在最近的一個(gè)項(xiàng)目中需要將一段字符類型的文本存為word，html并要將word的內(nèi)容保存在數(shù)據(jù)庫(kù)中，于是就有了如下的一個(gè)工具類，希望能對(duì)碰到這樣需求的朋友提供點(diǎn)幫助。
匆匆忙忙的就copy上來(lái)了，沒(méi)有做一些刪減，有一些多余的東西，有興趣的朋友可以自行略去。我的注釋相對(duì)比較清楚，可以按照自己的需求進(jìn)行組合。
在操作word的地方使用了jacob(jacob_1.9)，這個(gè)工具網(wǎng)上很容易找到，將jacob.dll放置系統(tǒng)Path中，直接放在system32下也可以，jacob.jar放置在classPath中。
代碼如下：WordBridge.java
