java读取word的几种方式

1.使用apache poi组件

   先到http://poi.apache.org/index.html去下载poi-bin-3.2-FINAL-20081019.zip压缩包，把里面的三个jar加入工程中。下面写个测试servlet类。比如请求为href="/TestPOI/readword.do?doc=F:/test.doc"

    public class ReadwordServlet extends HttpServlet {
    static final private String CONTENT_TYPE = "text/html; charset=gb2312";
    public void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
            response.setContentType(CONTENT_TYPE);
            response.setHeader("Content-Disposition", "test.doc");
            String doc = request.getParameter("doc");
           
            String text = null;
            try {
                text = readDoc(doc);
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            PrintWriter out = response.getWriter();
            result(request, out, text);
    }
    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
            doPost(request,response);
    }
    private void result(HttpServletRequest request, PrintWriter out, String text)
    throws ServletException, IOException {
        out.println("<h3>DOCBEGIN</h3><br/>");
        out.println(text);
        out.println("<br/><h3>DOCEND</h3>");
        out.close();
    }

///使用POI的WordExtractor类进行读取word内容

   private String readDoc(String doc) throws Exception{

      FileInputStream in = new FileInputStream(new File(doc));

       WordExtractor extrator = new WordExtractor(in);

      String text = extrator.getText();
      return text;
   }

}

2. 使用POI的拓展包tm-extractors-0.4.jar

http://mirrors.ibiblio.org/pub/mirrors/maven2/org/textmining/tm-extractors/0.4/去下载并加入工程中，它一个就够了，不用POI.

  替换掉原先readDoc(String doc)方法就可以。

    private String readDoc(String doc) throws Exception{
        FileInputStream in = new FileInputStream(new File(doc));
        WordExtractor extrator = new WordExtractor();
        String text = extrator.extractText(in);
        return text;
    }

3.  使用FileInputStream流的方式:

  用下面替换掉CONTENT_TYPE(因为流对word格式不熟悉无法自己处理，所以只能使用word格式了)

static final private String CONTENT_TYPE = "application/msword; charset=gb2312";

用下面替换doPost方法内容

response.setContentType(CONTENT_TYPE);
            response.setHeader("Content-Disposition", "test.doc");
            String doc = request.getParameter("doc");

   FileInputStream fin = new FileInputStream(doc);
           OutputStream out = response.getOutputStream();
           byte[] bs = new byte[2048];
           for(int i=fin.read(bs); i>-1; i=fin.read(bs)){
               out.write(bs, 0, i);
           }
           fin.close();
           out.close();

4.  可以使用中间件，效果当然很好，但是要花钱。如：科翰软件的微软office网路中间件
    http://www.kehansoft.com/soaoffice/doclist.asp
    或者NTKO Office也可以。

现在可以使用PageOffice了，这是一个代替soaoffice的产品，可以兼容目前最新的操作系统和office环境。www.zhuozhengsoft.com的下载中心可以下载免费的试用开发包，demo也比较多。
