Answer 1

java.net.SocketTimeoutException: read is alrady timed out

表示读取超时

给个示例
socket.setSoTimeout(1000); // 这里是1秒，最好先不设置
InputStream is = socket.getInputStream();
is.read();

第一行设置了一个超时时间，这个时间时执行is.read()的超时时间
请检查下，你是否将这个时间设置太小了？？
根据你的异常日志，是在web应用的Request流中读取数据，估计就是上传文件，然后程序读取流，保存文件，所以时间设置过小，文件还在传输，时间就到了，因此就超时

另外种情况就是，网络通讯时，时间设置过小，流读取未完毕就超时了

Answer 2

网络通讯中，超时是很正常的事情，要找到错误原因

追问

生产日志狂刷，都是这个异常，还不知道从哪入手，从这个异常里也看不出哪里造成的
