使用它是否是个好选择
AbstractServerConnectionFactory.closeCOnnection（ClientConnId）。我正在使用此功能，但是发生的情况是服务器处理几天后开始出现“打开的文件太多” 错误。我通过运行命令“ lsof”和“ / proc / pid / fd”调查了该问题，该命令向我显示了有关套接字和管道的280个文件描述符
*(I have pasted the file descriptor outcome at the end of the question thread)*.
活动tcp连接数为12 ，但文件描述符的数量远远超过活动连接数和每天增长的数量。
我的应用程序确实打开了12个文件，但是文件的文件描述符计数没有增加，仅为12，这是预期的计数。 我认为罪魁祸首是客户端套接字未正确关闭。
使用的示例代码
AbstractServerConnectionFactory.closeCOnnection(ClientConnId)
AbstractServerConnectionFactory connFactory = (AbstractServerConnectionFactory) applicationContext.getBean("server");
connFactory.closeConnection(clientConnId);
我从Spring TCP消息标题“ IpHeaders.CONNECTION_ID”中获取了客户端连接ID
在我的应用程序中，客户端连接到服务器套接字，并通过客户端建立的TCP连接向服务器套接字发送命令，服务器套接字相应地从文件中回复数据。客户端必须每两秒钟向服务器套接字发送一个文本“有效”。如果未收到此“活动”服务器，则应 断开此客户端连接。对于“信息”，我的应用程序中的TCP服务器套接字大约需要3个tcp客户端连接。如果客户端中的任何一个未能发送“活动”命令，则服务器套接字必须终止该连接。
我已经看到了另一种通过抛出SoftEndOfStreamException 来关闭连接的解决方案。但是此异常似乎关闭了整个服务器套接字。我只想关闭一个客户端连接，而该客户端连接无法发送活动命令。
throw new SoftEndOfStreamException

答案 0 :(得分：1)
使用其ID关闭套接字应将其完全关闭。
但是，只需设置soTimeout属性，操作系统就会通知该框架，如果在该时间内没有收到数据，它将关闭套接字。
引发新的SoftEndOfStreamException
我不确定您在哪里进行操作，但是我无法想到会关闭服务器套接字的情况。
仅当从反序列化器（当它检测到消息之间的套接字关闭）时才抛出该异常。
