JAVA生成Word文档

第一步：导入依赖

<!--生成word文档-->
<dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.10.3</version>
</dependency>
<!--数字转为汉字大写-->
<dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId>
</dependency>

第二步：业务代码 

  @Overridepublic void downloadEngineeringWord(HttpServletResponse response, Long engineeringId) {String engineeringWordSql = "你的查询sql";Map<String, Object> tendersWord = (Map<String, Object>) SqlUtil.getMapToList(engineeringWordSql, entityManager).get(0);if (ObjectUtils.isEmpty(tendersWord)) {return;}//判断文本是否出现if (tendersWord.containsKey("margin") && !ObjectUtils.isEmpty(tendersWord.get("margin"))) {BigDecimal price = (BigDecimal) tendersWord.get("margin");tendersWord.put("marginShow", price.signum() > 0);} else {tendersWord.put("marginShow", false);}//将数字金额转为汉字大写if (tendersWord.containsKey("maxPrice") && !ObjectUtils.isEmpty(tendersWord.get("maxPrice"))) {double money = Double.parseDouble(tendersWord.get("maxPrice").toString());String chineseMoney = NumberChineseFormatter.format(money, true, true);tendersWord.put("highestPrice", chineseMoney);}//对前端使用\n换行的段落文本进行格式化换行Object qualifications = tendersWord.get("qualifications");if (!ObjectUtils.isEmpty(qualifications) && qualifications.toString().contains("/")) {List<String> qualificationsList = Arrays.asList(qualifications.toString().split("/"));List<Map<String, Object>> qualificationMapList = new ArrayList<>();qualificationsList.stream().filter(f -> !ObjectUtils.isEmpty(f.trim())).forEach(qualification -> {Map<String, Object> itemMap = new HashMap<>();itemMap.put("qualification", qualification);qualificationMapList.add(itemMap);});tendersWord.put("qualifications", qualificationMapList);}String fileName = "工程文件";try {File wordTemplate = new File("start/src/main/resources/" + fileName + ".docx");XWPFTemplate template = XWPFTemplate.compile(wordTemplate.getAbsolutePath()).render(tendersWord);response.setCharacterEncoding("UTF-8");response.setContentType("multipart/form-data");response.addHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName + ".docx", "utf-8"));response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");OutputStream out = response.getOutputStream();BufferedOutputStream bos = new BufferedOutputStream(out);template.write(bos);bos.flush();out.flush();PoitlIOUtils.closeQuietlyMulti(template, bos, out);} catch (IOException e) {throw new BizException(fileName + ".docx 生成失败，请稍后再试！");}}
