Netty调用service报错

Question

在Netty处理器里面channelRead方法service查询数据库报错

io.netty.channel.DefaultChannelPipeline : 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.

Answer 1

解决方法:

    @Override
    public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
        super.exceptionCaught(ctx, cause);
        Channel channel = ctx.channel();
        //……
        if(channel.isActive())ctx.close();
    }
