我启动了一个带有多个业务线程的 netty4 nio 服务器,用于处理如下的长期业务
public void start(int listenPort, final ExecutorService ignore)
throws Exception {
...
bossGroup = new NioEventLoopGroup();
ioGroup = new NioEventLoopGroup();
businessGroup = new DefaultEventExecutorGroup(businessThreads);
ServerBootstrap b = new ServerBootstrap();
b.group(bossGroup, ioGroup).channel(NioServerSocketChannel.class)
.childOption(ChannelOption.TCP_NODELAY,
Boolean.parseBoolean(System.getProperty(
"nfs.rpc.tcp.nodelay", "true")))
.childOption(ChannelOption.SO_REUSEADDR,
Boolean.parseBoolean(System.getProperty(
"nfs.rpc.tcp.reuseaddress", "true")))
.childHandler(new ChannelInitializer<SocketChannel>() {
@Override
public void initChannel(SocketChannel ch)
throws Exception {
ch.pipeline().addLast("decoder",
new Netty4ProtocolDecoder());
ch.pipeline().addLast("encoder",
new Netty4ProtocolEncoder());
ch.pipeline().addLast(businessGroup, "handler",
new Netty4ServerHandler());
}
});
b.bind(listenPort).sync();
LOGGER.warn("Server started,listen at: " + listenPort + ", businessThreads is " + businessThreads);
}
我发现当服务器接受一个连接时只有一个线程在工作。如何引导一台服务器,它只能为一个连接启动多个业务线程?
