1.数据结构

List<Map<String,Object>> mapList = Lists.newArrayList();Long originalOrderId = returnObj.getOriginalOrderId();List<Long> orderIdList = Lists.newArrayList();orderIdList.add(originalOrderId);List<Item> itemList = itemService.listByOrderIdList(orderIdList);for (Item item : itemList) {Map<String,Object> map = Maps.newLinkedHashMap();if(item != null){Product product = item.getProduct();if(product == null){product = productService.get(item.getProductId());}if(product != null){map.put("productName", product.getName());}List<SpecJsonItem> specList = item.getSpecItemList();if(CollectionUtils.isEmpty(specList)){specList = JSON.parseArray(item.getSpecJson(), SpecJsonItem.class);}if(CollectionUtils.isNotEmpty(specList)){StringBuffer spec = new StringBuffer();for (SpecJsonItem specJsonItem : specList) {spec.append(specJsonItem.getName()).append(":").append(specJsonItem.getValue()).append(" ");}map.put("spec", spec);}}else{item = new Item();}map.put("item", item);mapList.add(map);}model.addAttribute("mapList", mapList);

2.前端页面循环

<#list mapList as map><tr class="product_${map_index}"><td>商品名称:</td><td>${map['productName']}</td><td rowspan="2">商品图片:</td><td rowspan="2"><img src="${imageDomain}/${map['item'].pic}@200w"></td></tr><tr class="product_${map_index}"><td>购买规格:</td><td>${map['spec']}</td></tr><tr class="product_${map_index}"><td>购买价格:</td><td>${map['item'].price}</td><td>购买数量:</td><td>${map['item'].quantity}</td></tr></#list>
