    public static void main(String[] args) throws Throwable {
        final String path = "G:\\doc\\";
        final String file = "客户需求文档.doc";
InputStream input = new FileInputStream(path + file);

html转word:

String body = this.getContent(bodyIs);
String css = this.getContent(cssIs);
//拼一个标准的HTML格式文档
String content = "" + body + "";
InputStream is = new ByteArrayInputStream(content.getBytes("GBK"));
OutputStream os = new FileOutputStream("f:\\1.doc");
    this.inputStreamToWord(is, os);
}

/**
 * 把is写入到对应的word输出流os中
 * 不考虑异常的捕获,直接抛出
 * @param is
* @param os
* @throws IOException
 */
private void inputStreamToWord(InputStream is, OutputStream os) throws IOException {
    POIFSFileSystem fs = new POIFSFileSystem();
//对应于org.apache.poi.hdf.extractor.WordDocument
fs.createDocument(is, "WordDocument");
fs.writeFilesystem(os);
os.close();
is.close();
}

/**
 * 把输入流里面的内容以UTF-8编码当文本取出。
 * 不考虑异常,直接抛出
 * @param ises
* @return
* @throws IOException
 */
private String getContent(InputStream... ises) throws IOException {
    if (ises != null) {
        StringBuilder result = new StringBuilder();
BufferedReader br;
String line;
        for (InputStream is : ises) {
            br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            while ((line=br.readLine()) != null) {
                result.append(line);
}
        }
        return result.toString();
}
    return null;
}
