Spring 集成 TCP - 完全关闭监听套接字的好方法是什么
Spring Integration TCP - What is a good way to close listening socket completely
使用这个选项好吗
AbstractServerConnectionFactory.closeCOnnection(ClientConnId)。我正在使用它，但发生的事情是，经过几天的处理，服务器开始出现 "too many open files" 错误。我通过 运行 命令 "lsof" 和“/proc/pid/fd” 调查了这个问题，它向我展示了大约 280 个套接字和管道的文件描述符
*(I have pasted the file descriptor outcome at the end of the question thread)*.
活动 tcp 连接数为 12，但文件描述符远远超过活动连接数并且每天都在增长。
我的应用程序确实打开了 12 个文件，但文件的文件描述符计数没有增长，只有 12，这是预期的计数。
我觉得罪魁祸首是没有正确关闭的客户端套接字。
使用的示例代码
AbstractServerConnectionFactory.closeCOnnection(ClientConnId)
AbstractServerConnectionFactory connFactory = (AbstractServerConnectionFactory) applicationContext.getBean("server");
connFactory.closeConnection(clientConnId);
我从 Spring TCP 消息头中获取客户端连接 ID "IpHeaders.CONNECTION_ID"
在我的应用程序中，客户端连接到服务器套接字并发送命令，服务器套接字通过客户端建立的 TCP 连接相应地使用来自文件的数据回复命令。客户端必须每两秒向服务器套接字发送一个文本 "alive"。如果这个"alive"没有被服务器接收到，它应该
断开此客户端 connection.For 信息，我的应用程序中的 TCP 服务器套接字需要大约 3 个 tcp 客户端连接。并且如果任何客户端未能发送 "alive" 命令，则服务器套接字必须终止该连接。
我已经看到另一种关闭连接的解决方案抛出 SoftEndOfStreamException。但是这个异常似乎关闭了完整的服务器套接字。我只想关闭一个客户端连接，即无法发送 alive 命令的连接。
throw new SoftEndOfStreamException

使用它的 ID 关闭套接字应该完全关闭它。
但是，只需设置soTimeout 属性，操作系统将通知框架，如果在此期间没有收到数据，框架将关闭套接字。
throw new SoftEndOfStreamException
我不确定你在哪里做的，但我想不出它会关闭服务器套接字的场景。
该异常只能从反序列化器中抛出（当它检测到消息之间的套接字关闭时）。
使用这个选项好吗
AbstractServerConnectionFactory.closeCOnnection(ClientConnId)。我正在使用它，但发生的事情是，经过几天的处理，服务器开始出现 "too many open files" 错误。我通过 运行 命令 "lsof" 和“/proc/pid/fd” 调查了这个问题，它向我展示了大约 280 个套接字和管道的文件描述符
*(I have pasted the file descriptor outcome at the end of the question thread)*.
活动 tcp 连接数为 12，但文件描述符远远超过活动连接数并且每天都在增长。
我的应用程序确实打开了 12 个文件，但文件的文件描述符计数没有增长，只有 12，这是预期的计数。 我觉得罪魁祸首是没有正确关闭的客户端套接字。
使用的示例代码
AbstractServerConnectionFactory.closeCOnnection(ClientConnId)
AbstractServerConnectionFactory connFactory = (AbstractServerConnectionFactory) applicationContext.getBean("server");
connFactory.closeConnection(clientConnId);
我从 Spring TCP 消息头中获取客户端连接 ID "IpHeaders.CONNECTION_ID"
在我的应用程序中，客户端连接到服务器套接字并发送命令，服务器套接字通过客户端建立的 TCP 连接相应地使用来自文件的数据回复命令。客户端必须每两秒向服务器套接字发送一个文本 "alive"。如果这个"alive"没有被服务器接收到，它应该 断开此客户端 connection.For 信息，我的应用程序中的 TCP 服务器套接字需要大约 3 个 tcp 客户端连接。并且如果任何客户端未能发送 "alive" 命令，则服务器套接字必须终止该连接。
我已经看到另一种关闭连接的解决方案抛出 SoftEndOfStreamException。但是这个异常似乎关闭了完整的服务器套接字。我只想关闭一个客户端连接，即无法发送 alive 命令的连接。

使用它的 ID 关闭套接字应该完全关闭它。
但是，只需设置soTimeout 属性，操作系统将通知框架，如果在此期间没有收到数据，框架将关闭套接字。
throw new SoftEndOfStreamException
我不确定你在哪里做的，但我想不出它会关闭服务器套接字的场景。
该异常只能从反序列化器中抛出（当它检测到消息之间的套接字关闭时）。
