Java如何使用Apache POI替换Microsoft Word文档中的文本？
下面的代码段向您展示了如何使用ApachePOI库替换MicrosoftWord文档中的字符串。下面的类具有openDocument()，saveDocument()和replaceText()三种方法。
替换文本的例程在replaceText()方法中实现。此方法将HWPFDocument、要查找的字符串和替换它的字符串作为参数。openDocument()打开Word文档。文本替换完成后，Word文档将通过saveDocument()方法保存。
这是完整的代码片段。它将o用0源文档中的字符替换每个字符，lipsum.doc然后将结果保存到名为new-lipsum.doc的新文档中。

if (text.contains(findText)) {

}
}
}
}
return doc;
}
private HWPFDocument openDocument(String file) throws Exception {
URL res = getClass().getClassLoader().getResource(file);
HWPFDocument document = null;
if (res != null) {
document = new HWPFDocument(new POIFSFileSystem(
new File(res.getPath())));
}

}
private void saveDocument(HWPFDocument doc, String file) {
try (FileOutputStream out = new FileOutputStream(file)) {
doc.write(out);
} catch (IOException e) {
e.printStackTrace();
}
