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。

aspose-words-15.8.0-jdk16.jar 与license.xml
