使用poi-tl导出图文交替的word文档

用poi-tl生成word文档还是很方便的,代码如下

Map<String, List<Map<String, Object>>> datasMap = new HashMap<>();
        List<Map<String, Object>> list1 = new ArrayList<>();
        XWPFTemplate template = null;
        FileOutputStream out = null;
        String picDirRoot = appConfig.getPicDirRoot();
        try {
            for (Analysis analysis : list) {
                String tags = analysis.getTag();
                String imgPath1 = analysis.getImgPath();
                String imgName = analysis.getImgName();
                String selected = analysis.getSelected();
                String imgPath = picDirRoot + imgPath1 + File.separator + imgName;
                if (StringUtils.isBlank(tags)) {
                    copyPictures(resultTagsSet, selectedTagsSet, imgName, selected, imgPath, "default",subRecordId);
                } else {
                    String[] split = tags.split(";");
                    // 图片按标签分类保存
                    for (String tag : split) {
                        copyPictures(resultTagsSet, selectedTagsSet, imgName, selected, imgPath, tag,subRecordId);
                    }
                }
                if ("true".equals(selected)) {
                    // 生成word文档
                    Map<String, Object> datas = new HashMap<>();
                    BufferedImage bufferedImage = ImageIO.read(new File(imgPath));
                    int width = bufferedImage.getWidth();
                    int height = bufferedImage.getHeight();
                    int newheight = height * 500 / width;
                    datas.put("tag", analysis.getTag());
                    datas.put("picture", new PictureRenderData(500, newheight, imgPath));
                    list1.add(datas);
                }
            }
            datasMap.put("item", list1);
            String reportDir = appConfig.getReportDir();
            XWPFTemplate compile = XWPFTemplate.compile(reportDir + AppConstants.MODULE_NAME);
            template = compile.render(datasMap);
            String uuid = StrUtils.uuid();
            out = new FileOutputStream(reportDir + uuid + ".docx");
            template.write(out);
            out.flush();
            out.close();
            template.close();
            // 下载报告
            File file = new File(reportDir + uuid + ".docx");
            downloadFile(file, response, request);
            file.delete();
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
            result.setCode("1");
            result.setMessage("报告生成失败");
        }finally {
            if (out != null) {
                try {
                    out.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            if (template != null) {
                try {
                    template.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }

这里生成的word文档是图文交替的,这里使用到poi-tl的区块对,详细内容请查看文档,template.docx内容如下:

{{?item}}

{{tag}}

{{@picture}}

{{/item}}

生成的结果如图:
