java實現(xiàn)word文件轉(zhuǎn)html文件

更新時間：2017年03月23日 15:59:54 作者：littleFatty

這篇文章主要為大家詳細(xì)介紹了java實現(xiàn)word文件轉(zhuǎn)html文件的方法，具有一定的參考價值，感興趣的小伙伴們可以參考一下

最近在項目開發(fā)中用戶提出要在電腦上沒有裝office時在瀏覽器中打開word文件，最后確定的邏輯：用戶選擇想要查看的文件，頁面js判斷文件是否為word。不是執(zhí)行下載，是后端根據(jù)word文件后綴訪問對應(yīng)轉(zhuǎn)換方法。文件已存在對應(yīng)html文件直接返回html文件地址，不存在先生成對應(yīng)html文件再返回地址。js直接通過open()打開新的頁簽，展示word文件內(nèi)容。新人一枚，如果代碼中存在錯誤或有更好的實現(xiàn)萬望指正！
