java打开word总结

在jsp中打开word,或者提取内容的一些方式:

1、用流的方式,界面呈现为:提示用户下载,或直接打开

<%@ page language="java"  contentType="application/msword; charset=gb2312"  pageEncoding="gb2312"%>
<%@page import="java.io.*"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <%@ include file="/common/page_include.jsp"%>
    <meta http-equiv="Content-Type" content="application/msword; charset=gb2312" />
</head>
    <body>
    <%
        File file = new File (request.getSession().getServletContext().getRealPath("/") +"/frame/帮助文档.docx" );
        System.out.println("=======--------") ;
        FileInputStream is = null;
        OutputStream os = null;
        try {
            request.setCharacterEncoding("iso_8859_1");
            //response.reset();
            response.setContentType("application/vnd.ms-word;charset=8859_1");
            response.setHeader("Content-disposition","attachment;filename="+"帮助文档.docx");
            is = new FileInputStream (file);
           os = response.getOutputStream();
            out.clear();
            out = pageContext.pushBody();
            byte buff[]=new byte[1024];
            int len=0;//表示实际每次读取了多少个字节
            while((len=is.read(buff))>0){
                os.write(buff, 0, len);
            }


        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                os.flush();
                is.close();


                // file.delete();


            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    %>

    </body>
</html>

2、用poi解析word中的内容,只做到提取文字,提取图片有问题,而且文字显示不是按原来word文档里的格式了。

可以参考:http://blog.csdn.net/hemingwang0902/article/details/4381598


3、java调用pageOffice来实现
