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

或者NTKO Office也可以。
