1.功能實現(xiàn)
使用poi對進行word文件進行解析處理,使用aspose進行pdf轉(zhuǎn)換
aspose下載路徑：https://pan.baidu.com/s/1vJWgYAAaHpnXmyKhZa4ljg 提取碼：jdwp
注：如果導入了easyExcel姥宝，則只需要導入一部分poi(關(guān)于doc文件的解析)隧出，防止版本不一致的問題
2.導入依賴

<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.17</version>

<!--如果導入了easyExcel的导绷，只需要導入下面這個-->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-scratchpad</artifactId>
<version>3.17</version>
</dependency>

3.獲取word文件薇宠，替換其中的特殊字符：${name}
處理docx文件必須表格和段落分開處理阱当，doc文件則不需要單獨處理
/**

*

* @param outputStream 文件輸出流
* @param map ${name}的key的數(shù)據(jù)

5.下載和預覽中的response設置
//預覽
response.setContentType("application/pdf;charset=UTF-8");
//inline設置是強制瀏覽器顯示茄茁，attachment設置時強制瀏覽器下載
response.setHeader("Content-Disposition", "inline; filename= file");
//下載
response.setContentType("application/octet-stream");
String fileName = fileEntity.getFileName();
response.setHeader("Content-Disposition", "attachment;fileName=" + URLEncoder.encode(fileName, "utf-8"));
response.flushBuffer();
6.問題
1.如果發(fā)現(xiàn)讀取word文件失敗鹰祸，可能是word文件后綴與原始后綴不一致，如：新建一個doc,修改為后綴docx,這是讀取不了的跟继。
2.部署在linux种冬，預覽出現(xiàn)亂碼或者空白，是因為缺少字體導致
3.建議優(yōu)先選擇doc格式文件还栓，因為docx文件替換出來的字體不能匹配碌廓。
