有一个很好的Java网络库吗？ [英] Is there a good Java networking library?

问题描述

我目前正在搜索Java网络库。我想要做的是将XML，JSON或其他序列化消息从客户端发送到另一个客户端和/或客户端到服务器。

我的第一次尝试是创建一个POJO对于每条消息，加上一个MessageWriter用于发送，MessageReader用于接收它。加上套接字和错误处理。这是一个很容易出错的工作。

我正在寻找的是一个从套接字中抽象出来的更高级别的库。此外，它应支持消息的代码生成等内容。

Google的协议缓冲区（ http://code.google.com/apis/protocolbuffers/ ）看起来很有前景。但有其他选择吗？重点不在于速度或安全性（目前），它应该可靠且工作时间少。

解决方案

啊......陷阱。
但不是使用代码gen。如果你在两端都有Java，你可以使用简单的对象序列化来编组和取消编组吗？如果需要考虑性能和/或消息大小，可以使Message类可外部化。

之前我没有看过Protobuf。看起来很不错。使用它，你只需要一个传输方法。

I'm currently searching for a Java networking library. What I want to do is sending XML, JSON or other serialized messages from a client to another client and/or client to server.

My first attempt was to create an POJO for each message, plus a MessageWriter for sending and a MessageReader for receiving it. Plus socket and error handling. Which is quite a lot of error prone work.

What I'm looking for is a a higher level library which abstracts from sockets. Furthermore it should supports something like code generation for the messages.

Google's Protocol Buffers (http://code.google.com/apis/protocolbuffers/) looks promising. But are there alternatives? The emphasis is not on speed or security (at the moment), it is just supposed to work reliable and with a low amount of implementation time.

解决方案

Ah... gotcha. But rather than using code gen. to marshall and unmarshall, if you have Java on both ends, could you use simple object serialization ? If performance and/or message size is a concern, you could make your Message class externalizable.

I had not looked at Protobuf before. Looks pretty decent. Using that, you would then just need a transmission method.
