java - netty的紧密连接

Question

我有一个使用 的项目，Netty但存在一些问题：

如果connection闲置一段时间，是否connection会自行关闭？如果它自己关闭，我该如何设置关闭时间？

有5个线程，他们发送100个数据。他们使用相同的频道，例如

 /** release connect*/
    public void closeConnect(ChannelFuture writeFuture){
    if(writeFuture != null){
        writeFuture.awaitUninterruptibly();
    }
    future.getChannel().close();
    future.getChannel().getCloseFuture().awaitUninterruptibly();
    client.releaseExternalResources();
    }

    //write data
    ChannelFuture future = Channels.write(data);
    closeConnect(future);

上面的代码将产生一个closeChannelexception. 我的问题是：如何避免异常？

此外，当我ReadTimeoutHandler在客户端使用并设置timeout= 5s，并使线程休眠 6s 时，就会ReadTimeoutException发生。当我调用e.getChannel().close()时，它还会创建一个closeChannelException. 如何自己处理异常或无异常关闭连接？

Answer 1

You could catch ReadTimeoutException if the API throws it and then call your closeConnect(...).

Seems to me though, that the channel is already closed; so either just ignore CloseChannelException or handle it if it affects the program state.

Answer 2

试试这个方法：

/** 释放连接*/

public void closeConnect(ChannelFuture writeFuture){
if(writeFuture != null){
    writeFuture.awaitUninterruptibly();
}
future.getChannel().getCloseFuture().awaitUninterruptibly();
future.getChannel().close().awaitUninterruptibly();
client.releaseExternalResources();
}

//write data
ChannelFuture future = Channels.write(data);
closeConnect(future);

尝试先关闭 channelFuture，然后再关闭自己的频道。
