如何在Java中仅通过socket通信实现流控制？

Question

我目前正在使用socket用Java编写一个简单的客户机/服务器。我希望服务器根据通过socket从客户端接收的不同“命令”和/或序列化对象做出决策，反之亦然

比如：

[Receive Command 'DoSomething' From Client]
[Call Method 'DoSomething' on the Server]
[Send result/status to Client]
etc...

使用普通socket通信（可能是序列化）是否有这样的流控制约定？我应该在Java中使用RMI吗

Answer 1

我推荐KryoNet做任何RMI类型的事情，而不需要RMI的开销和它带来的不灵活

http://code.google.com/p/kryonet/

KryoNet makes the assumptions that it will only be used for client/server architectures and that KryoNet will be used on both sides of the network. Because KryoNet solves a specific problem, the KryoNet API can do so very elegantly.

The Apache MINA project is similar to KryoNet. MINA's API is lower level and a great deal more complicated. Even the simplest client/server will require a lot more code to be written. MINA also is not integrated with a robust serialization framework and doesn't intrinsically support RMI.

The Priobit project is a minimal layer over NIO. It provides TCP networking similar to KryoNet, but without the higher level features. Priobit requires all network communication to occur on a single thread.

The Java Game Networking project is a higher level library similar to KryoNet. JGN does not have as simple of an API.

没有。如果使用套接字创建客户机/服务器通信，则必须定义自己的协议以及适用于该协议的规则

RMI可以通过执行特定的对象方法来简化这一步骤。我最近几年听说的rmi服务器的初始设置等方面的交易并不像过去那样困难
