由于項目中之前就有，是以直接照搬。word轉pdf，使用的是ASPOSE.word ，ASPOSE.word的licence需要收費
package com.biolims.report.service;
import java.io.FileOutputStream;
import java.io.InputStream;
import com.aspose.words.Document;
import com.aspose.words.License;
import com.aspose.words.SaveFormat;
/**
*
* 由于ASPOSE比較吃記憶體，操作大一點的檔案就會堆溢出，是以請先設定好java虛拟機參數：-Xms512m -Xmx512m(參考值)<br>
* 如有疑問，請在CSDN下載下傳界面留言,或者聯系QQ569925980<br>

} pdf轉圖檔，再插入pdf，使PDF就算用專業軟體也不能打開，但是我們上司覺得可能多頁會出現問題，但是還沒有好的解決辦法，如果有了請評論告知，不勝感激
