不好意思，最近工作忙，没上来看贴．我在这把代码给大家下：
Java代码
<meta?http-equiv="Content-Type"?content="text/html;?charset=gbk">
<HTML>
<HEAD>
</HEAD>
<BODY>
<a?href?=?"download1.jsp?filepath=d:\\&filename=1a.txt"?>downloadtest1</a>
</BODY>
</HTML>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<HTML>
<HEAD>
</HEAD>
<BODY>
<a href = "download1.jsp?filepath=d:\\&filename=1a.txt" >downloadtest1</a>
</BODY>
</HTML>
这是页面上的连接，我传了个路径和文件名
Java代码
<%?
?String?filename?=?request.getParameter("filename");//"1a.txt";?
?String?filepath?=?request.getParameter("filepath");//"d:\\";
int?i?=?0;
?response.setContentType("application/octet-stream");
?response.setHeader("Content-Disposition","attachment;filename?=?"+filename);?
?java.io.FileInputStream?fileInputStream?=?new?java.io.FileInputStream(filepath+filename);
?while((i=?fileInputStream.read())?!=?-1){
out.write(i);
?}
%>
<%
String filename = request.getParameter("filename");//"1a.txt";
String filepath = request.getParameter("filepath");//"d:\\";
int i = 0;
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename = "+filename);
java.io.FileInputStream fileInputStream = new java.io.FileInputStream(filepath+filename);
while((i= fileInputStream.read()) != -1){
out.write(i);
}
%>
这是被调用的download1.jsp，这个jsp就是执行直接下载文件的不管是txt还是word文档都可以直接下载
这个东东是我在一个专业编程杂志的网站花３块钱买的，嘿嘿．没办法，项目急用，今天上来看到有人需要赶紧发出来，希望３，４楼还能看到．
