java中的Docx到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，在我的项目中只有一些依赖使用
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()); } } 例外：

这个问题的主要问题是那些PdfOptions和PdfConverter不是apache poi项目的一部分。 它们由opensagres开发，第一个版本命名为org.apache.poi.xwpf.converter.pdf.PdfOptions和org.apache.poi.xwpf.converter.pdf.PdfConverter 。 这些旧类自2014年以来未更新，需要使用版本3.9的apache poi 。
使用更新的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 。 由于apache poi中的变化而在fr.opensagres.poi.xwpf.converter中没有考虑到它现在使用apache poi 4.0.0无法工作。
