Question

我使用的是netty-3.5.11.Final.jar

我的引导程序如下：

val bootstrap = new ServerBootstrap(channelFactory)
bootstrap.getPipeline.addLast("httpDecoder", new HttpRequestDecoder())
bootstrap.getPipeline.addLast("aggregator", new HttpChunkAggregator(1024 * 1024 * 1024))
bootstrap.getPipeline.addLast("httpEncoder", new HttpResponseEncoder())
bootstrap.getPipeline.addLast("deflater", new HttpContentCompressor())
bootstrap.getPipeline.addLast("handler", new HttpRequestServerHandler())
bootstrap.setOption("child.tcpNoDelay", true)
bootstrap.setOption("child.keepAlive", true)

我的handlePost()看起来像是：

def handlePost(context: ChannelHandlerContext, request: HttpRequest) = {
  val response = new DefaultHttpResponse(HttpVersion.HTTP_1_1, HttpResponseStatus.OK)

  val body: Array[Byte] = ....

  response.setContent(ChannelBuffers.wrappedBuffer(body))
  context.getChannel.write(response)
  context.getChannel.close
}

如果我尝试发送长度为260000字节的主体，则它会正确发送。如果我发送一个更大的字节数组，那么我得到以下异常：

为什么我会收到此错误以及如何解决？

Answer 1

netty的重点是异步操作。

写入调用不会阻止等待写入完成。写作和关闭是相互竞争谁将首先完成。您需要注册未来的监听器并在写完成后关闭通道。
