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

1.

2.

3.

4.

5.

6.

7.

8. downloadtest1

9.

10.

11.

这是页面上的连接,我传了个路径和文件名

Java代码

1. <%

2. String filename = ameter("filename");//"";

3. String filepath = ameter("filepath");//"d:";

4. int i = 0;

5. tentType("application/octet-stream");

6. der("Content-Disposition","attachment;filename = "+filename);

7. putStream fileInputStream = new putStream(filepath+filename);

8. while((i= ()) != -1){

9. (i);

10. }

11.%>

这是被调用的,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.
