我的要求是录制用户语音并将其保存在服务器上（同时多个用户）。这是我的代码：

in = (InputStream) request.getInputStream();                         
fos = new FileOutputStream(f1);
int read = 0;
while ((read = in.read()) != -1) {
    fos.write(read);
}
fos.close();
in.close();

尝试一次为多个用户录制语音时出现以下异常，单个用户没有出现此异常：

不要关闭 InputStream 对象。

经验法则：如果您尚未打开连接或流，请不要关闭它。

注释掉 in.close()
