实现类
/** * 通过documents4j 实现word转pdf * * @param sourcePath 源文件地址 如 /root/example.doc * @param targetPath 目标文件地址 如 /root/example.pdf */ public static void documents4jWordToPdf(String sourcePath, String targetPath) { File inputWord = new File(sourcePath); File outputFile = new File(targetPath); 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) { LOGGER.error("[documents4J] word转pdf失败:{}"+ e.toString()); // log.error("[documents4J] word转pdf失败:{}", e.toString()); } }
