总结
建议使用aspose-words转pdf,poi的容易出问题还丑…
poi的(多行的下边框就不对了)
aspose-words的(基本和word一样)
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pdf
ByteArrayOutputStream 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）
研究了2天,pdf转一直各种问题,一起之下换技术
aspose-words
https://blog.csdn.net/Wang_Pink/article/details/141898210
<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
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;
}
}
完美转换
