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，此代码会给出异常:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/xmlbeans/XmlException
at l3s.readfiles.db.ReadFile.ReadFileParagraph(ReadFile.java:52)

另一个问题是，当我想读取Doc文件时，它很好地读取了某些文件，但是对于某些文件，却给出了类似的异常
Exception in thread "main" org.apache.poi.hwpf.OldWordFileFormatException: The document is too old - Word 95 or older. Try HWPFOldDocument instead?

我看到POI API在http://poi.apache.org/hwpf/index.html中支持单词6和单词95。
请有人可以解决这两个问题吗？
最佳答案
所需的核心Maven依赖关系，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，从原始源代码开始，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?");
}
