netty学习----spring整合netty无法注入bean的问题解决

作者在使用netty集成spring注入调用时普通的@Autowired一直bean注入为null,这里我只是记录针对netty注入spring无法注入bean的解决发放,具体底层实现,希望大神不吝赐教

首先上解决代码块,copy过去就可以直接用

@Component
public class NettyWebSocketServerHandler extends SimpleChannelInboundHandler {


    public static NettyWebSocketServerHandler nettyWebSocketServerHandler;

    //1.正常注入[记得主类也需要使用@Component注解]
    @Autowired
    private IUserInfoService appUserService;
    @Autowired
    private IUserCoinRecordService userCoinRecordService;

    //2.初始化构造方法一定要有
    public NettyWebSocketServerHandler() {

    }

    //3.容器初始化的时候进行执行-这里是重点
    @PostConstruct
    public void init() {
        nettyWebSocketServerHandler = this;
        nettyWebSocketServerHandler.appUserService = this.appUserService;
        nettyWebSocketServerHandler.userCoinRecordService = this.userCoinRecordService;
    }

    /**
     * 管道初始化
     *
     * @param ctx
     * @param msg
     * @throws Exception
     */
    @Override
    protected void channelRead0(ChannelHandlerContext ctx, TextWebSocketFrame msg) throws Exception {
        System.out.println("收到消息: " + msg.text());
        String info = DataParamsComm.analysisData(msg.text());
        System.out.println("解密数据:" + info);
        //4.这里是调用方法需要通过另一个bean去调用,你真正使用的bean
System.out.println(nettyWebSocketServerHandler.appUserService.findByUserId(500001L));
        ctx.channel().writeAndFlush(new TextWebSocketFrame("接收到的内容: " + JSON.toJSONString(nettyWebSocketServerHandler.appUserService.findByUserId(500001L))));

    }
}

这样就解决了spring整合netty无法注入bean的问题,现在bean在netty中正常的业务调用了
