Konwersja docx do pdf w java

Question

Próbuję przekonwertować plik docx, który zawiera tabelę i obrazy do pliku formatu pdf.

Szukałem wszędzie, ale nie mieli właściwego rozwiązania, zażądać, aby dać właściwe i prawidłowe rozwiązanie:

tutaj co próbowałem:

import java.io.File; 
import java.io.FileInputStream; 
import java.io.FileNotFoundException; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.OutputStream; 
import org.apache.poi.xwpf.converter.pdf.PdfConverter; 
import org.apache.poi.xwpf.converter.pdf.PdfOptions; 
import org.apache.poi.xwpf.usermodel.XWPFDocument; 

public class TestCon { 

    public static void main(String[] args) { 
     TestCon cwoWord = new TestCon(); 
     System.out.println("Start"); 
     cwoWord.ConvertToPDF("D:\\Test.docx", "D:\\Test1.pdf"); 
    } 

    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()); 
     } 
    } 

} 

Wyjątek:

Moim żądaniem jest utworzenie kodu Java do konwersji istniejącego dokumentu docx do formatu pdf z odpowiednim formatem i wyrównaniem.

Proszę sugerować. Słoiki Używane:

EDIT: Szukałem tego API, https://cloudconvert.com/api, ktoś wie jak zaimplementować to w kodzie Java.

Answer 1

Brakuje niektórych bibliotek.

jestem w stanie uruchomić kod poprzez dodanie następujących bibliotek:

 
    Apache POI 3.15 
    org.apache.poi.xwpf.converter.core-1.0.6.jar 
    org.apache.poi.xwpf.converter.pdf-1.0.6.jar 
    fr.opensagres.xdocreport.itext.extension-2.0.0.jar 
    itext-2.1.7.jar 
    ooxml-schemas-1.3.jar 

I zostały pomyślnie konwertowane dokument 6 stron Word (.docx) z tabel, obrazów i różnych formatowania.

Oprócz VivekRatanSinha answer, chciałbym zamieścić pełny kod i wymagane słoiki dla ludzi, którzy potrzebują go w przyszłości.

Kod:

import java.io.File; 
import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.OutputStream; 

import org.apache.poi.xwpf.converter.pdf.PdfConverter; 
import org.apache.poi.xwpf.converter.pdf.PdfOptions; 
import org.apache.poi.xwpf.usermodel.XWPFDocument; 

public class WordConvertPDF { 
    public static void main(String[] args) { 
     WordConvertPDF cwoWord = new WordConvertPDF(); 
     cwoWord.ConvertToPDF("D:/Test.docx", "D:/Test.pdf"); 
    } 

    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); 
     } catch (IOException ex) { 
      System.out.println(ex.getMessage()); 
     } 
    } 
} 

i słoiki:

Enjoy :)

Answer 3

używam tego kodu.

private byte[] toPdf(ByteArrayOutputStream docx) { 
    InputStream isFromFirstData = new ByteArrayInputStream(docx.toByteArray()); 

    XWPFDocument document = new XWPFDocument(isFromFirstData); 
    PdfOptions options = PdfOptions.create(); 

    //make new file in c:\temp\ 
    OutputStream out = new FileOutputStream(new File("c:\\tmp\\HelloWord.pdf")); 
    PdfConverter.getInstance().convert(document, out, options); 

    //return byte array for return in http request. 
    ByteArrayOutputStream pdf = new ByteArrayOutputStream(); 
    PdfConverter.getInstance().convert(document, pdf, options); 

    document.write(pdf); 
    document.close(); 
    return pdf.toByteArray(); 
}
