word文檔處理成富文本生成sql語句導入mysql
問題：須要將大量的已存在的word文檔導入到web項目裏在網站展現，不可能經過編輯錄入的方式處理，經過程序實現。
解決思路：經過讀取word文檔處理成html，再獲取html富文本內容，拼接成sql，導入數據庫。html
要點
1：讀取word文件夾會遞歸讀取，只要文件夾下有word文檔便可，程序中有過濾word文檔的代碼，可根據須要修改；
二、可同時處理word2003和word2007+版本的word文檔；
三、讀取word2007生成的html文檔內中文是unicode編碼的，放到數據庫或瀏覽器直接打開，不影響頁面顯示；
四、對word文檔中圖片作了處理，存儲到單獨的文件夾，導入mysql或其它數據庫後，正確顯示圖片，要注意路徑處理；
五、只處理word2007文檔可不生成html直接獲取富文本內容，但2003版本不能夠，所以統一將doc文檔都生成html頁面再用java讀取html文檔獲取body元素下的富文本內容。java
不足之處，歡迎交流和指正。mysql
可能用到的pom以下：web
<!--poi處理word文檔--> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.15</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-scratchpad</artifactId> <version>3.15</version> </dependency> <dependency> <groupId>fr.opensagres.xdocreport</groupId> <artifactId>fr.opensagres.xdocreport.document</artifactId> <version>2.0.1</version> </dependency> <dependency> <groupId>fr.opensagres.xdocreport</groupId> <artifactId>org.apache.poi.xwpf.converter.xhtml</artifactId> <version>1.0.6</version> </dependency> <dependency> <groupId>fr.opensagres.xdocreport</groupId> <artifactId>org.apache.poi.xwpf.converter.core</artifactId> <version>1.0.6</version> </dependency> <dependency> <groupId>fr.opensagres.xdocreport</groupId> <artifactId>org.apache.poi.xwpf.converter.pdf</artifactId> <version>1.0.6</version> </dependency>
