引入依赖 (maven仓库是没有的，需要在项目中引用)

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

resource下添加license.xml文件 

<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>

核心代码 

import com.aspose.words.Document;
import com.aspose.words.SaveFormat;
import lombok.SneakyThrows;
import org.springframework.core.io.ClassPathResource;import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;public class Doc2Pdf {@SneakyThrowspublic static void main(String[] args) {doc2pdf("D:\\土建小程序用图\\测试doc转pdf\\平面图测试.doc","D:\\土建小程序用图\\测试doc转pdf\\我的测试.pdf");//第一个参数是要转换的文件，第二个参数是转换后所得的文件//注意第二参数的文件类型要与下面代码 doc.save(os, SaveFormat.PDF) 的类型保持一致}private static boolean license = false;public static String doc2pdf(String inPath, String outPath) throws Exception {FileOutputStream os = null;try {//凭证 不然切换后有水印InputStream is = new ClassPathResource("/ceFile/license.xml").getInputStream();com.aspose.words.License aposeLic = new com.aspose.words.License();aposeLic.setLicense(is);license = true;if (!license) {System.out.println("License验证不通过...");return null;}//生成一个空的PDF文件File file = new File(outPath);os = new FileOutputStream(file);//要转换的word文件Document doc = new Document(inPath);doc.save(os, SaveFormat.PDF);} catch (Exception e) {e.printStackTrace();} finally {if (os != null) {try {os.close();} catch (IOException e) {e.printStackTrace();}}}return null;}
}

效果如下（无水印）：
