如何使用poi jar讀取java api中的docx文件內容

Question

我已經閱讀了doc文件，現在我正在嘗試閱讀docx文件內容。 當我搜索樣本代碼時，我發現很多，沒有任何效果。 檢查代碼以供參考......

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

對於上面的代碼我得到以下異常：

請幫忙謝謝

Answer 1

這在Apache POI FAQ中有所介紹！ 你想要的條目是我正在使用poi-ooxml-schemas jar，但我的代碼失敗了“java.lang.NoClassDefFoundError：org / openxmlformats / schemas / something ”

簡短的回答是為完整的ooxml-schemas-1.1 jar切換poi-ooxml-schemas jar。 常見問題解答中給出了完整的答案

要讀取excels或docx文件，如果你想解決錯誤，你需要添加所有的罐子然后你不會得到任何錯誤。
