureExample);
List<String> photoList = pictureList.stream().map(Picture::getPhoto).collect(Collectors.toList());
productDTO.setPhotoList(photoList);
cart.setProductDTO(productDTO);
Stock stock = stockMapper.selectByPrimaryKey(cart.getStockId());
cart.setStockDTO(CopyUtil.copy(Optional.ofNullable(stock).orElse(new Stock()), StockDTO.class));
}
return ResponseDTO.success(cartDTOList);
}
