Java中的Docx至Pdf转换器

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,有些人只能使用

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());

}

}

Exception:

回答:

这个主要的问题是,那些PdfOptionsPdfConverter是不是的一部分apache poi项目。它们是由开发的opensagres

第一个版本的命名错误org.apache.poi.xwpf.converter.pdf.PdfOptionsorg.apache.poi.xwpf.converter.pdf.PdfConverter。这些老班都没有更新,因为2014年和需要的版本3.9中apache poi使用。

请使用更多 最新版本的

fr.opensagres.poi.xwpf.converter.pdf,该版本可以使用最新的稳定版本进行工作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:此代码可使用apache poi 3.17。使用它不能工作,apache poi 4.0.0由于changings apache poi这不采取

帐户fr.opensagres.poi.xwpf.converter直到现在。


2019年2月:对我的作品现在使用的最新apache poi版本4.0.1和最新版本2.0.2的

fr.opensagres.poi.xwpf.converter.core和配偶。
