使用APACHE POI处理docx文件

Question

我正在尝试从数据库检索docx，并尝试通过检查其内容来对其进行处理。我认为mycode检索了我想要的文件，但似乎我还没有完全理解APACHE POI。我在stacktrace上遇到一个错误，说我对POI的想法有误吗？

这是我加载文件的方式：

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

您应该知道，目前MS Office文档以两种不同的格式存在：一种是2007年之前版本的MS Office使用的旧格式（例如“ .doc”或“ .xls”），另一种是基于XML的格式。较新版本使用的格式（例如“ .docx”或“ .xlsx”）。

Apache POI中有处理不同格式的不同部分。用于处理旧MS Office格式文件的密钥类的名称通常以“ H”开头，用于处理基于XML格式文件的密钥类的名称以“ X”开头。

因此，在示例中，为了处理新格式，您应该使用XWPFDocument而不是HWPFDocument：

XWPFDocument doc = new XWPFDocument(is);
