hi,all:
I use DelimiterBasedFrameDecoder and ByteToMessageDecoder to decode my
message in TCP keepalive.
the server code:
bossGroup = new NioEventLoopGroup(1)
workerGroup = new NioEventLoopGroup
val bootstrap = new ServerBootstrap()
bootstrap.group(bossGroup, workerGroup)
.channel(classOf[NioServerSocketChannel])
.option[Integer](ChannelOption.SO_BACKLOG, 10000)
.option[java.lang.Boolean](ChannelOption.TCP_NODELAY, true)
.option[java.lang.Boolean](ChannelOption.SO_KEEPALIVE, true)
.childHandler(new ChannelInitializer[SocketChannel]() {
override def initChannel(ch: SocketChannel): Unit = {
val p = ch.pipeline
p.addLast(sslCtx.newHandler(ch.alloc))
val delimiter = Unpooled.copiedBuffer(Const.delimiter)
p.addLast(new DelimiterBasedFrameDecoder(204800, delimiter))
p.addLast(new ServerMsgDecoder)
p.addLast(new ServerMsgEncoder)
p.addLast(new ServerHandler)
}
})
ServerMsgDecoder extends from ByteToMessageDecoder.
But when I run my application, sometimes it will has some problem,the
ServerMsgDecoder loop process the same one message
forever, and then my server is abnormal.

..........
..........
..........more and more same message
the '4^X�^@^@^@^M1463931910119' is in.toString which is the param of decode
method in ServerMsgDecoder extends ByteToMessageDecoder
override def decode(
ctx: ChannelHandlerContext,
in: ByteBuf, out: util.List[AnyRef]
)
can someone help me? what happend? it caused by tcp packet splicing？
