Netty Writeandflush () method is divided into two steps, first write and then flush @Override public channelfuture Writeandflush (Object msg, Channelpromise promise) { Defaultchannelhandlercontext Next; Next = Findcontextoutbound (mask_write); Referencecountutil.touch (msg, next); Next.invoker.invokeWrite (Next, MSG, promise); Next = Findcontextoutbound (Mask_flush); Next.invoker.invokeFlush (next);

So-called Ax, so before we build the Netty game server, we need to prepare the things well.First go to Netty's official website to download the latest version of the Netty jar package, http://netty.io/downloads.html, here I downloaded the netty-5.0.0.alpha2.tar.bz2 version.Open the ZIP package and locate the Netty-5.0.

Recently saw Netty framework after a deep study of the idea, but a variety of books material is too little, seemingly only a netty in action English version can be counted on the reference, the others are not recommended to everyone. So the best information is the official website information. But Netty is a set of open-source frameworks, all of which are on GitH

Netty is a Java NiO network framework that shields the underlying network details and is very efficient. If you are developing a messaging platform recently, it is best to use netty. A good messaging platform has many details that need attention and the agreed principles that should be followed. The elegant shutdown of the platform is essential. This is mainly to avoid message loss. So how can we achieve ne

Write in front: the test and resolution of Netty concurrency problem is completely beyond my expectations, more and more things to say. So this medium, that is to say, there will be the next article. As for the discovery of the problem point, Onecoder is also trying to verify.Continue the concurrency problem. In the Java NIO Framework Netty Tutorial (11) Concurrent access test (above), we are actually testi

Before working in contact with a few open-source IM products, coupled with the use of Netty to achieve a few services, so there is the idea of using Netty to implement an IM, so in my spare time to write an IM, and like Netty of the program members to share.In view of the convenience of extension, in the service side of the http+socket combination of design, the

the IO operation is asynchronous, that is, an IO operation will not block to wait for the result of the operation, the program will continue to execute downward.In Mina, Netty, and twisted, many network IO operations are asynchronous, such as write to the other end of the network, connect to the client connection server, and so on.For example, the Write method of Netty (and the Writeandflush method), after

operation is asynchronous, that is, an IO operation is not blocked to wait for the result of the operation. The program will continue to run down.In Mina, Netty, and twisted, very many network IO operations are asynchronous, and there is one end of write data in the direction network, the connect operation of the client connection server, and so on.For example, the Write method of Netty (and the Writeandfl

Seeing the headline, you might think, what does this have to do with Netty? Indeed, if you are completely using Netty, then you may not need to know selector at all. However, it must be mentioned that the implementation of the Netty underlying NIO is also based on Java selector, which is the encapsulation of selector. Therefore, I personally think that understand

There is already an implementation of the future on the JDK base, which is used to perform asynchronous operations and provides a corresponding method of manipulating the results. However, it also implements its own future within the Netty and inherits the future interface from the JDK, providing additional methods for handling the future in the JDK for asynchronous I/O operations related to Netty The inter

The general process is:First, use the MVN command to create a simple set of Java packages below the specified path.Then, use Jidea to import the MAVEN project to load the created package into the IDE environment. ‘Next, modify the Pom.xml file in the IDE environment, under the associated tag, depending on the needs,Writes the value of the latest version of Netty.The Netty Series function package is then detected in the. java file by invoking the impor

Understanding the basic concept of Netty (http://www.it165.net/pro/html/201207/3173.html), it should be much easier to develop. In the "Hello World" code, we simply printed the simple information on the local side of the binding, and there was no message delivery from the client and the server http://www.it165.net/pro/html/201207/3142.html. This is definitely the most basic function. Before the code, add an important concept in

I. PrefaceAfter reading ROCKETMQ source code, its namesrv and broker communication mechanism use is Netty, so netty generated interest. According to their own general study of the law, are the source code to download, compile, and then the breakpoint has been hit the log debugging.So this article describes how to download the compiled Netty source code under Mac.

As a high-performance asynchronous network development framework, Netty can be used as a framework for the development of various services.A project of the previous time involves the acquisition of real-time data of hardware equipment, using Netty as the implementation framework of the acquisition service, and using RABBITMQ as the communication message queue for the acquisition service and each other modul

As we all know, Netty is a high-performance I/O framework, how to build Web services on it, today, online search an article, learning a bit:Java Servlets has been vastly used in companies for more than all years now. Recently another project from JBoss named Netty have gained on popularity to serve data. From Netty website: "
