前言

該需求就是在pdf/word中，根據定義的關鍵字標識，進行插入圖片。不多說直接上代碼。
工具類都是參照網上的進行小改一番

PDF根據關鍵字插入圖片

1、引入依賴

<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.6</version> </dependency>

2、插入圖片工具類

import java.awt.*; import java.io.*; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map;import antlr.ANTLRError; import com.itextpdf.awt.geom.Rectangle2D;

注意：

1、PDF設置關鍵字時，轉Word設置再轉PDF是無法正確識別關鍵字，這邊建議比較好用的PDF編輯器:迅捷PDF編輯器。

2、pdfover和copyFileUsingStream方法自行選擇，用不到可以自行刪除。

3、代碼有的考慮的不是很全，各位大佬可以自行優化。

Word根據關鍵字插入圖片

Word插入我這有兩種，可自行選擇，都是從網上搜索然后小改

1、方式一

1.1、導入依賴

<!--注意:word中要使用循環等標簽必須單獨導入以下依賴--> <dependency><groupId>org.apache.poi</groupId><artifactId>ooxml-schemas</artifactId><version>1.4</version> </dependency> <!-- word導出 方式：easypoi--> <dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-base</artifactId><version>4.3.0</version> </dependency> <dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-web</artifactId><version>4.3.0</version> </dependency>
