同时需要记住,keepalive不允许你为探测套接字终点(endpoint)指定一个值。所以建议开发者使用的另一种比keepalive更好的解决方案是修改超时设置套接字选项。 说白了:这个参数其实对应用层的程序而言没有什么用。可以通过应用层实现了解服务端或客户端状态,而决定是否继续维持该Socket。

Keep-Alive 是Socket TCP底层的机制，就是定期检查一下两边的连接是不是断的。但定期时间很长，以Unix为例，通常是半小时。如果不改Keep-Alive interval 的话，设置何不设置没啥区别。有时候跨路由器或交换机还不好使。。。

Socket(InetAddress address, int port) Socket(String host, int port) InetAddress类表示IP地址,其用法如下: //返回本地主机的IP地址 InetAddress addr1=InetAddress.getLocalHost(); //返回代表"222.34.5.7"的IP地址 InetAddress addr2=InetAddress.getByName("222.34.5.7"); ...
