java将word转pdf

poi工具转换

        <!-- 处理PDF --><dependency><groupId>fr.opensagres.xdocreport</groupId><artifactId>fr.opensagres.poi.xwpf.converter.pdf-gae</artifactId><version>2.0.3</version></dependency>

这个工具使用了poi,最新的2.0.3对应poi的5.2.0,2.0.1对应poi的3.15

使用

//拿到word流
InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("word/muban3.docx");if (inputStream == null) {throw new MsgException("读取模板失败");}
XWPFDocument document = new XWPFDocument(inputStream);
//.....word处理
PdfOptions pdfOptions = PdfOptions.create();//.fontEncoding( BaseFont.CP1250 );
//转pdf操作 (直接写入响应)
PdfConverter.getInstance().convert(document, response.getOutputStream(), pdfOptions);
response.setContentType("application/pdf");

或者写入输出流

    /*** 将word转为pdf并返回一个输出流** @param document 输出文件名(pdf格式)*/public static ByteArrayOutputStream wordToPdfOutputStream(XWPFDocument document) throws IOException {//word转pdfByteArrayOutputStream outputStream = new ByteArrayOutputStream();PdfOptions pdfOptions = PdfOptions.create();//.fontEncoding( BaseFont.CP1250 );//转pdf操作PdfConverter.getInstance().convert(document, outputStream, pdfOptions);return outputStream;}

问题

poi改了word之后，生成没问题,word中创建的表格，转pdf的时候经常出问题（直接报错或者合并无效）
在这里插入图片描述

研究了2天,pdf转一直各种问题,一起之下换技术

aspose-words

        <dependency><groupId>com.luhuiguo</groupId><artifactId>aspose-words</artifactId><version>23.1</version></dependency>

poi处理word一堆的依赖,这个一个就好,而且本身就支持转pdf!!!

使用

在resources创建word-license.xml

}

使用

Doc2PdfUtil.word2Pdf("aa.docx","bb.pdf");

我是依旧使用poi处理word,用这个转pdf

//拿到word流
InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("word/muban3.docx");if (inputStream == null) {throw new MsgException("读取模板失败");}
XWPFDocument document = new XWPFDocument(inputStream);
//.....word处理ByteArrayInputStream in = null;try {//由于使用的poi的document,需要现将poi的document转为普通的输入流in = WordUtil.getInputStream(document);Doc2PdfUtil.word2Pdf(in,response.getOutputStream());response.setContentType("application/pdf");} catch (Exception e) {log.error("报告下载失败", e);} finally {try {document.close();} catch (Exception e1) {log.error("document 流关闭失败", e1);}if (in != null) {try {in.close();} catch (Exception e1) {log.error("in 流关闭失败", e1);}}}

    public static ByteArrayInputStream getInputStream(XWPFDocument document) {ByteArrayOutputStream outputStream = new ByteArrayOutputStream();try {document.write(outputStream);return outputStreamToPdfInputStream(outputStream);} catch (IOException e) {throw new RuntimeException(e);} finally {if (outputStream != null) {try {outputStream.close();} catch (IOException e) {throw new RuntimeException(e);}}}}/*** 将word转为pdf并返回一个输入流** @param outputStream 输出文件名(pdf格式)*/public static ByteArrayInputStream outputStreamToPdfInputStream(ByteArrayOutputStream outputStream) throws IOException {//输出的pdf输出流转输入流try {//临时byte[] bookByteAry = outputStream.toByteArray();return new ByteArrayInputStream(bookByteAry);} catch (Exception e) {e.printStackTrace();return null;}}
