程式碼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<>();
        //封裝資料
        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要和模板中的開始結束標籤保持一致
        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 {
        
 
//模板檔案
        String inPut = "D:\\tempword\\data\\wordFile.docx";
        //生成檔案
        String outPut = "D:\\tempword\\data\\2021-09-15\\exportWord.docx";
        //獲取模板檔案資料
        XWPFWordExtractor extractor = new XWPFWordExtractor(OPCPackage.open(new FileInputStream(inPut)));
        //獲取String型模板資料
        System.out.println(extractor.getText());
        FileOutputStream outputStream = new FileOutputStream(outPut);
        //用來
        ConfigureBuilder builder = Configure.builder();
        //用預設的方式丟擲異常
        builder.useDefaultEL(true);
        //匹配除了標籤前後綴外的任意字元
        builder.buildGrammerRegex(RegexUtils.createGeneral("{{", "}}"));
        //建立結果物件
        XWPFTemplate docx = XWPFTemplate.compile(inPut,builder.build());
        //資料渲染
        docx.render(dataMap);
        //資料寫出
        docx.write(outputStream);
        outputStream.flush();
        outputStream.close();
        docx.close();
        return "OK";
    }
}

模板：

注意：{{?wordExportTemp}} 中的“wordExportTemp”要和封裝資料Map的“key"保持一致！

結果
