对付txt文件:
index.jsp
 <form action="doupload.jsp" method="post" enctype="multipart/form-data">
    file:<input type="file" name="file"><br>
    <input type="submit" value="upload">
    </form>
doupload.jsp
 <%
    //request.setCharacterEncoding("UTF-8");
    //String file=request.getParameter("file");//只能获取文件路径
    InputStream s=request.getInputStream();//获取文件内容
    BufferedReader br=new BufferedReader(new InputStreamReader(s));
    BufferedWriter bw=new BufferedWriter(new  FileWriter(new File(request.getRealPath(path)+System.currentTimeMillis()+".txt")));
    String content=br.readLine();
    boolean flag=false;
    while(content!=null){
     if(content.indexOf("Content-Type: text/plain")!=-1){
       br.readLine();
       content=br.readLine();      
       flag=true;
       continue;
       }
    if(!content.equals("\n")&& flag &&!content.startsWith("-----------------------------")){
       out.print(content+"<br>");
       bw.write(content+"\r\n");
       }
       content=br.readLine();
    }
