代码Demo：

    public static void main(String[] args) {
        HashMap<String, Object> dataMap = new HashMap<>();
        Map<String, Object> data = new HashMap<String, Object>();
        ArrayList<Map<String, Object>> dataList = new ArrayList<>();
        //封装数据
        data.put("username", "demo");
        data.put("password", "001");
        data.put("head", Pictures.ofLocal("C:\Users\Pictures\Saved Pictures\ais.jpg")
                .size(35, 35).create());
        dataList.add(data);
        //key要和模板中的开始结束标签保持一致
        dataMap.put("wordExportTemp", dataList);
        try {
            String res = wordUtil.tempRender(dataMap);
            System.out.println(res);
        } catch (Exception e) {
            System.out.println("Fail");
        }
    }

public class wordUtil {
    public static String tempRender(HashMap<String, Object> dataMap) throws Exception {
        //模板文件
        String inPut = "D:\tempword\data\wordFile.docx";
        //生成文件
        String outPut = "D:\tempword\data\2021-09-15\exportWord.docx";
        //获取模板文件数据
        XWPFWordExtractor extractor = new XWPFWordExtractor(OPCPackage.open(new FileInputStream(inPut)));
        //获取String型模板数据
        System.out.println(extractor.getText());
        FileOutputStream outputStream = new FileOutputStream(outPut);
        //用来
        ConfigureBuilder builder = Configure.builder();
        //用默认的方式抛出异常
        builder.useDefaultEL(true);
        //匹配除了标签前后缀外的任意字符
        builder.buildGrammerRegex(RegexUtils.createGeneral("{{", "}}"));
        //创建结果对象
        XWPFTemplate docx = XWPFTemplate.compile(inPut,builder.build());
        //数据渲染
        docx.render(dataMap);
        //数据写出
        docx.write(outputStream);
        outputStream.flush();
        outputStream.close();
        docx.close();
        return "OK";
    }
}

模板：

注意：{{?wordExportTemp}} 中的“wordExportTemp”要和封装数据Map的“key"保持一致！
