使用APACHE POI处理docx文件

Question

我试图从数据库中检索docx，并尝试通过检查其内容来处理它。我认为我的代码检索了我想要的文件，但似乎我没有完全理解APACHE POI。我在堆栈跟踪中遇到错误，说我错了POI有什么想法？

下面是如何加载文件：

public void loadFile(String FileName) 
{ 
    InputStream is = null; 
    try 
    { 
     //Connecting to MYSQL Database 
     Class.forName(driver).newInstance(); 
     con = DriverManager.getConnection(url+dbName,userName,password); 

     Statement stmt = (Statement) con.createStatement(); 
     ResultSet rs = stmt.executeQuery("SELECT FILE FROM doccompfiles WHERE FileName = '"+ FileName +"'"); 

     while(rs.next()) 
     { 
      is = rs.getBinaryStream("FILE"); 
     } 

     HWPFDocument doc = new HWPFDocument(is); 
     WordExtractor we = new WordExtractor(doc); 

     String[] paragraphs = we.getParagraphText(); 
     JOptionPane.showMessageDialog(null, "Number of Paragraphs" + paragraphs.length); 
     con.close(); 
    } 
    catch(Exception ex) 
    { 
     ex.printStackTrace(); 
    } 
}

Answer 1

正如你应该知道，现在有两种不同的格式存在MS Office文档：一个是旧的格式（例如“.doc”或“.xls”），另一种是新版本（例如“.docx”或“.xlsx”）使用的基于XML的格式。

Apache POI中有不同的部分处理不同的格式。用于处理旧MS Office格式文件的关键类名称通常以“H”开头，用于处理基于XML格式文件的类的名称以“X”开头。

所以，在你的例子来处理新的格式，你应该使用HWPFDocument的XWPFDocument：

XWPFDocument doc = new XWPFDocument(is);
