java文件下载设置中文名称的实例(response.addHeader)

实例如下：

protected void dopost(httpservletrequest request, httpservletresponse response)
   throws servletexception, ioexception {
   string browser = "";
   string filename = "测试.txt";
   try {
    browser = request.getheader("user-agent");
    if (-1 < browser.indexof("msie 6.0") || -1 < browser.indexof("msie 7.0")) {
     // ie6, ie7 浏览器
     response.addheader("content-disposition", "attachment;filename="
       + new string(filename.getbytes(), "iso8859-1"));
    } else if (-1 < browser.indexof("msie 8.0")) {
     // ie8 
     response.addheader("content-disposition", "attachment;filename="
       + urlencoder.encode(filename, "utf-8"));
    } else if (-1 < browser.indexof("msie 9.0")) {
     // ie9
     response.addheader("content-disposition", "attachment;filename="
       + urlencoder.encode(filename, "utf-8"));
    } else if (-1 < browser.indexof("chrome")) {
     // 谷歌
     response.addheader("content-disposition",
       "attachment;filename*=utf-8''" + urlencoder.encode(filename, "utf-8"));
    } else if (-1 < browser.indexof("safari")) {
     // 苹果
     response.addheader("content-disposition", "attachment;filename="
       + new string(filename.getbytes(), "iso8859-1"));
    } else {
     // 火狐或者其他的浏览器
     response.addheader("content-disposition",
       "attachment;filename*=utf-8''" + urlencoder.encode(filename, "utf-8"));
    }
   } catch (exception e) {
    e.printstacktrace();
   }
   inputstream in = new fileinputstream("d:\\test.txt");//获取文件输入流
    int len = 0;
    byte[] buffer = new byte[1024];
    outputstream out = response.getoutputstream();
    while ((len = in.read(buffer)) > 0) {
     out.write(buffer,0,len);//将缓冲区的数据输出到客户端浏览器
    }
    in.close();
    out.flush();
    out.close();
 }

判断各个浏览器,然后进行解码和加码。
