Java Web Communications Without Port Forwarding

Question

我希望制作一个程序，其中两个客户端将彼此连接，并且其中一个客户端将托管服务器...两个客户端都应该能够连接到服务器...有没有办法进行此操作而无需端口转发...某种对等系统？

Answer 1

Yes, the simple solution is TURN, where all communication passes through the server (Peer A <-> Server <-> Peer B). The server has to have a public IP address to be reachable from the anywhere on the net.

Peers should initiate and keep 'alive' TCP connections to the server.

Answer 2

也许您正在寻找RMI。
