word文档转pdf

1、导入所需依赖 aspose-words-15.8.0-jdk16.jar 下载

 		<dependency>
            <groupId>com.aspose</groupId>
            <artifactId>com-aspose</artifactId>
            <version>15.8.0</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/lib/aspose-words-15.8.0-jdk16.jar</systemPath>
        </dependency>

2、编写 license.xml license.xml授权码下载

备注：将license.xml放到resources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>
    授权码
  </Signature>
</License>

3、所需加载license.xml方法

/**
 * <p>
 * 服务初始化之后，执行方法
 * </p>
 *
 * @author AJIE
 * @description
 * @date 2022/03/02 
 */
@Slf4j
@Component
public class StartAppRunner implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        log.info("《服务初始化执行处理》 start...");
        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());
        }
        log.info("《服务初始化执行处理》 end...");
    }

}

4、word转pdf工具类

/**

@Slf4j
public class Word2PdfUtil {

    /**

     * @return 生成的`pdf`字节码

     */
    @SneakyThrows(Exception.class)
    public static byte[] wordBytes2PdfBytes(byte[] wordBytes) {
        Document document = new Document(new ByteArrayInputStream(wordBytes));
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        document.save(outputStream, SaveFormat.PDF);
        // 返回生成的`pdf`字节码
        return outputStream.toByteArray();
    }

    /**
     * `word` 转 `pdf`
     *
     * @param wordBytes:   word字节码
     * @param pdfFilePath: 需转换的`pdf`文件路径
     * @return 生成的`pdf`文件数据
