步驟

1.首先將你要生成的pdf，用worl畫出來，比如你需要特定結構的pdf，你沒辦法做到，但是一個wold你可以通過編輯，得到你想要的模板。如下：（你想要替換的內容換成${arg0!""},就是用將來你需要替換的數據暫時用變量表示出來，後續只要替換變量的值即可！而模板本身不變）

2.其次將word的字體換成宋體（通用），文件另存爲xml格式文件如下：

3.將文件改名，以.ftl形式結尾（利用freemarker，所以改成freemarker文件形式）

4.讀取ftl文件，將其轉化成xml字符串。讀取xml字符串，將其轉換成word，讀取word，利用dom4j將其轉換成你想要的模式的pdf
