推荐答案

java.io.IOException：通过对等方重置连接

java.io.IOException: Connection reset by peer

另一方在交易中突然中止了连接。这可能有许多原因，无法从服务器端控制。例如。最终用户决定关闭客户端或突然更改服务器，同时仍与服务器交互，或客户端程序崩溃，或最终用户的Internet连接中断，或最终用户的计算机崩溃等等。

The other side has abruptly aborted the connection in midst of a transaction. That can have many causes which are not controllable from the server side on. E.g. the enduser decided to shutdown the client or change the server abruptly while still interacting with your server, or the client program has crashed, or the enduser's internet connection went down, or the enduser's machine crashed, etc, etc.
