1、直接在Java程式碼裡建立Word檔案,設定格式樣式等,然後匯出。(略)
2、富文字轉換後的HTML下載為Word檔案。相當於把HTML轉為Word匯出
3、使用模板技術匯出。固定格式、可以寫入不同資料
其他:
.doc application/msword
.dot application/msword
.docx application/vnd.openxmlformats-officedocument.wordprocessingml.document
.dotx application/vnd.openxmlformats-officedocument.wordprocessingml.template

//BufferedOutputStream緩衝流:可以將資料快取在記憶體中,以減少對底層IO的呼叫次數,從而提高效能。
//ServletOutputStream:用於向用戶端傳送資料的
//因為需要將資料寫入HTTP響應,所以使用ServletOutputStream是更好的選擇。

out.write(outputStream.toByteArray());

使用Thymeleaf模板技術(推薦,也是我使用的)。也可以使用FreeMarker
Word檔案的格式是固定
可以根據需求寫入不同的資料
