netty s application

One, the basic methodThe previous section implements the basic connection of the Netty, which joins spring to manage the Netty and the spring to open the Netty service.In the Netty server, we set up three classes: HelloServer (program main entry), Helloserverinitializer (transfer channel initialization), Helloserverhan

IOS AsyncSocket and Java Netty simple socket usageIn the past two days, I have taken a brief look at the Netty framework. Netty provides asynchronous, event-driven network application frameworks and tools to quickly develop high-performance, high-reliability network servers and client programs. That is to say,

Onecoder this weekend, and the new home does not have a network, the task of this week's translation has not been completed, the next Monday onwards, first on a comparison of Oio and NiO small research.Netty not only supports the NIO model in Java, but also provides support for the OIO model. (New io vs old io).First, in Netty, switching between the OIO and NiO two modes is very convenient, only need to initialize different channel works. serverboots

Netty provides asynchronous, event-driven network application frameworks and tools for rapid development of high-performance, high-reliability network servers and client programs [official definition], Overall, it contains the following: 1. Provides rich protocol codec support, 2. Implement your own buffer system, reduce the cost of replication, 3. The complete channel implementation, 4. Event-based process

The so-called framework is basically a function: to provide a more convenient progra

and can be quickly released when not in use. It also provides a way to access the array directly by Bytebuf.array () to get the byte[data. Accessing an array of non-heap buffer bytebuf causes unsupportedoperationexception, and you can use Bytebuf.hasarray () to check whether the array is supported.Direct buffer (immediate buffers) A direct buffer that allocates memory directly beyond the heap. The direct buffer does not consume heap space capacity, and should be used with the maximum memory cap

array, you might be more inclined to use heap memory. Compound byte buffer (composite buffers) The third and final pattern, using composite buffer, is a unified view of multiple BYTEBUF instances (an aggregated view of multiple Bytebufs). With this pattern, you can add or remove bytebuf instances on demand, a feature that JDK Bytebuffer does not have at all. The Netty uses the Bytebuf subclass Compositebytebuf to implement this pattern, putting multi

In the work with Netty do a few services, feel Netty do good program performance, less resources, but the implementation of HTTP service is more troublesome, so reference spring MVC annotations based on Netty implementation of a lightweight restful framework.The framework provides functions such as controller annotations, global exception controllers, interceptor

NiO in Java is a basic technique for solving blocking IO problems, but the preparation of NIO is a high requirement for Java programmers. Then Netty is a sophisticated network IO programming framework for simplifying operations. Here is a brief introduction of a program, the code is "Netty in action" inside, but the inside of the example is a bit of a problem, anyway I did not run successfully, modified aft

I. INTRODUCTION of Netty FrameworkWhat is Netty? First look at the explanation of Baidu Encyclopedia:Netty is a Java open source framework provided by JBoss. Netty provides asynchronous, event-driven network application frameworks and tools for rapid development of high-performance, high-reliability network servers and

1. PrefaceThe previous chapter, in conjunction with the Java NiO example, explains a basic use of multi-channel IO multiplexing, which is deepened by actual coding. This chapter began to enter the Netty link, the previous two chapters are for Netty to pave the instructions. This section will compare Java's nio example to illustrate a basic design of Netty, which

, otherwise it is difficult to form a coherent thinking.In the first article we first look at what Netty is and the members of the Netty, which can be said to be an appetizer and the basis for learning later.To apply Netty's official website:Netty is an asynchronous, event-driven network application framework that can rapidly develop high-performance network Prot

API, low development threshold; Powerful, preset a variety of codec functions, support a variety of mainstream protocols; The ability of customization is strong, and the communication framework can be flexibly expanded by Channelhandler; High performance, compared with other industry mainstream NIO framework, the Netty is optimal. Mature, stable, netty fixes all the JDK NiO bugs that have b
