Java 中是否有与 libevent 相当的工具？
我编写了一个高吞吐量服务器，它在自己的线程中处理每个请求。对于传入的请求，有时需要对一个或多个后端执行 RPC。这些后端 RPC 由单独的队列和线程池处理，这对创建的线程数和后端的最大连接数提供了一些限制（它会进行一些缓存以重用客户端并节省开销）不断地建立联系）。不过，完成所有这些后，我开始认为基于事件的架构会更有效。
在搜索过程中，我没有找到任何与 Java 的 libevent 等效的东西，但也许我没有找对地方？ Apache 的 Mina-statemachine 是我发现的最接近的东西，但它看起来比我需要的更详细，而且没有真正的可用版本。
有什么建议吗？
I've written a high-throughput server that handles each request in its own thread. For requests coming in it is occasionally necessary to do RPCs to one or more back-ends. These back-end RPCs are handled by a separate queue and thread-pool, which provides some bounding on the number of threads created and the maximum number of connections to the back-end (it does some caching to reuse clients and save the overhead of constantly creating connections). Having done all this, though, I'm beginning to think an event-based architecture would be more efficient.
In searching around I haven't found any equivalents to libevent for Java, but maybe I'm not looking in the right place? Mina-statemachine from Apache was the closest thing I found, but it looks more verbose than I need and there's no real release available.
Any suggestions?

我有点晚了，但是：
你看过 Netty 吗？
或者Grizzly。

Have you looked at Netty?
Or Grizzly.
轻量级事件系统怎么样？ :) http://www.lwes.org/ 和 http://sourceforge.net/projects/lwes/files/
How about the Light Weight Event System? :) http://www.lwes.org/ and http://sourceforge.net/projects/lwes/files/
答案似乎是否定的，尽管 Ruby EventMachine 库看起来为 JRuby 用户提供了一个 Java 实现，该实现可能可用，或者至少可以为我自己的编写提供灵感：

The answer seems to be 'no', though it looks like the Ruby EventMachine library provides a Java implementation for JRuby users that might be usable or at least serve as inspiration for writing my own:
