以下代码不适用于 Apache poi 3.16。 有人可以提供正确的解决方案吗,在我的项目中有一些只使用
public void ConvertToPDF(String docPath, String pdfPath) {
try {
InputStream doc = new FileInputStream(new File(docPath));
XWPFDocument document = new XWPFDocument(doc);
PdfOptions options = PdfOptions.create();
OutputStream out = new FileOutputStream(new File(pdfPath));
PdfConverter.getInstance().convert(document, out, options);
System.out.println("Done");
} catch (FileNotFoundException ex) {
System.out.println(ex.getMessage());
} catch (IOException ex) {
System.out.println(ex.getMessage());
}
}
异常(exception):

最佳答案
这样做的主要问题是那些 PdfOptions
和 PdfConverter
不属于 apache poi
项目。它们由 opensagres
开发并且第一个版本的命名很糟糕 org.apache.poi.xwpf.converter.pdf.PdfOptions
和 org.apache.poi.xwpf.converter.pdf.PdfConverter
.这些旧类(class)自 2014 年以来未更新,需要版本 3.9
的 apache poi
被使用。
请使用更当前的 fr.opensagres.poi.xwpf.converter.pdf ,它使用最新的稳定版本 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.它不能使用 apache poi 4.0.0
工作由于 apache poi
的变化fr.opensagres.poi.xwpf.converter
中没有考虑到这些直到现在。
2019 年 2 月:
现在使用最新的 apache poi
为我工作版本 4.0.1
和最新版本 2.0.2
的 fr.opensagres.poi.xwpf.converter.pdf和配偶。
2021 年 6 月:
使用 apache poi
工作版本 4.1.2
和最新版本 2.0.2
的 fr.opensagres.poi.xwpf.converter.pdf和配偶。
无法使用 apache poi
工作版本 5.0.0
因为XDocReport
需求ooxml-schemas
哪个apache poi 5
不再支持。
2022 年 4 月:
使用 apache poi
工作版本 5.2.2
和最新版本 2.0.3
的 fr.opensagres.poi.xwpf.converter.pdf和配偶。
