推荐答案
主要问题是那些 PdfOptions
和 PdfConverter
不是 的一部分apache poi
项目.它们由 opensagres
开发,第一个版本被错误地命名为 org.apache.poi.xwpf.converter.pdf.PdfOptions
和 org.apache.poi.xwpf.转换器.pdf.PdfConverter
.那些旧类自 2014 年以来没有更新,需要使用 apache poi
的 3.9
版本.
The main problem with this is that those PdfOptions
and PdfConverter
are not part of the apache poi
project. They are developed by opensagres
and first versions were badly named org.apache.poi.xwpf.converter.pdf.PdfOptions
and org.apache.poi.xwpf.converter.pdf.PdfConverter
. Those old classes were not updated since 2014 and needs version 3.9
of apache poi
to be used.
使用最新的 fr.opensagres.poi.xwpf.converter.pdf,它使用最新的稳定版本apache poi 3.17
.
Do using the much more current fr.opensagres.poi.xwpf.converter.pdf, which works using the latest stable release apache poi 3.17
.
然后做
import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.File;
//needed jars: fr.opensagres.poi.xwpf.converter.core-2.0.1.jar,
// fr.opensagres.poi.xwpf.converter.pdf-2.0.1.jar,
// fr.opensagres.xdocreport.itext.extension-2.0.1.jar,
// itext-2.1.7.jar
import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;
import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;
//needed jars: apache poi and it's dependencies
import org.apache.poi.xwpf.usermodel.XWPFDocument;
public class DOCXToPDFConverterSampleMin {
public static void main(String[] args) throws Exception {
String docPath = "./WordDocument.docx";
String pdfPath = "./WordDocument.pdf";
InputStream in = new FileInputStream(new File(docPath));
XWPFDocument document = new XWPFDocument(in);
PdfOptions options = PdfOptions.create();
OutputStream out = new FileOutputStream(new File(pdfPath));
PdfConverter.getInstance().convert(document, out, options);
document.close();
out.close();
}
}
2018 年 10 月:此代码使用 apache poi 3.17
工作.它无法使用 apache poi 4.0.0
工作,因为 apache poi
中的更改未在 fr.opensagres.poi.xwpf.converter中考虑在内代码>直到现在.
October 2018:
This code works using apache poi 3.17
. It cannot work using apache poi 4.0.0
due to changings in apache poi
which were not taken in account in fr.opensagres.poi.xwpf.converter
until now.
2019 年 2 月:我现在使用最新的 apache poi
版本 4.0.1
和 fr.opensagres.poi.xwpf.converter.core 和配偶.
February 2019:
Works for me now using the newest apache poi
version 4.0.1
and the newest version 2.0.2
of fr.opensagres.poi.xwpf.converter.core and consorts.
2021 年 6 月:使用 apache poi
版本 4.1.2
和最新版本 2.0.2
的 fr.opensagres.poi.xwpf.converter.core 和配偶.无法使用 apache poi
版本 5.0.0
因为 XDocReport
需要 ooxml-schemas
而 apache poi 5
不再支持.
June 2021:
Works using apache poi
version 4.1.2
and the newest version 2.0.2
of fr.opensagres.poi.xwpf.converter.core and consorts.
Cannot work using apache poi
version 5.0.0
because XDocReport
needs ooxml-schemas
which apache poi 5
does not support anymore.
