準(zhǔn)備文件：
1鱼喉、index.jsp
2秀鞭、download.jsp
3、待下載文件：“src.zip”(路徑為D:/src.zip)

String filename = "src.zip";

response.setHeader("Content-Disposition", "attachment; filename=\""

java.io.FileInputStream fileInputStream = new java.io.FileInputStream(
filepath + filename);
int i;
while ((i = fileInputStream.read()) != -1) {
out.write(i);
}
fileInputStream.close();

注：index.jsp文件很靈活锋边，超鏈接可以替換為按鈕等等；待下載文件可以多樣化编曼，壓縮包豆巨、jsp文件、圖片等等各種文件都可以掐场。
