NIO和JMS有什么区别(What is the difference between NIO and JMS)

据我所知Java NIO是一个API来帮助创建事件驱动的应用程序。 您在哪里使用选择器来通知您的应用程序通过SocketChannel接收到的任何数据。 JMS（Java消息传递服务）是用于在客户端之间发送/接收消息的消息传递框架。

JMS是Java NIO API的抽象吗？

As I understand Java NIO is an API to help create event-driven applications. Where you use a selector to notify your application of any data received over a SocketChannel. JMS(Java Messaging Service) is a messaging framework for sending/receiving messages between clients.

Is JMS a abstraction of Java NIO API?

NIO只代表New IO。 它是一个增强的通用Java IO软件包，它对异步IO有很多支持，但也包含其他一些增强功能，如支持通过文件名进行查询。 当您尝试执行java.io中的类不支持的操作时，您会使用它。

JMS是一个Java消息传递系统。 当需要让两个应用程序通过类似队列的系统相互通信时，可以使用它。 在底层使用NIO是否是一个实现细节，尽管用Java编写的各种JMS提供者可能会这样做。

NIO just stands for New IO. It's an enhanced general Java IO package, that has a lot of support for asynchronous IO, but also contains quite a few other enhancements, like support for grepping through filenames. You would use it when you're trying to do something that's not supported by the classes in java.io.

JMS is a java messaging system. You can use it when you need to have two applications talk to one another over a queue-like system. Whether or not it uses NIO under the hoods is an implementation detail, though various JMS providers written in Java probably do.
