import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;public static void main(String[] args) {File inputWord = new File("E:\\111\\123.docx");File outputFile = new File("E:\\111\\123.pdf");try  {InputStream docxInputStream = new FileInputStream(inputWord);OutputStream outputStream = new FileOutputStream(outputFile);IConverter converter = LocalConverter.builder().build();converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();outputStream.close();} catch (Exception e) {e.printStackTrace();}}

/*** documents4j方式excel转pdf* @param file 源文件* @return 返回转成功的文件*/public static File wordToPDFByDocuments4j(File file) {File outputFile = new File(String.format("%s%s%s%s", file.getParentFile(),  File.separator, System.currentTimeMillis(), ".pdf"));try  {InputStream docxInputStream = new FileInputStream(file);OutputStream outputStream = new FileOutputStream(outputFile);IConverter converter = LocalConverter.builder().build();converter.convert(docxInputStream).as(DocumentType.XLSX).to(outputStream).as(DocumentType.PDF).execute();outputStream.close();} catch (Exception e) {e.printStackTrace();}return outputFile;}
