Java实现word转pdf并在关键字位置插入图片
作者：小七蒙恩
这篇文章主要为大家详细介绍了如何利用Java实现word转pdf,并在word中关键字位置插入图片,感兴趣的小伙伴可以跟随小编一起学习一下
java word转pdf、word中关键字位置插入图片 工具类
1.pom依赖
<dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.15</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.15</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-scratchpad</artifactId> <version>3.15</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>ooxml-schemas</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml-schemas</artifactId> <version>3.15</version>
2.依赖jar包
<dependency>
<groupId>com.aspose</groupId>
<artifactId>aspose-words</artifactId>
<version>15.8.0</version>
<scope>system</scope>
<systemPath>${pom.basedir}/src/main/webapp/WEB-INF/lib/aspose-words-15.8.0-jdk16.jar</systemPath>
</dependency>
aspose-words是需要在我们项目中引入的，并且使用时要在resouces目录下导入license.xml文件，否则生成的文件抬头会有红色的license信息。
3.工具类
