java.net.SocketTimeoutException: Read timed out问题解决

我做的是一个投票软件,在正式投票前,我测试过很多次,都没有出现任何问题,但是正式投票过程中报了一下错误

环境说明:

一个有密码保护的局域网(器材:华为某设备),所有使用者通过ip地址访问服务器,我的电脑为服务器(数据库也在本机上),总共有42个评委,另外三个管理员,加起来就45个左右使用者。

 从错误中可以看出是由于读取超时,而造成dwr出现警告

为了解决这个异常我找了很多办法,但是归根结底是因为:客户端没有在规定的时间内把数据传给服务器,服务器为了保证服务性能,认定那个链接已失效,就出现了这个异常。
