处理一个netty异常

AM io.netty.channel.DefaultChannelPipeline$TailContext exceptionCaught

WARNING: An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.

处理方式：
     处理业务的handler里面增加

public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {  
        ctx.close();  
    }
