工具类

@Slf4j
public class DocTransferUtil {
	//当类被加时就自动执行下方代码块
    static {
        //去掉转成PDF后的文件上方有Aspose的对应的版权信息，需要使用授权下方的license。
        try {
            // 设置word license
            ClassPathResource classPathResource = new ClassPathResource("license/license-word.xml");
            InputStream is = classPathResource.getInputStream();
            License aposeLic = new License();
            aposeLic.setLicense(is);

            // 设置pdf license
            ClassPathResource classPathResource2 = new ClassPathResource("license/license-pdf.xml");
            InputStream licensePdf = classPathResource2.getInputStream();
            com.aspose.pdf.License aposeLicPdf = new com.aspose.pdf.License();
            aposeLicPdf.setLicense(licensePdf);
            is.close();
            licensePdf.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

测试

@GetMapping("/testword2pdf")
publicvoid testword2pdf() throws Exception {
    byte[] src = cn.hutool.core.io.FileUtil.readBytes("C:\\Users\\Administrator\\Desktop\\测试文件.docx");//原始的word文件
    long old = System.currentTimeMillis();
    byte[] target = DocTransferUtil.word2pdf(src);
    long now = System.currentTimeMillis();
    //转化用时
    log.info("word2pdf 耗时 {} 秒", ((now - old) / 1000.0));
    cn.hutool.core.io.FileUtil.writeBytes(target, "C:\\Users\\Administrator\\Desktop\\123432.pdf");//生成的pdf文件
}
