Open Microsoft Word in Java

I'm trying to open MS Word 2003 document in java, search for a specified String and replace it with a new String. I use APACHE POI to do that. My code is like the following one:

我正在尝试在 Java 中打开 MS Word 2003 文档，搜索指定的字符串并将其替换为新的字符串。我使用 APACHE POI 来做到这一点。我的代码如下所示：

public void searchAndReplace(String inputFilename, String outputFilename,
            HashMap<String, String> replacements) {
    File outputFile = null;
    File inputFile = null;
    FileInputStream fileIStream = null;
    FileOutputStream fileOStream = null;
    BufferedInputStream bufIStream = null;
    BufferedOutputStream bufOStream = null;
    POIFSFileSystem fileSystem = null;
    HWPFDocument document = null;
    Range docRange = null;
    Paragraph paragraph = null;
    CharacterRun charRun = null;
    Set<String> keySet = null;
    Iterator<String> keySetIterator = null;
    int numParagraphs = 0;
    int numCharRuns = 0;
    String text = null;
    String key = null;
    String value = null;
        try {
            // Create an instance of the POIFSFileSystem class and
            // attach it to the Word document using an InputStream.
            inputFile = new File(inputFilename);
            fileIStream = new FileInputStream(inputFile);
            bufIStream = new BufferedInputStream(fileIStream);
            fileSystem = new POIFSFileSystem(bufIStream);
            document = new HWPFDocument(fileSystem);
            docRange = document.getRange();
            numParagraphs = docRange.numParagraphs();
            keySet = replacements.keySet();
            for (int i = 0; i < numParagraphs; i++) {
                paragraph = docRange.getParagraph(i);
                text = paragraph.text();
                numCharRuns = paragraph.numCharacterRuns();
                for (int j = 0; j < numCharRuns; j++) {
                    charRun = paragraph.getCharacterRun(j);
                    text = charRun.text();
                    System.out.println("Character Run text: " + text);
                    keySetIterator = keySet.iterator();
                    while (keySetIterator.hasNext()) {
                        key = keySetIterator.next();
                        if (text.contains(key)) {
                            value = replacements.get(key);
                            charRun.replaceText(key, value);
                            docRange = document.getRange();
                            paragraph = docRange.getParagraph(i);
                            charRun = paragraph.getCharacterRun(j);
                            text = charRun.text();
                        }
                    }
                }
            }
            bufIStream.close();
            bufIStream = null;
            outputFile = new File(outputFilename);
            fileOStream = new FileOutputStream(outputFile);
            bufOStream = new BufferedOutputStream(fileOStream);
            document.write(bufOStream);
        } catch (Exception ex) {
            System.out.println("Caught an: " + ex.getClass().getName());
            System.out.println("Message: " + ex.getMessage());
            System.out.println("Stacktrace follows.............");
            ex.printStackTrace(System.out);
        }
}

I call this function with following arguments:

我使用以下参数调用此函数：

HashMap<String, String> replacements = new HashMap<String, String>();
replacements.put("AAA", "BBB");
searchAndReplace("C:/Test.doc", "C:/Test1.doc", replacements);

When the Test.doc file contains a simple line like this : "AAA EEE", it works successfully, but when i use a complicated file it will read the content successfully and generate the Test1.doc file but when I try to open it, it will give me the following error:

当 Test.doc 文件包含像这样的简单行时：“ AAA EEE”，它可以成功运行，但是当我使用复杂的文件时，它将成功读取内容并生成 Test1.doc 文件，但是当我尝试打开它时，它会给我以下错误：

Word unable to read this document. It may be corrupt. Try one or more of the following: * Open and repair the file. * Open the file with Text Recovery converter. (C:\Test1.doc)

Word 无法阅读此文档。它可能是腐败的。尝试以下一种或多种方法： * 打开并修复文件。* 使用文本恢复转换器打开文件。(C:\Test1.doc)

Please tell me what to do, because I'm a beginner in POI and I have not found a good tutorial for it.

请告诉我该怎么做，因为我是 POI 的初学者，我还没有找到好的教程。

You could try OpenOffice API, but there arent many resources out there to tell you how to use it.

您可以尝试OpenOffice API，但是没有很多资源可以告诉您如何使用它。

First of all you should be closing your document.

首先，您应该关闭文档。

Besides that, what I suggest doing is resaving your original Word document as a Word XML document, then changing the extension manually from .XML to .doc . Then look at the XML of the actual document you're working with and trace the content to make sure you're not accidentally editing hexadecimal values (AAA and EEE could be hex values in other fields).

除此之外，我建议做的是将您的原始 Word 文档重新保存为 Word XML 文档，然后手动将扩展名从 .XML 更改为 .doc 。然后查看您正在处理的实际文档的 XML 并跟踪内容以确保您不会意外编辑十六进制值（AAA 和 EEE 可能是其他字段中的十六进制值）。

Without seeing the actual Word document it's hard to say what's going on.

如果没有看到实际的 Word 文档，很难说出发生了什么。

There is not much documentation about POI at all, especially for Word document unfortunately.

根本没有太多关于 POI 的文档，尤其是不幸的 Word 文档。
