aspose-words去水印自用资源
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>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</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PDFByteArrayInputStream wordInputStream = new ByteArrayInputStream(wordOutputStream.toByteArray());// 获得授权MatchLicense.init();Document doc = new Document(wordInputStream);doc.save(getOutputPath(), SaveFormat.PDF);
