netty s application

Reprinted from http://blog.csdn.net/kobejayandy/article/details/11836813Netty provides asynchronous, event-driven network application frameworks and tools for rapid development of high-performance, high-reliability network servers and client programs [official definition], with the following in the overall context:1. Provides rich protocol codec support2. Implement your own buffer system to reduce the cost of replication3. Implementation of the entire

is as follows:Runtime.getruntime (). exit (0);When the virtual machine exits, the underlying automatically detects whether the user has registered the Shutdownhook task, and if so, automatically pulls up the Shutdownhook thread, executes its run method, and the user only needs to perform the resource release operation in Shutdownhook, the sample code is as follows:Class Shutdownhook implements runnable{@Overridepublic void Run () {System.out.println ("Shutdownhook Execute start ...") ; System.o

Tenth chapter, Chapter 11th prefaceFor the network, the data is just the raw byte sequence, but our program organizes these bytes in a way that we can understand, and we generally call this information "information", Convert the information into bytes or replace the bytes in the network with the information we can read these are among the most common tasks in our network transmission, and you may need to work in a standard format or protocol, such as an FTP protocol or a Telnet protocol, or a pr

Netty is a Web application framework based on Java NIO. Netty is a NIO client-server(client server) framework that uses Netty to quickly develop network applications such as server and client protocols. Netty provides a new way to develop a Web

The introduction of UDP is not explained here.UDP does not have an actual link between the client and the server, so there is no need to set handler for the connection (Channelpipeline), compared to TCP.Service side:1 Public voidRunintPortthrowsexception{2Eventloopgroup Group =NewNioeventloopgroup ();3 Try {4Bootstrap B =NewBootstrap ();5B.group (Group).

processing.Channelhandler is a piece of code that executes business logic that passes through Channelpipeline.There are two directions of traffic in the Netty, Inbound (Channelinboundhandler) and outbound (Channeloutboundhandler), if the data is from the application to the remote host, it is outbound (outbound), If it is from the remote host to the application i

NIO was originally the abbreviation for New input/output. However, the Java API has been around for a long time and it is no longer new.Now commonly used abbreviations to represent nonblocking I/O (non-blocking I/O). On the other hand, the general (including the author) refers to blocking I/OOIO or Old input/output. You may also encounter normal I/O.We have shown an example of I/O blocking in Java. Figure 1.1 shows how the method must be extended to handle multiple connections: to each connectio
