优化以下代码： if (supplierGoodsDTO.getDeliveryWay() == DeliveryWayEnum.PLATFORM_DELIVERY) { //判断商品类目 if (!CollectionUtils.isEmpty(goodsCategoryId)) { if (goodsCategoryId.contains(goodsDTO.getGoodsCategoryId())) { appGoodsVO.setIsOverBought(true); } else { //判断商品是否存在买多返多 if (goodsId.contains(goodsDTO.getId())) { appGoodsVO.setIsOverBought(true); } else { appGoodsVO.setIsOverBought(false); } } } else { //判断商品是否存在买多返多 if (goodsId.contains(goodsDTO.getId())) { appGoodsVO.setIsOverBought(true); } else { appGoodsVO.setIsOverBought(false); } } }

优化后的代码如下：

if (supplierGoodsDTO.getDeliveryWay() == DeliveryWayEnum.PLATFORM_DELIVERY) {
    boolean isOverBought = false;
    if (CollectionUtils.isEmpty(goodsCategoryId) || goodsCategoryId.contains(goodsDTO.getGoodsCategoryId()) || goodsId.contains(goodsDTO.getId())) {
        isOverBought = true;
    }
    appGoodsVO.setIsOverBought(isOverBought);
}

优化思路：

1. 将 `appGoodsVO.setIsOverBought()` 的设置操作放到一个变量中，避免重复代码；
2. 判断条件合并，将原来的嵌套判断改为一层判断，简化逻辑。
