(Channelhandlercontext ctx, Object msg) throws Exception { //dosome process ..... ctx.firechannelread (Job);}Note that the Firechannelread () method is used instead of the Ctx.writeandflush (...). Because, Writeandflush/write is outbound, it sends the message to the previous handler, which is then sent to the remote peer, and here is the inbound. Specific reference:Here, through ctx.firechannelread (Job), the processed results are sent to the next channel processing. Ch.pip

"Communication framework" do? The answer to this question is not so easy, we might as well look at it, instead of using Netty, to write a network program directly based on NIO, what you need to do (take the server-side TCP connection For example, here we use the reactor model): Listening port, establishing socket connection Create threads, process content Read the socket content and parse the protocol For logical process

combination of buffer objects that can aggregate multiple Bytebuffer objects, allowing the user to manipulate the combo buffer as easily as a buffer, avoiding the traditional way to merge several small buffer into a large buffer with a memory copy. The Netty file transfer uses the Transferto method, which can directly send data from the file buffer to the target channel, avoiding the traditional memory copy problem caused by the cyclic write mode

First verbose 2. If you don't know what to do with Netty. It can be a simple search to find out. I can only say that Netty is NIO. The framework, which can be used to develop distributed Java plans. Details can be done and we can try to use your imagination.Technology. It is to serve people, not the limitations of human life.With everything, let's start with a piece of code.Program apes are accustomed to th

ByteBuf in Netty to access data and how to use it. 5.1 Buffer API Netty's buffer API has two interfaces: ByteBuf ByteBufHolder When Netty uses reference-counting (reference count), it knows that Buf and other resources are safely released. Although it knows that Netty uses reference count effectively, this is automatically completed. This allows

, I have another variant of the reactor model, which is the third form of change to remove the thread pool.This is also netty.The default NiO mode. In implementation, the boss class in netty acts as mainreactor, And the nioworker class acts as subreactor (defaultThe number of nioworker instances is runtime. getruntime (). availableprocessors ()). Processing new requestsNioworker reads the received data to channelbuffer, and then triggers the channelha

If you don't know what Netty is, you can do something. That can be a simple search to find out. I can only say that Netty is a NIO framework that can be used to develop distributed Java programs. What can be done, you can try to play the imagination. Technology is to serve people and not to limit people.If you already have everything, let's start with a piece of code.

Netty: data processing process, netty Data Processing Process Netty, as an asynchronous and event-driven network communication framework, helps us quickly develop high-performance and high-reliability network services. To better use Netty to solve development problems, it is necessary to learn

resulting application.Solution SolutionsThe Netty Project is an asynchronous event-driven network application framework that enables rapid development of maintainable high-performance, high-scalability protocol server and client tools.In other words, Netty is a NIO client-server framework that enables rapid and simple development of network applications such as

implementation interface to make such a situation easier.We can make the code we write as generic as possible, without relying on some APIs that implement it. When we want to switch the mode of transmission, we do not need to spend very much effort and time to refactor the code.This chapter will describe the unified API and how to use them, and will take the Netty API and Java API to tell you why Netty is

I recently learned about the Netty framework and wrote a simple netty application to the tutorial. However, the debugging failed. I can't find the cause after reading the program and the tutorial several times, later, I wrote it again, and the server program was successfully debugged. The reason was that the @ Skip annotation was used. The code is as follows:

From a large perspective, Netty performance is mainly reflected in: 1.io threading Model using reactor mode, synchronous non-blocking. This determines that more can be done with the least amount of resources. 2. Memory 0 copies use direct caching 3. Memory pool design application memory can be reused, mainly direct memory. The internal implementation is to manage memory allocations with a binary lookup tree

Before for the sake of the mode and convenience has not dealt with the problem of sticky bag, today devoted to the time to engage in netty of sticky packet processing, to know that in high concurrency, do not handle sticky packets is not possible, the chaos of data flow will cause business crashes or something I will not say. So this question has always been a knot in my heart.The use of Netty really happy,

1. Netty IntroductionNetty is an asynchronous event-driven network application framework that enables rapid development of maintainable , High-performance, protocol-oriented servers and clients . Netty is based on NIO, so the entire netty is asynchronous , and Web applications often require a high degree of scalability
