netty channelRead 未自动执行

 1 ServerBootstrap bootstrap = new ServerBootstrap();
 2         try {
 3             bootstrap.group(bossGroup, workerGroup).channel(NioServerSocketChannel.class)
 4                     .childHandler(new ChannelInitializer() {
 5                         @Override
 6                         protected void initChannel(Channel ch) throws Exception {
 7                             ch.pipeline().addLast(
 8                                     new HttpServerCodec(),new HttpObjectAggregator(LOCALPORT), // 将多个消息转换为单一的一个FullHttpRequest
 9                                     new HttpRequestDecoder(),
10                                     new ServcerHandler()    // 自己实现的Handler
11                             );
12                         }
13                     }).childOption(ChannelOption.AUTO_READ, false)
14                     .bind(LOCALPORT).sync().channel().closeFuture().sync();

因为设置了

childOption(ChannelOption.AUTO_READ, false)

所以在执行完

public void channelActive(ChannelHandlerContext ctx)

方法后,不会自动执行

public void channelRead(ChannelHandlerContext ctx, Object msg) 方法;

需要在channelActive中添加这行语句才会调用channelRead方法:

ctx.channel().read();
