谈谈如何使用Netty开发实现高性能的RPC服务器

threadName， Throwable cause) { //收集有非常要封锁通道 ctx.close(); }} /** * @filename:MessageRecvInitializeTask.java * * Newland Co. Ltd.

详细如下： /** * @filename:MessageRecvChannelInitializer.java * * Newland Co. Ltd.

Thread.currentThread().getThreadGroup() : s.getThreadGroup(); } public Thread newThread(Runnable runnable) { String name = prefix + mThreadNum.getAndIncrement(); Thread ret = new Thread(threadGroup， true); b.handler(new MessageSendChannelInitializer()); ChannelFuture channelFuture = b.connect(serverAddress); channelFuture.addListener(new ChannelFutureListener() { public void operationComplete(final ChannelFuture channelFuture) throws Exception { if (channelFuture.isSuccess()) { MessageSendHandler handler = channelFuture.channel().pipeline().get(MessageSendHandler.class); MessageSendInitializeTask.this.loader.setMessageSendHandler(handler); } } }); }} /** * @filename:MessageSendChannelInitializer.java * * Newland Co.

e.getMaximumPoolSize()，运行并发RPC哀求客户端，Java后端高机能处事器开拓，
