Netty ChannelRead方法没有被调用 [英] Netty ChannelRead method is not getting invoked

问题描述

在我的netty示例中，如果我将ServerBootstrap的AUTO_READ选项配置为false.然后在我相应的处理程序中，从不调用ChannelRead方法，仅在调用ChannelActive.但是，如果我删除了AUTO_READ选项，则一切正常，两个方法都被调用.

Hi In my netty sample if I configure my ServerBootstrap with AUTO_READ option as false. Then in my corresponding handler ChannelRead method is never getting invoked, only ChannelActive is getting invoked. However if I remove the AUTO_READ option then everything is working and both the methods are getting invoked.

我在这里错过了一些非常基本的东西吗?

Am I missing something very basic here?

推荐答案

当AUTO_READ设置为false时，除非您显式调用channel.read();

When AUTO_READ is set to false, no read operation occurs until you explicitely call channel.read();

将其设置为true时，将自动允许读取并传递给处理程序.

When you set it to true, then read are automatically allowed and passed up to the handlers.
