引言:

最近公司在做一個教育培訓(xùn)學(xué)習(xí)及在線考試的項目,本人主要從事網(wǎng)絡(luò)課程模塊,主要做課程分類,課程,課件的創(chuàng)建及在線學(xué)習(xí)和統(tǒng)計的功能,因為課件涉及到多種類型,像視頻,音頻,圖文,外部鏈接及文檔類型.其中就涉及到一個問題,就是文檔型課件課程在網(wǎng)頁上的展示和學(xué)習(xí)問題,因為要在線統(tǒng)計學(xué)習(xí)的課程,學(xué)習(xí)的人員,學(xué)習(xí)的時長,所以不能像傳統(tǒng)做法將文檔下載到本地學(xué)習(xí),那樣就不受系統(tǒng)控制了,所以最終的方案是,在上傳文檔型課件的時候,將其文件對應(yīng)的轉(zhuǎn)換成HTML文件,以便在網(wǎng)頁上能夠瀏覽學(xué)習(xí)

下邊主要針對word,pdf和txt文本文件進行轉(zhuǎn)換

一:Java實現(xiàn)將word轉(zhuǎn)換為html
