背景
在看Qos模块的时候发现,pipeline中添加了IdleStateHandler来检测心跳,但是后面的Handler中,并没有发现处理心跳事件的地方,这个是不是漏掉了心跳的处理,超过5分钟断开连接呢?
@Override
protected void decode(ChannelHandlerContext ctx, ByteBuf in, List<Object> out) throws Exception {
if (in.readableBytes() < 1) {
return;
}
// read one byte to guess protocol
final int magic = in.getByte(in.readerIndex());
ChannelPipeline p = ctx.pipeline();
p.addLast(new LocalHostPermitHandler(acceptForeignIp));
if (isHttp(magic)) {
// no welcome output for http protocol
if (welcomeFuture != null && welcomeFuture.isCancellable()) {
welcomeFuture.cancel(false);
}
p.addLast(new HttpServerCodec());
p.addLast(new HttpObjectAggregator(1048576));
p.addLast(new HttpProcessHandler());
p.remove(this);
} else {
p.addLast(new LineBasedFrameDecoder(2048));
p.addLast(new StringDecoder(CharsetUtil.UTF_8));
p.addLast(new StringEncoder(CharsetUtil.UTF_8));
p.addLast(new IdleStateHandler(0, 0, 5 * 60)); //心跳检测
p.addLast(new TelnetProcessHandler());
p.remove(this);
}
}```
