挺好用的。

原文：

Jsp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
