Netty中的channelInactive和channe.closeFuture（）。addListener（）有什么区别

Question

 public class ChannelActiveHandler extends SimpleChannelInboundHandler {


    @Override
    public void channelActive(ChannelHandlerContext ctx) throws Exception {
        System.out.println("channel open");

        // add closeListener
        ctx.channel().closeFuture().addListener(future->{

            // do somthing when channel is close!
            System.out.println("channel close! state："+ctx.channel().isActive());
        });

        super.channelActive(ctx);
    }


    @Override
    public void channelInactive(ChannelHandlerContext ctx) throws Exception {

        // do somthing when channel is close!
        System.out.println("channel inactive！");
        super.channelInactive(ctx);
    }

}

如上所述，Netty中的channelInactive()和channel.closeFuture().addListener()有什么不同。当通道关闭时，将调用两种方法。

两种方法都能达到相同的效果吗？
