如何使用POI api读取java中的doc和docx文件

我正在尝试读取 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，此代码给出异常：

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)

另一个问题当我想读取文档文件时，它可以很好地读取某些文件，但对于某些文件，它会给出这样的异常

    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)

我看到 POI API 支持单词 6 和单词 95http://poi.apache.org/hwpf/index.html http://poi.apache.org/hwpf/index.html。 请问有人可以解决这两个问题吗？

需要核心 Maven 依赖项，这是问题 1 的解决方案

<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>3.15</version>
        </dependency>
        <!-- For .DOCX FILES -->
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.15</version>
        </dependency>
       <!-- For .DOC FILES -->
        <dependency>
           <groupId>org.apache.poi</groupId>
            <artifactId>poi-scratchpad</artifactId>
            <version>3.9</version>
        </dependency>

对于问题2 从原始源代码来看，POI似乎不支持太旧的文档

  /**
   * This constructor loads a Word document from a specific point
   *  in a POIFSFileSystem, probably not the default.
   * Used typically to open embeded documents.
   *
   * @param directory The DirectoryNode that contains the Word document.
   * @throws IOException If there is an unexpected IOException from the passed
   *         in POIFSFileSystem.
   */
  public HWPFDocument(DirectoryNode directory) throws IOException
  {
    // Load the main stream and FIB
    // Also handles HPSF bits
    super(directory);

    // Is this document too old for us?
    if(_fib.getFibBase().getNFib() < 106) {
        throw new OldWordFileFormatException("The document is too old - Word 95 or older. Try HWPFOldDocument instead?");
    }

HWPFDocument 的源代码 https://github.com/cuba-platform/apache-poi/blob/master/poi/src/scratchpad/src/org/apache/poi/hwpf/HWPFDocument.java
