问题描述
在C/Linux中，很容易为每个 KEEPALIVE tcp连接独立地设置不同的套接字选项值.
In C/Linux, it's easily to set different value about those socket options for every KEEPALIVE tcp connection independently.
TCP_KEEPIDLE(从Linux 2.4开始) 如果已在套接字上设置套接字选项SO_KEEPALIVE，则在TCP开始发送保持活动探测之前，连接需要保持空闲时间(以秒为单位). 此选项不应在旨在可移植的代码中使用.
TCP_KEEPIDLE (since Linux 2.4) The time (in seconds) the connection needs to remain idle before TCP starts sending keepalive probes, if the socket option SO_KEEPALIVE has been set on this socket. This option should not be used in code intended to be portable.
TCP_KEEPINTVL(从Linux 2.4开始) 各个keepalive探针之间的时间(以秒为单位).此选项不应在旨在可移植的代码中使用.
TCP_KEEPINTVL (since Linux 2.4) The time (in seconds) between individual keepalive probes. This option should not be used in code intended to be portable.
在netty或java中，如何为套接字设置三个套接字选项?我知道没有可移植的方法来解决它，但是只有在Linux中，我才能设置这些套接字选项吗?
In netty or java, how to set the three socket options for socket? I know there is no portable way to solve it, but only in Linux, can I set those socket options?
推荐答案
给出的链接实际上并没有告诉您如何使用JNA来实现它.花了一段时间在SO上四处寻找解决方案之后，我编写了自己的库.您可以在此处找到它.
The link given doesn't actually tell you how to use JNA to implement it. Having spent a while digging around on SO to find solutions, I wrote my own library. You can find it here.
