action里
String filePath ="文件的路径和文件名字";
resp.reset();//resp==response
if (filePath.endsWith(".doc") || filePath.endsWith(".rtf")) {
resp.setContentType("application/msword");
resp.setHeader("Content-disposition", "inline; filename="
+ URLEncoder.encode(fileName, "UTF-8"));
} else if (filePath.endsWith(".pdf")) {
resp.setContentType("application/pdf");
resp.setHeader("Content-disposition", "inline; filename="
+ URLEncoder.encode(fileName, "UTF-8"));
} else if (filePath.endsWith(".xls")) {
resp.setContentType("application/vnd.ms-excel");
resp.setHeader("Content-disposition", "inline; filename="
+ URLEncoder.encode(fileName, "UTF-8"));
} else {
resp.setContentType("application/x-msdownload");
resp.setHeader("Content-disposition",
"attachment; filename="
+ URLEncoder.encode(fileName, "UTF-8"));
}
File file = new File(filePath);     if(!file.exists()) 
     file = new File(req.getSession().getServletContext().getRealPath("/"+ filePath));
FileInputStream in = org.apache.commons.io.FileUtils
.openInputStream(file);
ServletOutputStream sout = resp.getOutputStream();
int filesize = org.apache.commons.io.IOUtils.copy(in, sout);
sout.close();
