NioEventLoopGroup的无参构造： 1 public NioEventLoopGroup() { 2 this (0 ); 3 } 调用了单参的构造： 1 public NioEventLoopGroup( int nThreads) { 2 this (nThreads, (Executor) null ); 3 } 继续看到双参构造： 1 public NioEventLoopGroup( int nThreads, Executor executor) { 2 this (nThreads, executor, SelectorProvider.provider()); 3 } 在这里是使用JDK中NIO的原生API：SelectorProvider的provider，产生了一个SelectorProvider对象调用，继续调用三参构造。 关于SelectorProvider在我前面的博客中有介绍过： 【Java】NIO中Selector的创建源码分析 ，在Windows下默认创建了WindowsSelectorProvider对象。 继续看三参构造： 1 public NioEventLoopGroup( int nThreads, ThreadFactory threadFactory, SelectorProvider selectorProvider) {

目录 Part 1. What's Selector? Part 2. Why Selector? Part 3. How to use Selector? 1) Create Selector 2) Channel's Register 3) Selection Key 4) Selector.select() 5) Selector.selectedKeys() Part 4. Demo Train Part 1. What's Selector? Selector is the core conception for NIO from JDK1.4 which is a multiplexor of SelectableChannel objects that allows one thread to handle multiple channels. Part 2. Why Selector? Before NIO came out, We used Socket programming like this： //---Server--- //Create ServerSocket and bind the port ServerSocket serverSocket = ……; serverSocket.bind(8899); While (true) { //

创建NioEventLoopGroup NioEventLoopGroup提供了很多构造方法，下面以参数最完整的构造方法为例： public NioEventLoopGroup ( int nThreads, ThreadFactory threadFactory, final SelectorProvider selectorProvider, final SelectStrategyFactory selectStrategyFactory) { super (nThreads, threadFactory, selectorProvider, selectStrategyFactory, RejectedExecutionHandlers.reject()); } public NioEventLoopGroup ( int nThreads, Executor executor, EventExecutorChooserFactory chooserFactory, final SelectorProvider selectorProvider, final SelectStrategyFactory selectStrategyFactory, final RejectedExecutionHandler rejectedExecutionHandler) { super
