java是一个总是由远程主机引起的EOFEException吗？

2 周 Questions & Answers

我有一个客户端，它通过socket向主机发送数据。偶尔我会得到java.io.EOFException

问题是：我怎么知道是谁导致插座关闭的？由于远程主机关闭了socket，是否总是引发该异常

或者也可能是内部网络连接问题？还是我的ISP

    The question is: how can I know who caused the socket close? Is that exception always raised because the remote host closed the connection?

    对。任何其他都应该导致连接重置或读取超时，这就是JRE类本身的行为方式

    然而，错误信息的措辞并不令人鼓舞“Connection is closed”（连接已关闭）可能意味着您正在使用的库在使用已被本地应用程序关闭的连接时错误地抛出EOFException。您需要查看源代码才能确定
