POI或docx4j可以读取密码保护的Word文档吗？

Question

我遇到与POI有关的问题，希望得到一些帮助。

我有一个个人日记，我已经保存了多年，每天将日记条目存储到存储在年份文件夹中的Word .doc中。我添加一个密码来打开每个密码，所以它们都被加密。

我想使用Lucene来索引整个集合，以便更好地搜索（例如，“我最后一天写了多少我喜欢燕麦片？”）。

第一步是使用POI来读取一个Word.doc文件，但是我无法下载硬币，因为它无法读取我的加密文件。

我写这个类：

package model; 

import org.apache.commons.logging.Log; 
import org.apache.commons.logging.LogFactory; 
import org.apache.poi.hwpf.HWPFDocument; 
import org.apache.poi.hwpf.model.DocumentProperties; 
import org.apache.poi.poifs.crypt.Decryptor; 
import org.apache.poi.poifs.crypt.EncryptionInfo; 
import org.apache.poi.poifs.dev.POIFSLister; 
import org.apache.poi.poifs.filesystem.POIFSFileSystem; 

import java.io.File; 
import java.io.FileInputStream; 
import java.io.IOException; 
import java.security.GeneralSecurityException; 
import java.util.LinkedList; 
import java.util.List; 

/** 
* JournalReader class that's the heart of my efforts to finally read, parse, index, and search my journal. 
* @author Michael 
* @link 
* @since 8/19/12 3:48 PM 
*/ 
public class JournalReader { 
    public static final Log LOGGER = LogFactory.getLog(JournalReader.class); 
    public static final String DEFAULT_PASSWORD = "journal"; 


    public static void main(String[] args) { 
     if (args.length > 0) { 
      try { 
       POIFSLister.viewFile(args[0], true); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    } 
    public List<JournalEntry> readEntries(File journalFile) throws IOException, GeneralSecurityException { 
     List<JournalEntry> journalEntries = new LinkedList<JournalEntry>(); 
     if (journalFile != null) { 
      POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream(journalFile)); 
      // Exception is thrown after info line is executed. 
      EncryptionInfo info = new EncryptionInfo(fs); 
      Decryptor decryptor = Decryptor.getInstance(info); 
      decryptor.verifyPassword(DEFAULT_PASSWORD); 
      HWPFDocument journalDocument = new HWPFDocument(decryptor.getDataStream(fs)); 
      DocumentProperties documentProperties = journalDocument.getDocProperties(); 
     } 
     return journalEntries; 
    } 
} 

我有一个JUnit测试尝试一下：

import model.JournalEntry; 
import model.JournalReader; 
import org.junit.Assert; 
import org.junit.Test; 

import java.io.File; 
import java.io.IOException; 
import java.security.GeneralSecurityException; 
import java.util.List; 

/** 
* JournalReaderTest JUnit test for JournalReader 
* @author Michael 
* @link 
* @since 8/19/12 8:46 PM 
*/ 
public class JournalReaderTest { 

    @Test 
    public void testReadEntries() throws IOException, GeneralSecurityException { 
     JournalReader journalReader = new JournalReader(); 
     String journalFilePath = "C:\\Users\\Michael\\Documents\\Stuff To Back Up\\Journal\\1994\\AUG94.doc"; 
     File journalFile = new File(journalFilePath); 
     List<JournalEntry> journalEntries = journalReader.readEntries(journalFile); 
     Assert.assertNotNull(journalEntries); 
     Assert.assertTrue(journalEntries.size() > 0); 
    } 
} 

当我运行JUnit测试中，我得到这个堆栈跟踪：

POI文档和javadocs一直没用。在我考虑切换到docx4j的时候，我感到很沮丧。这意味着将我所有的.doc文件翻译为.docx（当然，经过适当的备份后）。

我想知道是否有人使用docx4j读取加密的，受密码保护的文件。任何人？我只是想肯定的答案告诉我，值得一提。

如果任何人都能看到我在做POI问题，我也很高兴知道这一点。谢谢。

Answer 1

披露：我对docx4j工作

docx4j的OpcPackage包含：

/** 
* Convenience method to create a WordprocessingMLPackage 
* or PresentationMLPackage 
* from an existing File (.docx/.docxm, .ppxtx or Flat OPC .xml). 
* 
* @param docxFile 
*   The docx file 
* @param password 
*   The password, if the file is password protected (compound) 
*    
* @Since 2.8.0   
*/ 
public static OpcPackage load(final java.io.File docxFile, String password) throws Docx4JException 

这应该照顾受密码保护的部分。

我自己也没有玩过很多关于docx文件的加密/解密。
