Question

我已经阅读了doc文件，现在我正在尝试阅读docx文件内容。当我搜索样本代码时，我发现很多，没有任何效果。检查代码以供参考......

import java.io.*;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.text.Document;
import com.itextpdf.text.Paragraph;

public class createPdfForDocx {

public static void main(String[] args) {
InputStream fs = null;  
    Document document = new Document();
    XWPFWordExtractor extractor = null ;

try {

    fs = new FileInputStream("C:\\DATASTORE\\test.docx");
    //XWPFDocument hdoc=new XWPFDocument(fs);
    XWPFDocument hdoc=new XWPFDocument(OPCPackage.open(fs));
    //XWPFDocument hdoc=new XWPFDocument(fs);
    extractor = new XWPFWordExtractor(hdoc);
    OutputStream fileOutput = new FileOutputStream(new       File("C:/DATASTORE/test.pdf"));
    PdfWriter.getInstance(document, fileOutput);
    document.open();
    String fileData=extractor.getText();
    System.out.println(fileData);
    document.add(new Paragraph(fileData));
    System.out.println(" pdf document created");
        } catch(IOException e) {
            System.out.println("IO Exception");
             e.printStackTrace();
          } catch(Exception ex) {
             ex.printStackTrace();
           }finally {  
                document.close();  
           } 
 }//end of main()
}//end of class

对于上面的代码我得到以下例外：

请帮忙谢谢

Answer 1

Apache POI FAQ涵盖了这一点！你想要的条目是我正在使用poi-ooxml-schemas jar，但我的代码失败了“java.lang.NoClassDefFoundError：org / openxmlformats / schemas / something ”

简短的回答是为完整的poi-ooxml-schemas jar切换ooxml-schemas-1.1 jar。完整的答案是given in the FAQ
