poi导出复杂模板excel和word

导出复杂木板使用这个老哥的东西很好用

很方便的完成了，插入图片也有，只需要把图片转换成字节流。代码如下

    //初始化工具
        ExcelTemplate excel = new ExcelTemplate(filePath + fileName);

        /*javaBean转map*/
        Map<String, Object> map = getSevenInfo(affairSevenKnowledge);

            // 第一个参数，需要操作的sheet的索引
            // 第二个参数，需要复制的区域的第一行索引（占位符所在的第一行）
            // 第三个参数，需要复制的区域的最后一行索引（占位符所在的最后一行）
            // 第四个参数，需要插入的位置的索引(占位符的下一行)
            // 第五个参数，填充行区域中${}的值
            // 第六个参数，是否需要删除原来的区域
            // 需要注意的是，行的索引一般要减一
        try {
            excel.fillVariable(0, (Map<String, String>) map.get("param"));
            int i = excel.addRowByExist(0,14,14,15, (LinkedHashMap<Integer, LinkedList<String>>) map.get("rows"),true);
            //家庭成员和主要社会关系下方多处来的列合并到一个单元格
            //没有关系就不需要合并了
            if (i>0){
//                excel.mergedRegion(0,16,16+i+1,1,1);
            }
//            excel.addRowByExist(0,14,14,15,rows,true);
        } catch (IOException e) {
            e.printStackTrace();
        }
        // 第一个参数，需要操作的sheet的索引
            // 第二个参数，替换sheet当中${<变量的值>}的值

        //下载
        try {
            // 清除buffer缓存
            response.reset();
            response.setContentType("application/octet-stream; charset=utf-8");
            //指定下载名字
            response.setHeader("Content-Disposition", "attachment; filename="+

            response.addHeader("Cache-Control", "no-cache");
            OutputStream fout = response.getOutputStream();
            excel.getWorkbook().write(fout);
            fout.close();

        } catch (IOException e) {
            e.printStackTrace();
        }

导出word模板使用的这个老哥的东西

https://blog.csdn.net/qq_27828675/article/details/88708983
导出word模板还是挺坑的，word是由xml组成的。再word里编辑好占位符后，转成xml文档会发现，占位符已经分开了。我使用数字做占位符，转换成xml后把数字转换成需要的占位符。但是，
转换完后，有些占位符还是无法替换，再次转成xml发现，占位符还是分开了。。。。最后
我看了下老哥写的代码，我给改动了下，模板未匹配到的区域我给替换成了空字符串。修改后的代码如下

使用起来也是很方便的，代码如下

response.reset();
        response.setContentType("application/octet-stream; charset=utf-8");
        //指定下载名字
        response.setHeader("Content-Disposition", "attachment; filename="+
                Encodes.urlEncode("文件名.zip"));
        response.addHeader("Pargam", "no-cache");
        response.addHeader("Cache-Control", "no-cache");

        String fileSeperator = File.separator;
        String filePath = Global.getUserfilesBaseDir() + fileSeperator + "userfiles" + fileSeperator + "template" + fileSeperator;

        ZipOutputStream out = null;
        try {
            out = new ZipOutputStream(response.getOutputStream());
        } catch (IOException e) {
            e.printStackTrace();
        }
        ZipOutputStream finalOut = out;
        try {
            /*遍历所有人，每个对象准换为map*/
            for (PersonnelBase item : page.getList()) {
                Map<String, Object> map = getPersonnelBaseInfo(item, request);

                /*写入xlsx*/
                Map<String,Object> photo = (Map<String, Object>) map.get("excelPhoto");
                byte[] imageBytes = (byte[]) photo.get("imageBytes");

                excel.fillVariable(1, (Map<String, String>) map.get("sheet2"));
                int line = excel.addRowByExist(1, 5, 5, 6, (LinkedHashMap<Integer, LinkedList<String>>) map.get("rows"), true);
                if (photo.get("imageType") != null && imageBytes != null) {
                    int imageType = (int) photo.get("imageType");

                ZipEntry xlsx = new ZipEntry(item.getName() + "文件名.xlsx");
                finalOut.putNextEntry(xlsx);
                excel.getWorkbook().write(finalOut);

                /*写入doc*/
                ZipEntry docx = new ZipEntry(item.getName() + "文件名.docx");
                finalOut.putNextEntry(docx);
                String fileNameInResource = filePath + "文件名.docx";
                CustomXWPFDocument document = WordTemplate.changWord(fileNameInResource, personnelBase.getName() + "干部任免审批表.docx", (Map<String, Object>) map.get("doc"), null);
                document.write(finalOut);


            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                /*注意顺序 否则导致文件错误*/
                finalOut.flush();
                finalOut.close();
                response.getOutputStream().close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

就这么记记吧，突然想起来的，记的不是很详细了。
