java读取word文件转html

借助第三方jar包实现

pom.xml

<dependency>
	<groupId>com.aspose</groupId>
	<artifactId>aspose-words</artifactId>
	<version>15.12.0</version>
	<classifier>jdk16</classifier>
</dependency>

如果pom.xml无法成功下载，可以通过以下方法：

1. 下载jar包到本地。下载路径：https://releases.aspose.com/zh/words/java/
2. 添加jar包到项目下。添加路径：项目根目录下的lib文件夹
3. pom.xml中引用jar包

<dependency>
	<groupId>com.aspose.words</groupId>
	<artifactId>aspose-words</artifactId>
	<version>15.12.0</version>
	<scope>system</scope>
	<systemPath>${project.basedir}/lib/aspose-words-15.12.0-jdk16.jar</systemPath>
</dependency>
