是不是你们要找的！是不是你们要找的！是不是你们要找的！

先看效果：

1.word模板格式

2.模板位置

3.需要的依赖

        <!--POI-TL实现数据导出到word模板--><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.8.0.M2</version></dependency><dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.9.1</version></dependency><!--支持Zip--><dependency><groupId>net.lingala.zip4j</groupId><artifactId>zip4j</artifactId><version>2.11.5</version></dependency>

4.直上代码

    @Overridepublic Result exportReportAAndF1List(HttpServletResponse response,List<Integer> ids) throws Exception {List<Map<String, Object>> arrayMap = new ArrayList<>();for(Integer sonId:ids) {//导出A 单个导出TestRecord testRecord = testRecordMapper.selectById(sonId);List<VehicleParts> vehiclePartsList = vehiclePartsMapper.selectList(new LambdaQueryWrapper<VehicleParts>().eq(VehicleParts::getModelId,testRecord.getModelId()));Map<Integer, VehicleParts> vehiclePartsMap = vehiclePartsList.stream().collect(Collectors.toMap(VehicleParts::getId, vehicleParts -> vehicleParts));JSONObject vehicle = new JSONObject();Unit unit = null;if (StringUtils.isNotBlank(testRecord.getVehicleInfo())) {vehicle = JSONObject.parseObject(testRecord.getVehicleInfo());Integer unitId = vehicle.getInteger("unitId");if (unitId != null) {unit = unitMapper.selectById(unitId);}}// 1 设置编码格式、文件名称response.setCharacterEncoding("utf-8");Map<String, Object> map = new HashMap<>();// 1.基本属性填充map.put("fName", "F" + testRecord.getModelId());map.put("fileName", Optional.ofNullable(testRecord.getFileName()).orElse("--"));map.put("modelName", Optional.ofNullable(testRecord.getModelName()).orElse("--")); //Optional.ofNullable().orElse("--")map.put("powerHours", (int) Math.floor(Optional.ofNullable(vehicle.getDouble("powerHours")).orElse(0.0)));map.put("plateNumber", Optional.ofNullable(vehicle.get("plateNumber")).orElse("--"));map.put("powerPackWorkingHours", (int) Math.floor(Optional.ofNullable(vehicle.getDouble("powerPackWorkingHours")).orElse(0.0)));if (!unit.getParent().equals(0)) {Unit unitFather = unitMapper.selectById(unit.getParent());map.put("unitName", Optional.ofNullable(unitFather.getUnitName() + "/" + unit.getUnitName()).orElse("--"));} else {map.put("unitName", Optional.ofNullable(unit.getUnitName()).orElse("--"));}map.put("powerPackYieldHours", (int) Math.floor(Optional.ofNullable(vehicle.getDouble("powerPackYieldHours")).orElse(0.0)));map.put("factoryDate", Optional.ofNullable(vehicle.get("factoryDate")).orElse("--"));map.put("taskPayloadWorkingHours", (int) Math.floor(Optional.ofNullable(vehicle.getDouble("taskPayloadWorkingHours")).orElse(0.0)));map.put("mileage", (int) Math.floor(Optional.ofNullable(testRecord.getMileage()).orElse(0.0)));map.put("createTime", Optional.ofNullable(testRecord.getCreateTime()).orElse("--"));map.put("remark", Optional.ofNullable(testRecord.getRemark()).orElse("--"));//list所属系统//拼接数据结构// 2.商品详情列表填充List<Map<String, Object>> goodsWordList = new ArrayList<>();//下面的行数List<FillData> data = data(testRecord.getDetail(), vehiclePartsMap);for (int i = 0; i < data.size(); i++) {Map<String, Object> goodsMap = new HashMap<>();goodsMap.put("id", i + 1);goodsMap.put("item", Optional.ofNullable(data.get(i).getItem()).orElse("--"));goodsMap.put("result", Optional.ofNullable(data.get(i).getResult()).orElse("--"));goodsMap.put("partsName", Optional.ofNullable(data.get(i).getPartsName()).orElse("--"));goodsMap.put("subsystemName", Optional.ofNullable(data.get(i).getSubsystemName()).orElse("--"));goodsMap.put("trueOrFalse", Optional.ofNullable(data.get(i).getTrueOrFalse()).orElse("--"));goodsWordList.add(goodsMap);}map.put("goods", goodsWordList);arrayMap.add(map);}// 设置响应的内容类型response.setContentType("application/zip");response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");String zipName = URLEncoder.encode("F1检测信息报表.zip", "UTF-8").replaceAll("\\+", "%20");response.setHeader("Content-Disposition", "attachment;filename=" + zipName);try (ZipOutputStream zipOutputStream = new ZipOutputStream(response.getOutputStream())){for (Map<String, Object> data : arrayMap){//使用 ByteArrayOutputStream 来创建内存中的 Word 文件ByteArrayOutputStream wordOut = new ByteArrayOutputStream();//数据写入模板XWPFDocument document = new MyXWPFDocument(Objects.requireNonNull(this.getClass().getResourceAsStream("/template/testAF1.docx")));// 读取模板WordExportUtil.exportWord07(document, data);document.write(wordOut);// 添加Word文件到Zip包中zipOutputStream.putNextEntry(new ZipEntry(data.get("fileName") + ".docx"));zipOutputStream.write(wordOut.toByteArray());zipOutputStream.closeEntry();}zipOutputStream.finish();}catch (IOException e){e.printStackTrace();throw new RuntimeException("Error creating ZIP file",e);}return Result.success();}
