NettyServerHandler中注入其他类为空解决办法:

增加如下代码

  public static NettyServerHandler nettyServerHandler;
    @PostConstruct
    public void init() {
        nettyServerHandler = this;
    }

整个类代码如下：

@Component
public class NettyServerHandler extends ChannelInboundHandlerAdapter {

    @Autowired
    private RedisTemplate redisTemplate;
    @Autowired
    private GetTime getTime;

    public static NettyServerHandler nettyServerHandler;
    @PostConstruct
    public void init() {
        nettyServerHandler = this;
    }

    @Override
    public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception  {
        ByteBuf in = (ByteBuf)msg;
        int readableBytes = in.readableBytes();
        byte[] bytes =new byte[readableBytes];
        in.readBytes(bytes);

        if (bytes != null && bytes.length >= 3748) {
            if (    bytes[0]==-86&&
                    bytes[1] == -85 &&
                            bytes[2] == -84 &&
                            bytes[3745] == -70 &&
                            bytes[3746] == -69 &&
                            bytes[3747] == -68
            ) {
                String encode = Base64.getEncoder().encodeToString(bytes);
//                nettyServerHandler.redisTemplate.opsForValue().set("Current:Data",encode);
                nettyServerHandler.redisTemplate.opsForList().rightPush("Current:Data"+nettyServerHandler.getTime.DateDisplay() , encode);
            }
        }
    }

    @Override
    public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) {
        // 打印异常信息
        cause.printStackTrace();
        ctx.close();
    }
}
