图片处理

details是要遍历的表格里得数据，图片支持多张

        List<InfViolationDetail> details = infViolationDetailService.selectList(search);
 
 
        // 输出的图片对象列表
        List<PictureRenderData> imgList = null;
        if (!CollectionUtils.isEmpty(details)) {
            for (int i = 1; i <= details.size(); i++) {
                details.get(i-1).setId(Long.valueOf(i));
                String violationImg = details.get(i-1).getViolationImg();
                // 输出的图片对象列表
                imgList = new ArrayList<>();
                if (StringUtil.isNotBlank(violationImg)) {
                    violationImg = ","+violationImg;
                    String []urlStrs = violationImg.split(",");
                    for (int j = 0; j < urlStrs.length; j++) {
                        String url = platformUrl+urlStrs[j];
                        PictureRenderData picItem = Pictures.ofUrl(url).size( 60, 50) .center().create();
                        imgList.add(picItem);
                    }
                }
                details.get(i-1).setImgList(imgList);
            }
        }

 获取模板，绑定模板里得内容

InputStream resourceAsStream = ResourceReader.class.getClassLoader().getResourceAsStream("导出模板.docx");
        Map<String, Object> datas = new HashMap<String, Object>() {
            {
                put("details", details);
 
                put("violationStartPosition",infViolation.getViolationStartPosition());
                put("violationTime",DateUtils.dateToc(infViolation.getViolationTime()));
                put("ext1",infViolation.getExt1());
                put("ext19",infViolation.getExt19());
                put("ext15",infViolation.getExt15());
                put("ext20",infViolation.getExt20());
                put("inspector",infViolation.getInspector());
                put("ext21",infViolation.getExt21());
                put("punishmentSituation",infViolation.getPunishmentSituation());
                put("ext27",infViolation.getExt27());
                put("ext28",infViolation.getExt28());
                put("sgEnterName",infViolation.getSgEnterName());
            }
        };
 
        LoopRowTableRenderPolicy policy = new LoopRowTableRenderPolicy();
        Configure config = Configure.builder()
                .bind("details", policy).build();
 
        XWPFTemplate template = XWPFTemplate.compile(resourceAsStream,config).render(datas);
        Map<String, Object> map = new HashMap<>();
        map.put("template", template);
        map.put("fileName", infViolation.getViolationStartPosition());
        return map;

输出word

    protected void buildWordDocument(String fileName, XWPFTemplate document, HttpServletResponse response) throws Exception {
 
        response.reset();
        response.setContentType("application/octet-stream");
        response.setHeader("Content-disposition", "attachment;filename="+ fileName + ";filename*=utf-8''" + URLEncoder.encode(fileName, "UTF-8"));
        OutputStream os = response.getOutputStream();
        document.write(os);
        os.close();
    }
