发送端把对象转为JSON字符串,

 public <T>boolean sendToQueue(String queueName, T data){
        try{
            amqpTemplate.convertAndSend(queueName, JSON.toJSONString(data));
            return true;
        }catch (Exception e){
            return false;
        }
    }

接收端解析的时候报错:com.alibaba.fastjson.JSONException: syntax error, expect {, actual error, pos 0

JSONObject.parseObject(s, QrSignInData.class);

解决办法如下:

 @RabbitListener(queues = "MAIN_QUEUE")
    public void process(String data){
        System.out.println(data);
        log.info("[RabbitMQ]----收到消息:{}",data);
        final JSONObject jsonObject = JSONObject.parseObject(data);
        final String qq = jsonObject.getString("qq");
        final String s = jsonObject.toJSONString();
        log.info(qq);
        try{
           final QrSignInData qrSignInData = JSONObject.parseObject(s, QrSignInData.class);
           iMacUserService.toUpdateUserPoint(qrSignInData);
       }catch (Exception e){

       }
    }
