使用poi根據模版生成word文檔，支持插入數據和圖片

1、製做word模版，${xxxx}是一會要替換的內容，最下面的表格是要插入數據，根據是否以$開頭來判斷是須要替換仍是插入數據，

　　注意若是是須要插入數據，製做的表格模版須要一行空行，也只能有一行空行，緣由能夠看我代碼的邏輯，表格中${header}

　　和${hearder2}是放入須要替換的圖片

 

2、添加poi所須要的jar包文件，我用的maven對jar包進行管理

 

<dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi</artifactId>
      <version>3.11</version>
</dependency>
<dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi-ooxml</artifactId>
      <version>3.11</version>
</dependency>

 

 

3、因爲poi自身bug,會出現圖片沒法顯示問題，這裏須要自定義一個類繼承XWPFDocument類，接下來使用的都是咱們本身建立的這個類來操做word對象，這個

　　類對XWPFDocument進行了繼承，因此不用擔憂會有什麼問題

package com.cccuu.project.myUtils;
