官方文档https://docs.aspose.com/words/java/convert-a-document-to-pdf/

声明：限个人学习使用，商用后果与本人无关。

1.引入依赖

    <dependencies>
        <dependency>
            <groupId>com.aspose</groupId>
            <artifactId>aspose-words</artifactId>
            <version>18.6</version>
            <classifier>jdk16</classifier>
        </dependency>
    </dependencies>
    <repositories>
        <repository>
            <id>aspose-maven-repository</id>
            <url>https://artifact.aspose.com/repo/</url>
        </repository>
    </repositories>

2.下载依赖后去依赖仓库位置删掉从官方源下载的版本

仓库路径/com/aspose/aspose-words/18.6

删除路径中aspose-words-18.6-jdk16.jar文件，使用我的资源文件替换

3.添加license.xml文件到src/main/resources目录下

<License>
  <Data>
    <Products>
      <Product>Aspose.Total for Java</Product>
      <Product>Aspose.Words for Java</Product>
    </Products>
    <EditionType>Enterprise</EditionType>
    <SubscriptionExpiry>20991231</SubscriptionExpiry>
    <LicenseExpiry>20991231</LicenseExpiry>
    <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>
  </Data>

  </Signature>
</License>

4.添加工具类代码

@Slf4j
public class MatchLicense {

    public static void init() {
        try {
            log.info("实现aspose-words授权 -> 去掉头部水印");
            /*
              实现匹配文件授权 -> 去掉头部水印 `Evaluation Only. Created with Aspose.Words. Copyright 2003-2018 Aspose Pty Ltd.` |
                                          `Evaluation Only. Created with Aspose.Cells for Java. Copyright 2003 - 2020 Aspose Pty Ltd.`
             */
            InputStream is = new ClassPathResource("license.xml").getInputStream();
            License license = new License();
            license.setLicense(is);
        } catch (Exception e) {
            log.error("《aspose-words授权》 失败： {}", e.getMessage());
        }
    }
}

5.使用示例：在使用api前调用方法即可

        // 将Word文档转换为PDF
        ByteArrayInputStream wordInputStream = new ByteArrayInputStream(wordOutputStream.toByteArray());
        // 获得授权
        MatchLicense.init();
        Document doc = new Document(wordInputStream);
        doc.save(getOutputPath(), SaveFormat.PDF);
