java中word、excel、ppt转PDF文件

1、pom.xm引入依赖

  <dependency>
      <groupId> com.aspose</groupId>
      <artifactId>aspose-cells</artifactId>
      <version>8.5.2</version>
    </dependency>

    <dependency>
      <groupId>com.aspose</groupId>
      <artifactId>aspose-slides</artifactId>
      <version>15.9.0</version>
    </dependency>

    <dependency>
      <groupId>com.aspose</groupId>
      <artifactId>aspose-words</artifactId>
      <version>15.8.0</version>
    </dependency>

2、转换工具类

import cn.hutool.core.util.IdUtil;

3、license文件(放在项目classpath资源目录 license.xml)
