java读取word的几种方式
java读取word有几种方式？
????? 今天心血来潮，上网查了查java怎么实现word的操作，发现还真不是很多，感觉也不怎么满意。
反正写下来供大家参考下也是好的，同时也希望得到大家的指点。
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

??? 或者NTKO Office也可以。
以上也大都是通过网上学习的，也不知道有没有更好的处理方式？大家可以给点建议。
第一次用心写点东西，希望大家多给点点评。
