如何使用POI api读取java中的doc和docx文件

Question

我正在尝试阅读doc和docx文件.这是代码:

  static String distination="E:\\         
  static String docFileName="Requirements.docx";
 public static void main(String[] args) throws FileNotFoundException, IOException {
    // TODO code application logic here
    ReadFile rf= new ReadFile();
    rf.ReadFileParagraph(distination+docFileName);


  }
  public void ReadFileParagraph(String path) throws FileNotFoundException, IOException
    {
        FileInputStream fis;
        File file = new File(path);
        fis=new FileInputStream(file.getAbsolutePath());
           String filename=file.getName();

        String fileExtension=fileExtension(path);
        if(fileExtension.equals("doc"))
        {
             HWPFDocument document=new HWPFDocument(fis);
             WordExtractor DocExtractor = new WordExtractor(document);
             ReadDocFile(DocExtractor,filename);

        }
        else if(fileExtension.equals("docx"))
        {

            XWPFDocument documentX = new XWPFDocument(fis);            
            List<XWPFParagraph> pera =documentX.getParagraphs();
            ReadDocXFile(pera,filename);
        }
        else
        {
            System.out.println("format does not match");
        }

    }
    public void ReadDocFile(WordExtractor extractor,String filename)
    {

        for (String paragraph : extractor.getParagraphText()) {
            System.out.println("Peragraph: "+paragraph);
        }
    }
    public void ReadDocXFile(List<XWPFParagraph> extractor,String filename)
    {

        for (XWPFParagraph paragraph : extractor) {
          System.out.println("Question: "+paragraph.getParagraphText());
        }

    }
    public String fileExtension(String filename)
    {

       String extension = filename.substring(filename.lastIndexOf(".") + 1, filename.length());
       return extension;
    }

当我想读取docx文件时,此代码会出现异常:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/xmlbeans/XmlException
    at l3s.readfiles.db.ReadFile.ReadFileParagraph(ReadFile.java:52)
    at autometictagdetection.TagDetection.main(TagDetection.java:36)

另一个问题是,当我想要读取一个Doc文件时,它会很好地读取一些文件,但是对于某些文件,它会给出类似的异常

    Exception in thread "main" org.apache.poi.hwpf.OldWordFileFormatException: The               document is too old - Word 95 or older. Try HWPFOldDocument instead?
    at org.apache.poi.hwpf.HWPFDocument.<init>(HWPFDocument.java:222)

我在http://poi.apache.org/hwpf/index.html中看到POI API支持单词6和单词95 .请有人能解决这两个问题吗？

关于您的第一个问题，我想您需要参考项目中的依赖关系。

即我猜测：

poi-ooxml-schemas xmlbeans，位于 poi-ooxml-schemas-version-yyyymmdd.jar 中

（来自Apache POI 页面）。

这是 Apache XMLBeans 页面。

我无法列出您需要的每个库，但您可能可以通过 Maven 找出...
