Netty boss线程 Accept

纠错   26 Oct 2015

我们知道Netty可以这样创建boss、work的EventLoopGroup，如果nThreads有多个呢，如何处理分配accept的呢？

EventLoopGroup bossGroup = new NioEventLoopGroup(1);
EventLoopGroup workerGroup = new NioEventLoopGroup();

借用下参考资料的图片：

private final class PowerOfTwoEventExecutorChooser implements EventExecutorChooser {
    @Override
    public EventExecutor next() {
        return children[childIndex.getAndIncrement() & children.length - 1];
    }
}

private final class GenericEventExecutorChooser implements EventExecutorChooser {
    @Override
    public EventExecutor next() {
        return children[Math.abs(childIndex.getAndIncrement() % children.length)];
    }
}

这里并不是随机获取线程
