1. Preface netty encapsulates FastThreadLocal to replace the ThreadLocal provided by jdk. Combined with the encapsulated FastThreadLocalThread, variables in multithreaded environment improve the query and update efficiency of ThreadLocal objects. In the following, by comparing ThreadLocal with FastThreadLocal, and by analyzing the source code, ...

Netty is a network application framework based on Java NIO. Netty is a NIO client-server (client server) framework, using Netty can quickly develop network applications, such as server and client protocols. Netty provides a new way to develop network applications, which makes it easy to use and extensib ...

Preface Now there are many examples of using Netty to build RPC framework on the Internet. Why do I write an article here to discuss it? I know very well that I may not have written them so well. There are two reasons why we should write about it: First, because after learning Netty, we need to practice constantly to better grasp the use of Ne ...

Because the ByteBuffer provided in JDK can not be dynamically expanded and the API is complex to use, Netty provides ByteBuffer. The API of Bytebuf is more convenient and can be expanded dynamically. It provides a variety of implementations of Bytebuf and an efficient zero-copy mechanism. Operation of ByteBuf ByteBuf has three important attribu ...

The server is very simple. It only needs an annotation @EnableTransaction Manager Server configuration on the startup class to turn on the distributed transaction server function. First, start the entrance. Annotation @Enable Transaction Manager Server @Retention(RetentionPolicy.RUNTIME) @Target(E ...

Case introduction When we implement the rpc framework, we need to choose the communication mode of socket. And we know that in general, socket communication is similar to qq chat, sending messages in the past, and when to reply. But our rpc framework communication, which feels like an http call, needs t ...
