java中word快速轉pdf

網上其他方法轉pdf要不轉的太慢，要不就是損失格式，故而留下此方法留作備用。

一、依賴

<dependency><groupId>com.aspose</groupId><artifactId>aspose-words</artifactId><version>21.6</version><classifier>jdk16</classifier>
</dependency>

二、依賴包

請將aspose.7z文件解壓，將解壓后文件放到maven的com目錄下。

三、代碼

package com.tdxx.common.utils;import com.aspose.words.Document;
