在java中将docx转换为pdf

java pdf ms-word apache-poi

我正在尝试将包含表格和图像的文件转换为格式化文件。docxpdf

我一直在到处寻找，但没有得到适当的解决方案，要求给出正确和正确的解决方案：

这是我尝试过的：

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());
        }
    }

}

例外：

at test.TestCon.main(TestCon.java:25)

我的要求是创建一个java代码，以正确的格式和对齐方式将现有的docx转换为pdf。

请建议。

除了VivekRatanSinha答案之外，我还想为将来需要它的人发布完整的代码和所需的jars。

法典：

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());
        }
    }
}

和 JARS：

享受:)

答案 2

您缺少一些库。

我能够通过添加以下库来运行您的代码：

    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

我已经成功地转换了一个6页长的Word文档（.docx），其中包含表格，图像和各种格式。
