First of all, we know that in NIO network programming model, IO operations are directly related to channel, such as client request connection, or sending data to the server, the server must obtain this data from the client channel. So what is Channel Pipeline? In fact, this channel Pepiline is a component added by netty to the native channel. A ...

I. Preface Dubbo's Extension Loader is an important component of "micro-kernel + plug-in" implementation, which is based on the java spi mechanism but provides the following extensions: jdk spi only obtains all implementations by interface class name, while Extension Loader obtains an implementation by interface class name and key ...

Http HTTP protocol is the abbreviation of Hyper Text Transfer Protocol (HTTP), which is used to transfer hypertext from WWW:World Wide Web server to local browser. HTTP is a communication protocol based on TCP/IP to transfer data (HTML files, image files, query results, etc.). HTTP is an object-oriented protocol belonging to the ...

netty Literacy > The purpose of this article is to have a general impression of netty, so that we can have a deep understanding of some basic concepts before netty. brief introduction NIO Communication Framework The number of connections supported by a single point is related to machine memory (about 10W + 1G memory), not to the maximum num ...

EventLoop In introducing the initialization and start-up process of Bootstrap, we touched NioEventLoopGroup several times. To understand this class, we also need to understand netty's thread model. NioEventLoopGroup can be understood as a set of threads, each of which can handle io events generated by multiple channel s independently. Initializ ...

The code snippet is as follows: // startup server ServerConnectionFactory sf = new ServerConnectionFactory(); sf.setCharset(system.getCharset()); sf.setIdleTimeout(system.getIdleTimeout()); server = new NIOAcceptor(NAME + "Server", system.getServerPort(), sf); server.setProcessors(processors); server.start(); See how to do this, t ...

In the last article, we let iOS devices discover Android devices via AirTunes link. In this article, we will complete iOS devices connected to Android devices via AirTunes. 3. Implementing iOS devices connected to Android devices via AirTunes 1. Use netty to construct a server and set the basic configuration. final ServerBootstrap airTunesBoo ...

What is ByteBuf? The Java NIO provides the ByteBuffer class as a byte buffer, but the use of ByteBuffer is complex, especially requiring flip() to switch between read and write So Netty redesigned a byte buffer ByteBuf with the following features: Extensibility Defines read and write indexes, so flip() switching is not required f ...

1. Future in Netty Future in Netty inherits ava.util.concurrent.Future, while Future in Java primarily runs or cancels tasks, and Netty adds more functionality. public interface Future<V> extends java.util.concurrent.Future<V> { boolean isSuccess(); //Returns true if and only if the i/o operation completes suc ...
