Java實現Word轉PDF方案選擇
很多應用場景中都會涉及到Word轉PDF，但Word轉PDF的方案在網上一搜一大把，讓人眼花繚亂，筆者踩過無數的坑後，最終總結出以下三種方案
- OpenOffice實現Word轉ODF
- docx2pdf實現Word轉ODF
- itext+POI實現Word轉ODF
方案
- OpenOffice實現Word轉ODF
- 這種方案在Windows中可行，且非常簡便，但它完全依賴於OpenOffice，想在Linux中實現，顯然不是一個好的方案，筆者嘗試過Linux中裝OpenOffice，但令人髮指的是居然還需要裝GUI！
Java程式碼

import java.net.ConnectException;
import com.artofsolving.jodconverter.DocumentConverter;
import com.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection;
import com.artofsolving.jodconverter.openoffice.connection.SocketOpenOfficeConnection; - docx2pdf實現Word轉ODF
- 這種方案在Windows和Linux中都可用，但有一點需要注意，它只支援07以上的Word轉換，很不幸，筆者的Word模版是03的，只能用第三種方案了。事實上，這種方案中也依賴了Itext的包

- itext+POI實現Word轉ODF
- 這種方案也就是先解析Word，然後將內容轉換到PDF中，是三種方案中最繁瑣的選擇，但如果你的Word模板不是07以上的，而線上環境是Linux，這是最後的選擇了
